Chapter 200 Ripples
March 13th.
Munich, Bosch Sensors Division Headquarters, 9:15 AM local time.
Klaus Stein arrived at his office at exactly eight o'clock, a full hour earlier than he usually did. His secretary hadn't arrived yet, the coffee machine was still cold, and the corridor was empty except for the white light of the emergency lights.
During that hour, he did one thing—he watched the recording of last night's IEEE MEMS session again from beginning to end.
At nine o'clock sharp, he dialed Albrecht's office phone.
Are you free this morning? I need to give a report in person.
Albrecht is the president of Bosch's sensor division. He manages Bosch's global sensor business, which generates over two billion euros in annual revenue and employs more than 6,000 engineers. Within Bosch's power structure, Albrecht is someone who can speak directly to the board of directors.
"What is it?" Albrecht's voice carried the languor of the morning.
"Wei Lan."
There was a two-second silence on the other end of the phone.
"9:30, my office."
……
When Stein walked into Albrecht's office, he was holding a report that was only four pages long. He had finished writing it at three in the morning, printed it out, and then manually revised it in three places.
"Speak," Albrecht gestured for him to sit down.
Stein did not sit down. He placed four pages on Albrecht's desk, then stood there and, in less than five minutes, gave a complete retelling of what had happened the previous night.
His manner of narration was the same as when he asked questions at academic conferences—precise, calm, and unemotional. But Albrecht had known Stein for almost fifteen years, and he could hear the barely suppressed urgency in the technical director's voice.
When Stein spoke of Akira Ishikawa's independent data, Albrecht finally sat up straight in his chair.
"You mean, a professor from the Tokyo Institute of Technology independently verified Vilan's theoretical model using a completely different process and a completely different materials system?"
"Yes. Sixteen sets of data, with an average deviation of 0.83 percent."
Albrecht picked up the four pages on the table and turned to the third page. Stein had drawn a red box around a passage on that page:
Conclusion: Vilan's three-tier model has received triple independent validation (in-house experimental line, commercial customer integration testing, and third-party independent laboratory). The model's universality and predictive accuracy both exceed my previous assessment. I recommend adjusting Vilan's threat level from "Observation" to "Urgent Assessment".
Albrecht put down the paper.
What was your previous assessment?
"Three months ago, my assessment was that while Vilan's theory had some innovative aspects, commercialization would take at least eighteen to twenty-four months," Stein said. "I was wrong. Their commercialization data came at least eighteen months ahead of my expectations."
Albrecht tapped his fingers lightly twice on the table. It was a habitual gesture he made when he was thinking.
"Where's our 400mm roadmap? The white paper says mass production will begin in the fourth quarter of 2024."
"At the current pace, achieving initial mass production by Q4 2024 shouldn't be a problem," Stein replied. "But the issue isn't whether we can do it; the issue is—by the time we do, how many sensors will Vilan have already sold on the market?"
He paused for a moment.
"Mr. Albrecht, frankly speaking, we invested 180 million euros to upgrade our 400mm production line. That's forty times the total investment Vilan has ever made. But with one-fortieth of that investment, they've already surpassed us in theoretical precision."
The office remained quiet for a long time.
Finally, Albrecht spoke up: "What is your suggestion?"
"Two parallel approaches," Stein said. "First, accelerate our own 400mm R&D, especially in thermoelastic coupling modeling. I suggest forming a dedicated team to study the applicability of the third-order model. Second—initiate a technical cooperation assessment ahead of time. If Vilan's model is indeed as universally applicable as Ishikawa Akira's data shows, then instead of spending two years deriving it from scratch, we should directly discuss cooperation and licensing."
Albrecht looked into Stein's eyes.
"Are you serious? Bosch—talking about technology licensing with a Chinese startup?"
"I'm serious." Stein didn't avoid his gaze. "Mr. Albrecht, our 180 million euro investment won't be wasted. But if we ignore the theoretical advantages of Villen, then that 180 million euro will truly be at risk."
Albrecht was silent for a moment again. Then he picked up the phone and dialed an internal number.
"Schedule an executive meeting next Tuesday, adding one item to the agenda—a technology assessment and feasibility analysis for cooperation with Vilan. Notify the strategy department, legal department, and Asia-Pacific regional head to attend."
After hanging up the phone, Albrecht looked at Stein.
"Your report—add some more details, make it a complete assessment document. Give it to me by next Tuesday."
"clear."
Stein turned and walked out of the office. Sunlight streamed through the floor-to-ceiling windows in the corridor, casting neat rows of shadows on the marble floor. As he walked past those shadows, only one number kept replaying in his mind.
00:021.
±0.021°/h.
A number that he, a sensor engineer for twenty years, couldn't reliably achieve on a mass production line was accomplished by a group of young people using a standard production line.
……
the same day.
Milan, STMicroelectronics MEMS Business Unit.
Marco Bertoli opened his laptop in his office. On the screen was the monthly report he hadn't finished writing the night before.
He stared at the "Plan B" section of the report for a long time.
A month ago, he wrote in his report: "Plan B (Tracking Research on a Novel Modeling Method for MEMS Thermoelastic Coupling) – Progress Assessment: In the initial stage, there is a lack of sufficient data to support a feasibility assessment. It is recommended to maintain the current level of resource investment and continue to observe."
The supervisor wrote two words next to that line: "Noted."
Now Bertoli moves the cursor over that passage, selects all, and deletes it.
Then he started typing again.
"Option B – Progress Assessment: Major Update. The Vilan third-order model achieved triple independent validation in the IEEE MEMS 2021 session (using proprietary experimental data, commercial customer integration test data, and independent validation data from Akira Ishikawa's laboratory at the Tokyo Institute of Technology). The model's universality and accuracy far exceed previous assessments. Particularly noteworthy is the model's high-precision predictive capability across different process routes and material systems."
He paused for a moment, then continued writing.
"Recommendation: Prioritize Option B from 'monitoring' to 'proactive evaluation.' We recommend initiating internal replication calculations in Q2 to assess the applicability of the third-order model to STMicroelectronics' existing 300mm production lines. We also recommend that the strategy department assess the feasibility of establishing a technical exchange channel with Vilan."
After writing it, he read it over. He deleted the sentence, "It is recommended that the strategy department assess the feasibility of establishing a technical exchange channel with Vilan."
too early.
He knew his supervisor wouldn't approve such a "skip-step" suggestion. STMicroelectronics' decision-making process, like its product line, is slow, incremental, and doesn't allow skipping levels. First, they do internal replication to obtain their own data, and then they discuss the next step.
But he knew in his heart that this "next step" would come sooner than anyone expected.
……
the same day.
Stuttgart, Infineon headquarters.
Franz Weber sat at his desk, three printed documents laid out before him. The first was an arXiv preprint of the Villand third-order model, sixty-eight pages long, its edges worn from repeated use. The second was the conference minutes of the IEEE MEMS session, typed by hand himself. The third was a blank sheet of paper with only a few lines of text.
The white paper reads:
Assessment Conclusion (Pending):
Vilan's third-order model -
Impact on Infineon —
Suggested Actions—
There are blank spaces after the three horizontal lines.
Weber had been conducting "research" for the past three months. This was the term he used when reporting to his superiors—"research" meant there were no conclusions yet, that information was still being gathered, and that no decisions needed to be made.
But after last night's IEEE MEMS session, the word "research" was no longer sufficient.
He picked up his pen and wrote four words after the first horizontal line.
"This needs to be taken seriously."
Weber was the typical German engineer—conservative, meticulous, and not quick to draw conclusions. Within Infineon, he was jokingly referred to by his colleagues as "the last person to be convinced." If Weber said "this needs to be taken seriously," it was essentially equivalent to others saying "this is a major threat."
He wrote after the second line: "If the third-order model is widely adopted by the industry, Infineon's existing thermoelastic coupling modeling methods will risk becoming completely outdated."
After the third line, write: "It is recommended to initiate an internal special assessment."
After he finished writing, he folded the white paper and put it in his shirt pocket.
Used at tomorrow's departmental meeting.
……
March 15th.
Shanghai, Vilan Microelectronics Technology Co., Ltd.
In Lin Wei's office, Mr. Wang, the general manager of Jingce Microelectronics, sat opposite her, looking somewhat uneasy.
"Mr. Lin, I'm here today to discuss future cooperation," said Mr. Wang.
Lin Wei looked at him.
Last week, President Wang was still hesitant about whether to "bet on two fronts"—maintaining his membership in the Weilan Alliance while secretly contacting Bosch Asia Pacific. Lin Wei knew about this because news within the alliance could never be kept secret.
"Please speak, Mr. Wang," Lin Wei said calmly.
"I watched the replay of the IEEE MEMS conference," Mr. Wang said, rubbing his hands together. "Professor Ishikawa Akira's data—that independent verification—has really made me rethink a lot of things."
He paused, as if organizing his thoughts.
"I did have some hesitation before. But now I want to make it clear—Jingce Microelectronics will not engage in 'double-crossing'. We fully support the Weilan Alliance."
Lin Wei did not respond immediately.
She picked up the teacup on the table and slowly took a sip. When she put the cup down, her expression remained calm.
"Mr. Wang, I have received your statement."
That's all. There were no follow-up questions, no doubts, and no polite phrases like "let bygones be bygones."
Mr. Wang paused for a moment, then nodded. He understood what Lin Wei hadn't said aloud—he knew her wavering, and he accepted her return. But once trust is broken, it takes time and action to mend it; a simple statement isn't enough.
After Mr. Wang left, Lin Wei took out her phone and glanced at it. Chen Jun from Zhenxin had sent her a message: "The additional order contract has been stamped, and the electronic version will be sent to you this afternoon. There's another matter I'd like to discuss—can you deliver the next batch as early as mid-April? Our downstream autonomous driving prototype verification is on a tight schedule."
Lin Wei replied, "I'll coordinate the production line schedule and get back to you tomorrow."
After putting down her phone, she sat at her desk for a few seconds.
One hundred thousand units. Adding other customers' regular orders, Vilan's Q2 production capacity is nearing saturation. Even with Hongyuan's two machines operating at full capacity, they can barely meet demand. Fortunately, their self-built packaging line is expected to go into production in May, at which time the bottleneck will be somewhat alleviated.
But this also means another thing—when production capacity is insufficient, choices must be made. Who should be prioritized for supply, and which customers' orders should be postponed? This is a problem that a CEO least wants to face, but must confront.
She turned on her computer and began adjusting the Q2 production capacity allocation table.
……
the same day.
Cyberspace.
On Zhihu, the question "How to evaluate the performance of the Villan third-order model at IEEE MEMS 2021" received more than 200 answers within three days.
The top post wasn't a lengthy analysis by an industry expert, but rather an update from an anonymous user with the screen name "Calm Analyst".
Three months ago, this person posted a 3,000-word analysis, concluding that "remain cautiously optimistic and wait for the paper." That post received 3,200 likes and was the most popular answer in discussions related to Vilan at the time.
His new post is only 400 characters long:
In my previous post, I said "remain cautiously optimistic." Now I'm revising my view. The IEEE MEMS special session showed me three things: First, all fifteen sets of experimental data accurately predicted the S-shaped transition, which wasn't just luck. Second, the commercial integration data from Zhenxin shows that this model can not only explain the phenomenon but also guide production. Third, Akira Ishikawa's independent data essentially puts an end to the skepticism of "self-justification."
I take back the word 'cautious'. Now only 'optimistic' remains.
But the peer review results remain crucial. Without NM's formal publication, this is merely 'insider consensus,' not 'industry standard.' So—keep waiting. But this time, the mindset is different.
Six hours after the post was published, it received 4,100 likes. The most upvoted comment was only two words:
"Feel the same."
……
On another platform, a quieter change is taking place.
Professor He Wentao of the School of Microelectronics at Fudan University—the same scholar who wrote the "calm analysis" article that garnered 120,000 views—has not updated any content about Wei Lan on his personal Weibo account for three consecutive days.
His previous Weibo post was a repost of the IEEE MEMS 2021 agenda link, with only one sentence in the caption: "Tonight's panel discussions are worth paying attention to."
After that, I never posted any more comments.
Professor Liu Jianping of Tsinghua University also chose to remain silent. He posted a photo of cherry blossoms in full bloom on campus on his WeChat Moments with the caption "Spring is here," without mentioning MEMS or Vilan at all.
Their silence was more persuasive than any words.
In academia, when a scholar who previously openly questioned a theory suddenly falls silent, it only means one thing—
They couldn't find any angle to question it.
……
March 18th.
Beijing, East China University of Science and Technology, Micro-Nano Manufacturing Research Center.
Su Chen sat at a small table in the corner of the lab, two windows open on his laptop screen. The left one was the status page of the NM submission system—ID NM-2020-12-25-00847, status: Under Review. This status had been displayed for almost two months.
On the right is a blank Word document, with the cursor blinking on the first line.
The document's title is already set: "Multi-platform Validation of Third-order Nonlinear MEMS Thermal-Elastic Coupling Model: From Laboratory to Commercial Production".
The framework of the second paper.
Su Chen's fingers hovered above the keyboard, but he didn't press any keys. He was thinking about Ishikawa Akira's data.
Sixteen independent tests were conducted, with an average deviation of 0.83%. The SOI substrate and deep reactive ion etching process are completely different from Vilan's process route. If we add Ishikawa Akira's data, Zhenxin's commercial data, and Vilan's own experimental data—three completely independent platforms, three completely different process routes, and a complete chain from laboratory to commercial mass production—this is no longer a "verification paper".
This is a foundational paper that establishes the third-order model as the industry standard modeling method.
But this is contingent on the first paper passing the review.
Su Chen glanced at the window on the left. Under Review.
Unbeknownst to him, somewhere on the other side of the world, one of NM's three anonymous reviewers—a senior scholar who had worked in the field of MEMS thermodynamics for over twenty years—was sitting in his study with two windows open in front of him as well.
On the left is Su Chen's team's paper manuscript, 68 pages long, with 147 formulas and 48 charts. He has already read it three times.
On the right is a video replay of the IEEE MEMS 2021 special session discussion.
Two months ago, he wrote in his initial review comments: "The theoretical derivation of the model is rigorous, but it lacks sufficient independent validation data to support its generalizability claim. It is recommended that the authors supplement the data with more validation experiments on independent platforms."
He stared at the sixteen sets of data that Ishikawa Akira was showing in the video, and remained silent for a long time.
Then he opened NM's peer review system and slowly typed a line in the "Additional Comments" section:
"I have recently become aware of additional independent validation data that significantly strengthens the authors' claims. I would like to revise my initial assessment."
After finishing typing, he did not submit it immediately.
He reviewed Ishikawa Akira's data again.
Then I pressed the submit button.
……
Late at night on March 20th.
Su Chen's phone vibrated beside his pillow.
He groggily reached over and glanced at it—it was an automatic notification email from the NM submission system.
Title: "Manuscript NM-2020-12-25-00847 — Status Update"
He suddenly became fully awake.
I opened the email. It contained only a few short lines:
Dear Dr. Su,
The review of your manuscript entitled "Third-order Nonlinear Extension: Theoretical Framework, Experimental Validation, and Scale Extrapolation for MEMS Thermal-Elastic Coupling" has been completed. The editor has made a decision regarding your manuscript.
Please log in to the submission system to view the decision and reviewer comments.
Su Chen's fingers trembled slightly.
It wasn't fear, but rather the instinctive reaction of finally receiving a response after a long wait.
He opened the submission system.
The two words displayed in the decision bar made him stare at them for a full ten seconds.
Major Revision.
Significant revisions are needed.
It wasn't a rejection.
Su Chen placed his phone screen face down on the pillow and closed his eyes.
In the darkness, he let out a long breath.
Major Revision—in academia, this means there's hope for acceptance, but extensive revisions and additions are required. For a 68-page paper proposing a completely new theoretical framework, this is a rather positive sign.
He Wentao wrote in his article that NM's rejection rate exceeds 90%.
They were not rejected.
Su Chen opened his eyes in the darkness. Then he picked up his phone and sent a message to Zhou Zhiyuan.
"Professor Zhou, the peer review results for NM are in. Major Revision."
After sending it, he added another sentence:
"The revised material framework has already been prepared. It consists of three parts: supplementary experimental methods, expansion of the S-shaped transition theory, and enhanced statistical analysis. Now we can enter the final data."
1:23 AM.
Zhou Zhiyuan's reply has arrived:
"Okay. We'll have a meeting tomorrow morning to discuss the revision strategy. We'll also take Ishikawa Akira's data into account—we already have it if the reviewers request additional independent verification."
Su Chen put down his phone and lay back down on his pillow.
A small patch of moonlight shone through the gap in the curtains that weren't fully drawn.
He gazed at the moonlight, his mind already racing—how long would the revision take? If the reviewers' comments focused on independent validation and statistical analysis, the existing revision framework could largely cover that. Ishikawa Akira's data was a key addition. The additional order of 100,000 units from Zhenxin also corroborated this. At the fastest possible pace—three to four weeks—the revision could be completed and submitted.
Then comes the second round of peer review. This usually takes one to two months.
If all goes well, the paper could be officially published as early as June.
June.
When Su Chen closed his eyes, what appeared in his mind was not the layout of the NM journal, but a much larger picture—the publication of the paper meant that the third-order model had gained formal recognition from the academic community, Ishikawa Akira's second paper could be submitted immediately, Bosch and STMicroelectronics had to face this new theory in a formal way, and Vilan's technical barrier was upgraded from "trade secret" to "academic consensus".
And all of this started with the first third-order correction term he calculated in that small laboratory, using a pen and a stack of draft paper.
A breeze was blowing outside the window. Beijing in March still carried the lingering chill of winter, but Su Chen knew that spring had indeed arrived.
It's not just the kind of spring with cherry blossoms.
