Returning to his senior year of high school, he went all in and made billions by buying at the botto

Chen Mo walked out of the office building and made a phone call to Xu Qing.

"Qingyan will need to travel between Tsinghua University and Financial Street every day for the next two weeks."

"Arrange a discreet car and find a female driver to pick you up and drop you off."

"Security should only cover the outer perimeter, not enter the office area, and should not interfere with her life at school."

Xu Qing quickly understood his request.

"clear."

"One driver will be transferred from the Women's Safety Team. He will be waiting outside the Zijing Apartment at 7:40 in the morning, and the schedule will be adjusted according to the preparation team's off-get off work time in the evening."

"I will send Ms. Su the information about the driver, vehicle, and emergency contact."

"Let's arrange it this way."

Chen Mo did not add anything further.

After that truck attack, he found it hard to entrust the safety of those around him entirely to luck.

After ending the call, the vehicle drove back to Tsinghua University along the Fourth Ring Road.

……

Tsinghua-Jiamusi Microelectronics Joint Research Center.

There are only six days left until the final layout of the first-generation heterogeneous verification chip is finalized.

Security at the entrance to the laboratory building has been raised again.

Work permits that originally allowed access to multiple areas have had their permissions redefined.

External suppliers, equipment engineers, and contract manufacturing personnel must be accompanied by Qingjia internal staff when entering different floors.

Each printed material has a unique number.

Obsolete drawings must be disposed of in the presence of two witnesses.

The underground archives are completely cut off from external networks, retaining only censored offline terminals.

Chen Mo completed two identity verifications before entering the core design area.

At the end of the corridor, a large screen displays the overall progress of the final sprint.

The interfaces between the control core, storage core, and computing core have been frozen.

The intermediate layer wiring has completed its final round of adjustments.

The basic scheduling software has successfully run its third version on a programmable hardware platform.

The wafer edge warpage compensation parameters previously proposed by Chen Jing have also been incorporated into the packaging process documentation.

There are still seventeen issues that have not been closed.

If any step is not handled properly, months of hard work could turn into a batch of unusable silicon wafers.

Silicon photonic interconnects and microchannel liquid cooling were not forcibly crammed into the first-generation main chip.

Both routes continue to be validated using independent prototypes, with the main architecture retaining only the interfaces.

Gu Shaoting ultimately adopted the safest option.

First, enable the first-generation core to recognize, communicate, and operate collaboratively, and then consider incorporating more advanced technologies into the same system.

When Chen Mo entered the conference room, Wu Huaqiang was having a video conference with engineers from the contract manufacturer.

Three different versions of process documents were laid out on the table.

"The metal spacing of the seventh layer has been rechecked according to your latest rules."

"The problem is not in the core area, but at the junction of the test structure and the cutting channel."

"Send over the revised rule sheet this afternoon, and the final round of verification must be completed tonight."

Wu Huaqiang checked more than a dozen items on the screen.

He only noticed Chen Mo after the meeting ended.

"When did you arrive?"

"Just arrived."

"Please sit down."

Wu Huaqiang picked up the teacup on the table, took a sip, and realized it was already cold.

He frowned, but still swallowed it down.

"How is the situation now?" Chen Mo asked.

"The general direction is fine."

Wu Huaqiang handed him the master sheet.

"The rest are all details."

Whether the chip can be successfully produced in the end depends on these details.

"Will the funds be frozen on the 25th as scheduled?"

"As long as the OEM rules don't change again, it's fine."

After Wu Huaqiang finished answering, the phone on the table rang again.

He only had time to wave to Chen Mo before quickly leaving the conference room with the documents.

Chen Mo sat there for less than two minutes before seeing Gu Shaoting pass by from the other end of the corridor.

The elderly man listened to the reports from the three experts as he walked.

The final review of the National Integrated Circuit Industry Investment Fund, contract manufacturing, packaging, computer systems, and storage all fell to him.

Some experts advocate eliminating some redundant channels to free up more space for the main chip.

Some insist on retaining the bypass structure, preferring to sacrifice the peak performance of the first generation in order to improve the availability of the packaged product.

Gu Shaoting did not make a decision in the corridor.

"Calculate both possible outcomes and the worst-case scenario."

"The meeting will be at 4 PM."

"Whoever insists on their own plan should explain clearly what will happen if they fail."

He only noticed Chen Mo after he finished speaking.

"You're here?"

"Um."

"Perfect timing, we'll both be attending the review at four o'clock."

Gu Shaoting did not stop.

"I'll go check on the packaging team first."

The group quickly disappeared around the corner of the corridor.

Chen Mo stood alone for a moment.

The laboratory was more rigorous than he had imagined.

The initial architecture document set the direction.

Over the past few months, hundreds of researchers and engineers have broken it down into countless specific problems that can be calculated, verified, and manufactured.

Today, Chen Mo's memories of the future can help him make decisions, but they cannot replace an engineer in performing a wiring inspection, nor can they measure the deformation of materials after hundreds of thermal cycles for the packaging team.

For the first time, he clearly felt that once a complex technology truly enters the engineering phase, the role that an individual can play is ultimately limited.

Even if this person knows where the destination is.

Chen Mo left the conference room and went to the failure analysis area.

He spotted Chen Jing through the glass at a glance.

She was wearing a lab coat, her long hair casually tied back, and protective goggles perched on her nose, arguing with two packaging engineers about a set of thermal stress data.

The desktop is covered with failure distribution diagrams in different areas.

On the screen, the red markers at the edge of the wafer were divided into dozens of groups.

"We cannot use average temperature alone."

Chen Jing circled an area on the map with a pen.

"The heating rate, duration, and cooling sequence are all different."

"Even at the same peak temperature of 120 degrees Celsius, the stress experienced by the materials is completely different."

The engineer asked, "If we further divide the time window, the testing workload will at least double."

"Then increase it."

Chen Jing said.

"Saving half a day now, but then discovering that the entire batch of samples failed in the same location after packaging, means losing several months."

After she finished speaking, she turned around and then noticed Chen Mo standing outside the glass.

Chen Jing pushed open the door and came out.

"What brings you here?"

"I came to see if you need any help."

"need."

Chen Jing answered without any politeness.

Chen Mo raised an eyebrow.

"Speak."

Order me some decent takeout.

Chen Jing pointed to the corner of the table.

There were two empty coffee cups and an opened pack of soda crackers.

"What else?"

"That's all."

Chen Jing put her goggles back on.

"You can't help with the technical stuff right now."

"Remember not to bring up any new ideas during the 4 PM meeting."

"What we fear most right now is someone like you who suddenly gains new abilities."

Chen Mo was speechless for a moment after hearing what she said.

"Don't worry, we won't add any this time."

"That's fine then."

Chen Jing turned back to the screen and continued to check the data with the engineer.

After leaving the failure analysis area, he found Wen Zhixia in the project management office.

In front of Wen Zhixia were three telephones and a thick schedule.

She had just finished a call with the Dutch equipment team and was now confirming the arrival time of a batch of test materials.

"The high-stress test wafers from France have completed customs procedures and will be delivered tomorrow morning."

"The packaging plant will keep one engineering line open during the Spring Festival, but only gives Ching Chia a three-day window."

"The visas of the two equipment engineers expire on the 28th, and they must complete the operation training and parameter filing before leaving the country."

"All external personnel must re-sign confidentiality documents before entering the core area; the version issued by the legal department this afternoon shall prevail."

She finished explaining everything before picking up her water glass and taking a sip.

Chen Mo stood at the door for a long time.

Wen Zhixia noticed his gaze and looked up.

When she first joined Qingjia, she mostly accompanied Chen Jing and was also responsible for the information exchange between Jia Ning and the laboratory.

Today, equipment, materials, contracts, external teams, contract manufacturing milestones, and technology transfer processes have all been incorporated into her timeline.

"When did you get back?"

A hint of surprise flashed in Wen Zhixia's eyes.

"We just arrived."

Chen Mo went over and refilled her empty water glass.

Have you had lunch?

"I ate a little."

"How much is one point?"

"Half a boxed meal."

"You and my sister are quite alike in this respect."

Wen Zhixia was a little embarrassed.

"I have a lot to do today."

Chen Mo did not continue to blame him.

He sent a message to Xu Qing, asking the family office to arrange regular meals and nighttime medical shifts.

……

For the next few days, Chen Mo stayed in Qingjia almost every day.

I participated in the version review this morning.

In the afternoon, I contacted the contract manufacturer and the packaging company.

In the evening, I confirmed the issue of closing that day and the arrangements for the next day with Gu Shaoting and Wu Huaqiang.

The most suitable window for 28-nanometer foundry services in China has already been locked in.

The mask data will be delivered via a separate encrypted link after the layout is frozen.

To avoid any unexpected issues during the first round of manufacturing, Ching Chia also reserved a second set of mask revision windows and paid the contract manufacturer the full priority scheduling fee.

The two leading packaging and testing companies are responsible for interposer layer, high-density interconnect and finished product testing, respectively.

One company is responsible for the main process, while the other retains the verification and backup capabilities.

Chen Mo also procured enough substrates, test carriers, and key consumables in advance through Jianing Holdings to complete three rounds of engineering verification.

..............

On the evening of January 23rd.

The number of issues that remain unresolved in the core design area has been reduced from seventeen to four.

There are only 48 hours left until the final freeze.

When Chen Mo left the conference room, it was nearly eleven o'clock.

Neither Chen Jing nor Wen Zhixia had any plans to return to Wanliu Academy.

The three of them were eating hot porridge and a few light side dishes that had just been delivered by the family office in the small restaurant on the first floor of the laboratory building.

"Your parents asked when you're coming back to Jiangcheng."

Chen Mo looked at Chen Jing.

"I'm not going back this year."

Chen Jing lowered her head and took a sip of porridge.

"Freezing the territory is only the first step."

"Following this are the OEM interface, packaging process confirmation, and testing platform."

"Before the wafers return, I need to prepare the failure database and test rules."

Have you talked to your parents?

"I called yesterday."

Chen Jing said.

"Mom initially disagreed, but after hearing that Academician Gu and Professor Wu were not taking a break, she stopped trying to persuade them."

Chen Mo turned to look at Wen Zhixia.

"And you?"

Wen Zhixia put down her chopsticks.

"I will stay in Qingjia too."

"During the Spring Festival, the schedules of the contract manufacturers, packaging plants, and European equipment teams are all different."

"The entry and exit of external personnel, the transportation of materials, the handover of versions, and the approval of confidentiality must be monitored by someone."

"My parents have already made arrangements."

She paused.

"We can have our New Year's Eve dinner earlier this year."

Chen Mo looked at the two women but did not try to persuade them to go home.

This chip is extremely important to Ching Chia, to the domestic semiconductor industry, and to each and every one of them.

When it comes to the final step, no one wants to leave.

After having a late-night snack, the three of them walked out of the restaurant together.

The Tsinghua Garden outside the window has fallen asleep.

In the distance, the lights in the student dormitories were mostly off, and only occasionally did a winter break duty bus drive by on campus.

The Qingjia Experimental Building, however, remained brightly lit.

One floor, three floors, five floors.

Behind every lit window, someone is counting down to the same date.

January 25th.

The final map is frozen.

From that day onward, all designs written on screens, drawings, and simulation models will, for the first time, be realized on real silicon wafers.
