Chapter 210 Same Table
9:30 a.m.
Su Chen finished the first part of his report.
He used a sentence as a transition: "This theoretical framework shows that, regardless of the platform's specific parameters, as long as it is uniformly implemented in a thermally non-uniform microelectromechanical system architecture, the error will be controlled within five percent."
It's not "we hope". It's not "maybe". It's "it can be deduced".
He is putting forward a verifiable assertion.
"Next, we move on to the second part – multi-platform verification."
The slideshow transitions, listing the names of five validation institutions in sequence: ETH Zurich, Purdue University, National Chiao Tung University, and MIT, along with preliminary data including Kosuke Yamamoto's preprint and data calibrated using the Materials Expansion Protocol.
Each verification institution provided a comparison chart of predicted and experimental results. The deviation ranged from 1.2 to 4.1. The only deviation exceeding 10 was for the uncalibrated version of the piezoelectric ceramic data from Yamamoto, with a value of 12.7. However, he also provided the corresponding data after calibration: 3.2.
3.2%. This is 9.5 percentage points different from the uncalibrated version. Only one variable was changed: parameter calibration.
Across the table, Graf turned another page of his notes.
Stein glanced at the paper document he had brought in advance. It was a three-page report on Bosch's internal reproduction experiment, which His Excellency had only glanced at in three minutes in the shareholders' meeting a few months ago.
The core content of the report is that Bosch completed reproduction tests on three product lines, with a deviation range of 1.8 to 3.5.
Comparing the five sets of independent verification data just presented by Vilan, Bosch's internal data all fall within the same range.
This fact itself is a statement: Bosch can independently reproduce the data, and the reproduction results are consistent with the publicly available data, which means that the third-order model has reached the standard of "independent reproducibility".
In the industrial sector, the ability to reproduce independently signifies only one thing: the technology no longer belongs to a single company and can be integrated into the entire industrial system, becoming a general-purpose public technology.
"The next part is the third section – industrial application."
Su Chen switched the slides.
Three sets of core terms appear on the new page:
Material Extension Protocol.
Digital twin integration.
Production line simulation.
Graf's fingertips twitched slightly as his gaze fell on the third noun.
Su Chen began his explanation with the first item, discussing his joint research with Kosuke Yamamoto, but did not disclose the specific implementation mechanism. He mentioned that "material characteristic coefficients possess generalized derivable properties," which remains an open research topic, while also pointing out that theoretically, classification and derivation can be completed based on crystal structures.
He only spent eight minutes explaining this part.
The second part, a six-minute presentation on digital twins, explained that this was a follow-up research direction of the second paper, aiming to demonstrate that the third-order model can serve as the underlying foundational model for digital twins, enabling real-time prediction of production line conditions.
However, he focused his explanation on the third item: production line design simulation.
"This is a mid-term result of our internally codenamed project," he said.
He cut out an architecture diagram: the input end inputs production line parameters, the middle is equipped with a computing engine built based on a third-order model, and the output end generates the simulation yield fluctuation range.
"We named this system 'Production Line Simulation.' The principle is very clear: input a set of configuration parameters for a hypothetical microelectromechanical production line, including deposition temperature profiles, etching pressure, and lithography tolerances, and the system uses a third-order model to calculate the expected yield distribution range of the production line."
Graf took out a pen from his coat pocket and wrote a line of text heavily in his notebook.
Stein glanced at Graf.
Graf was a man of few words, rarely speaking up in internal meetings, but every word he uttered hit the nail on the head. His taking notes indicated that the information was of critical value and would be retained.
Su Chen continued to elaborate:
"The core value of this system lies in the new production line planning stage. A brand-new microelectromechanical production line typically takes three to eight months from solution design to qualification certification, with an investment cost of ten to forty million US dollars. With the help of simulation tools, the solution iteration cycle can be reduced by about 30%, and the financial losses caused by repeated trial production can be reduced at the same time."
A 30% reduction in cycle time, a construction period of three to eight months, and costs of tens of millions to forty million US dollars.
Graf wrote three lines in his notebook.
"However, relying solely on extrapolation and calculation is far from sufficient; the system needs to be calibrated based on real production line data. The more data sources integrated, the higher the prediction accuracy. We propose a long-term value cooperation model: partners share actual production line measurement data to continuously optimize the system's predictive capabilities, and all participating companies can share the benefits brought by the improved accuracy."
This paragraph was added by Zhou Zhiyuan. The simulation system is the core capability, and the actual measurement data from the production line is the basis for calculation. The combination of the two constitutes a reliable commercial service.
After Su Chen finished explaining everything, he closed his laptop.
The entire process took fifty minutes, down to the second.
"Does anyone have any questions?" he asked.
The meeting room fell silent for three seconds.
Graf then raised his hand.
"Dr. Su, I would like to raise a technical question regarding production line simulation." His voice was deep.
"Speaking."
"If I provide hypothetical configuration parameters for a 400mm production line, can your system calculate the corresponding yield range?"
On the right side of the table, Gao Chaoyang subconsciously straightened his back. This was a question with a probing nature.
Su Chen turned his head to look at Lin Wei, who nodded slightly to indicate that it was feasible.
"Okay," Su Chen replied.
"Theoretically, the system can calculate the yield range of any size MEMS production line configuration, including 400mm production lines. However, the final accuracy depends on whether the production line configuration parameters fall within the range of parameters that have been verified."
What if the parameters exceed the verified range?
"The system will still output the inference results, but the confidence interval will be expanded accordingly, and it will clearly indicate that the result belongs to extrapolation calculation, rather than interpolation calculation within the interval."
Graf nodded and continued to press:
"What parameters do we need to provide to complete the calculations for this hypothetical 400mm production line?"
This question contains hidden considerations. The requirement to list the input parameters is essentially a test of the simulation system's completeness. If Su Chen lists parameters that are too brief, it indicates the simulation is only a rough scenario model; if the parameters are complex and detached from reality, it means the system exists only in theory and cannot be implemented.
Su Chen reopened his laptop and pulled up an additional document—not the content of the presentation slides, but a supplementary document he had prepared in advance.
The appendix contains a complete parameter table, totaling thirty-six items: twelve sub-parameters for deposition temperature gradient, nine for etching pressure distribution, six for photolithography alignment tolerance, and nine for material characteristic coefficients.
"The above are all the input variables. The output includes the yield distribution curve for the entire operating range, plus three diagnostic indicators: thermal stability coefficient, dimensional consistency factor, and batch-to-batch fluctuation prediction value."
Graf carefully examined the form for thirty seconds.
Then she looked up, first at Stein, then at Su Chen.
"We are currently developing a 400mm pilot production line internally, equipped with our own yield calculation model. We wonder if you would be willing to complete the calculations based on the production line configuration parameters we provide, and then compare and verify them with our internal simulation results?"
These words were both a question and an invitation to collaborate on testing.
Su Chen nodded in agreement: "Okay. Send us the configuration parameters, and we'll deliver the calculation report within forty-eight hours."
"Forty-eight hours." Graf repeated, confirming the time limit.
"That's right."
On the right side of the table, Jiang Mingyuan took out a paper document from his pocket. He had prepared a draft confidentiality agreement in case the other party's request went beyond the scope of academic exchange. But Lin Wei slightly raised her chin, indicating that it was not necessary to use it for the time being.
The primary goal at this stage is not to sign confidentiality agreements, but to let Bosch see the actual test comparison results firsthand.
"We will sign a confidentiality agreement before exchanging parameters, but the calculation report will still be delivered within the agreed time limit," Lin Wei added.
Stein nodded: "We agree."
Graf added, "I'll process the configuration table, converting the core sensitive parameters into proportional, desensitized values. This model's calculations aren't affected by the absolute numerical scale, right?"
"It's entirely feasible," Su Chen replied. "As long as the relative parameter ratios are preserved intact, the calculation results will be valid."
In just five minutes, a cross-enterprise joint verification test was finalized.
Stein looked at Meyer, who nodded slightly in agreement. This was an unexpected step forward beyond the initial technical exchange, meaning that Bosch intended to fully understand the capabilities of this model at this stage.
"Who has a question next?" Lin Wei interjected at the opportune moment, proactively moving on to the next topic. She deliberately avoided Graf's continuous follow-up questions, allowing the exchange to cover more dimensions and preventing the entire conversation from focusing solely on a single technical point.
Meyer then asked, "Dr. Su, regarding the development direction of digital twins, in your plan, is the third-order model the core computing engine of the industrial digital twin platform, or just one of the sub-models within the multiphysics framework?"
"We should view this from two developmental stages. In the short term, within three to five years, the third-order model will run in parallel with coupled models such as fluid and electromagnetic models, serving as one of the core computational units. In the long term, as material extension protocols mature through iteration, the third-order framework is expected to become the underlying mathematical foundation for unified multiphysics simulation in the field of microelectromechanical systems."
Meyer nodded, did not ask any further questions, and wrote down three keywords in his notebook: underlying infrastructure, mathematical foundation layer, and microelectromechanical system (MEMS) application.
His positioning is clear: this is not a single theory, nor a single product, but a set of underlying infrastructure for the industry.
Finally, Stein posed the question:
"Dr. Su, regarding the materials expansion agreement, you just mentioned continuing your collaborative research and development with Mr. Yamamoto. Is this agreement still under iterative development, or has it been finalized?"
"We are still iterating and optimizing. The current version only covers three material systems. We are expanding to support more material categories."
How should related intellectual property rights be planned?
"The complete technical documentation for the agreement has been archived, and the patent application process is underway."
Stein looked at Lin Wei, whose expression remained calm and showed no extra emotion.
"Understood," Stein said.
The meeting room fell silent for three seconds.
Stein then spoke up: "The information we've gathered so far is sufficient to support moving to the next phase. I propose that at our next meeting, both sides discuss the overall framework for potential strategic cooperation. What do you all think?"
Lin Wei glanced at the clock on the wall.
Exactly one hour.
"We agree," she replied. "We'll finalize the next meeting time after Bosch completes its internal simulation and verification. I suggest we schedule it after June 1st."
A tacitly agreed-upon timeframe. June 1st marks the official online publication of the paper in *Nature Materials*, along with the simultaneous release of Yamamoto Kosuke's complete research. By then, Wei Lan's bargaining power will be further enhanced.
"After June 1st," Stein repeated to confirm, "it will be finalized then."
Lin Wei nodded: "Very good, we will wait for Bosch to send the production line configuration parameters."
The online video conference connection remained open, and Stein, Meyer, and Graff did not immediately log off and leave.
"There's one more thing," Stein added. "I saw the news this morning that your manuscript has been officially accepted by Nature Materials. Congratulations."
He didn't use the ordinary term "paper," but rather described it as a "manuscript." This subtle choice of words clearly shows that, in his eyes, this was not just an ordinary academic article, but a core research achievement that filled a gap in the field of microelectromechanical systems (MEMS).
"Thank you," Su Chen replied.
"I look forward to reading the full text after the journal is published online."
"Once the journal lifts the ban on submissions, I will send the preprint manuscript to you and Dr. Meyer simultaneously."
Stein nodded, noticing that Su Chen had specifically mentioned Dr. Meyer. This subtle gesture showed that Su Chen, in addition to technical negotiations, also paid attention to the appropriate level of tact in interpersonal communication.
The video connection has been lost.
The in-person meeting room has returned to quiet.
Gao Chaoyang let out a long sigh of relief.
"Now that everyone's gone, let's be frank," he began. "Can we really deliver the calculation results within forty-eight hours for the comparison and verification Bosch just proposed?"
Su Chen nodded: "No problem. The entire simulation system has been set up. We can start the calculation as soon as we receive the parameters. The entire double-precision floating-point calculation takes about six hours. With extra time allocated for data anonymization, cross-verification, and compiling the formal delivery report, the 48-hour time limit is more than enough."
"What should we do if our calculations differ from Bosch's internal projections by more than five percentage points?"
"That won't happen," Su Chen said confidently.
"Won't?"
"As long as the production line parameters provided by Bosch conform to the actual industrial laws, the operation of the production line will inevitably follow the thermoelastic coupling law derived from the third-order model, and the comparison deviation will be controlled within an acceptable range. The goal of this verification is to keep the deviation stable within three percentage points."
"What does it mean if the deviation exceeds three percentage points?"
"This indicates that some parameters of the Bosch production line exceed the preset verification range of the simulation system. The problem lies with Weilan needing to supplement and expand the verification dataset, not with any defects in the model itself."
Gao Chaoyang stared at Su Chen quietly for a moment.
I was about to ask, "Are you 100% sure?", but then I swallowed the question back.
"Okay, we'll start preparing for it right away," he said.
Lin Wei looked around at everyone present: "Does anyone have any other questions?"
Jiang Mingyuan raised his hand in a gesture of greeting.
"Just now, Stein asked whether the material expansion agreement was finalized. The core of his question was to probe the licensing model of this agreement and find out whether we intend to license it exclusively or open it up for sharing with others."
Jiang Mingyuan looked at Su Chen and continued his analysis:
"If Vilan chooses to exclusively license the material extension agreement to a single company, the development space for other manufacturers, including Bosch, in the industrialization of third-order models will be limited. This is the real consideration behind his question."
Lin Wei nodded.
"He was trying to gauge our attitude toward the exclusive licensing proposal."
"That's right," Jiang Mingyuan said.
