Reborn in 2010, the AI ​​in my mind is too powerful.

February 10th, Thursday, the eighth day of the Lunar New Year, was the day Chen Yiran's Shougang Wanguoyuan officially took over Shougang Electric.

Chen Yiran arrived at the gate of Shougang Wanguoyuan around 8 a.m. His father looked at the factory from the gate and said with some pride, "Keep it up! This stage is all yours, so give it your all. You're the one who will carry the torch for me at Shougang."

"Dad, you're wrong. Your reputation at Shougang is something I earned."

Mr. Chen snorted and drove away.

Chen Yiran didn't go in directly, but waited for others at the entrance. After more than ten minutes, the big shots finally arrived.

Although he already knew the situation, Chen Yiran was still very excited to see a group of nearly fifty people.

These people weren't recruited by him; they came with Qiu Ciyun, Ji Minghua, and Zhao Yuanzheng.

Qiu Ciyun brought a complete operational team, including production planning, supply chain management, factory operations management, and quality control.

Ji Minghua brought with him a team of engineers specializing in process integration, yield analysis, and device modeling—a whole technical line comprised of Hu Zhengming's students and disciples.

Zhao Yuanzheng brought four production line team leaders, three equipment maintenance engineers, and his wife.

Even Chiang Shang-yi, who has been retired for a long time, brought along Wu Chin-cheng, a retired senior photomask engineer from TSMC, and Chen Tsung-wen, a retired plant director from TSMC.

In addition, after Shougang Nippon Electric reassigned 787 employees, 295 front-line backbone personnel remained, including front-end technicians, back-end packaging workers, and process engineers.

Shougang Wanguoyuan has already built a complete framework for a wafer fab, with everything from senior management to processes to production lines, all of which have been worked on in large factories.

Chen Yiran thought to himself: "Jasmine is awesome! It's a great idea to poach people from the top management of SMIC!"

【<(￣︶￣)＞ It's not entirely my doing; your influence is also very strong. You attracted these four people, who brought their own food to join you!】

Chen Yiran shook hands with the bigwigs one by one, and then had the factory's HR personnel take a group photo of everyone next to the new factory sign at the entrance.

Chen Yiran doesn't really like doing these things, but he has a specific purpose today.

Chiang Shang-yi and his party of three old men had only said they wanted to come and visit; they hadn't yet agreed to join the company.

Chen Yiran planned to use this to forcefully establish that they had already started working.

I took a gamble, and a few old men were too embarrassed to come and said they didn't want to work anymore.

Afterwards, people from various business lines began to conduct on-site inspections of the various factories. Several senior executives also personally went to key locations to check the actual situation of the factories.

Chen Yiran felt that following any of them would be appropriate, which made it seem like she didn't value the others enough, so she simply went to the office to wait.

Around noon, everyone grabbed a quick bite in the cafeteria. Chen Yiran then led the leadership team into the conference room to discuss the company's next steps and overall strategy.

Chen Yiran sat at the head of the table and began with personnel appointments: "Today is the first management meeting of Shougang Wanguoyuan in this room. As the chairman, I will first determine a few positions."

Qiu Ciyun was appointed as CEO to oversee the overall operations.

Ji Minghua was appointed as CTO, in charge of technology direction and R&D.

Mr. Jiang, you said you're getting old and don't want too many burdens, so how about we appoint you as the Chief Engineer of Advanced Packaging, in charge of packaging roadmap and 12-inch production line layout planning?

Wu Jincheng, you were the Director of the Photomask Engineering Department, in charge of mask data, OPC correction, and the photomask workshop.

Chen Zongwen, as the plant director, you are in charge of cleanroom construction, ultrapure water, special gases, and power systems.

Zhao Yuanzheng, you'll be the manufacturing director, overseeing daily operations and production line shifts.

Everyone nodded and accepted the appointment. Jiang Shangyi hesitated for only two seconds before nodding and accepting it when he saw that Wu Jincheng and Chen Zongwen, who had come with him, had also agreed to the appointment.

After the personnel decisions were finalized, CEO Qiu Ciyun immediately got to work and, at Chen Yiran's prompting, began to chair the meeting.

He opened the notes he had taken in the workshop that morning and began to explain: "We roughly checked the status of the equipment in the previous process. The accuracy of the three Nikon stepper machines in the lithography area has dropped to more than 0.5 micrometers, so they can't do proper contract manufacturing, but they can still be used for mask making."

The maintenance records for the Lam 4400 in the etching area are fairly well preserved, and the gas pipeline interface seals are still intact. However, the spare parts inventory is only enough for about a dozen months. The two Varian ion implantation units are even older; it's uncertain whether they can still operate.

Zhao Yuanzheng raised his hand and said, "We've checked it, it should be fine."

Qiu Ciyun turned the page: "Okay, let's get started. The Japanese-made chip mounters and wire bonding machines in the packaging area are maintained much better than those in the previous processes. We can still produce 200 million QFP packages a year."

Ji Minghua took over the conversation, opened his notebook, and projected a process route diagram onto the screen.

"I've discussed the short-term positioning of the 6-inch line with Mr. Qiu. We're no longer doing general logic foundry work; the prices there have already been driven down. We'll focus on specialized processes: BCD power devices are one piece, MEMS sensors are another, and analog mixed-signal front-ends are yet another."

0.35 micrometers is perfectly adequate for these three types of products, and the profit margin is much higher than that of foundry logic chips. The 6-inch line doesn't need to be fully utilized; keep 8,000 to 10,000 wafers per month in reserve, and use the remaining time for tape-out verification and process training.

Chiu Tzu-yun added, "If the 6-inch production line can maintain a stable production rate of 8,000 wafers per month for special processes, the annual revenue can reach over 200 million, with a net profit of about 30 to 40 million. It's not a lot, but at least we won't have to lose money on it anymore."

Chen Yiran leaned back in his chair and thought for a moment. This number was already much better than he had previously estimated.

Moreover, although he didn't know the specific figures in his previous life, he still understood the general trend. The next decade or so would likely see very profitable ventures in various small semiconductors; after all, everything would contain chips.

Jiang Shangyi finally spoke at this moment. He hadn't said much since he came in, and now he picked up his teacup.

"Six inches is fine, but 12 inches is what we're aiming for, right? This morning, Chen Zongwen and I took a close look at the cleanroom and power system. The return air duct is a design standard from the 6s."

However, to build a 12-inch line, the cleanliness level must be at least ISO 3. The current return air system needs to be completely redone. The ultrapure water piping is in good condition, made of 316L stainless steel; only the valves and filters need to be replaced. The special gas piping uses semiconductor-grade welding standards, so this section doesn't need to be touched.

Chen Zongwen opened a kraft paper notebook next to him, on which was a simple drawing he had made that morning.

"The transformer redundancy in the power distribution room is indeed very large, even a bit outrageous, but the entire power distribution cabinet and UPS need to be replaced. The current power distribution cabinet is from 1995, and its overload protection no longer meets the voltage stability requirements of 12-inch equipment."

Zhao Yuanzheng asked, "How long does it take to renovate a cleanroom?"

"One year, at least one year. The return air system takes six months to disassemble and reinstall. Replacing all the HEPA filters will take two months. Add in the linkage debugging and particle detection, let's conservatively say a year."

Chen Yiran brought up the matter he was concerned about: "Regarding the new equipment, please make a list of all the new equipment we need to buy."

Ji Minghua moved forward a bit and said, "Indeed, the equipment procurement needs to start now. The delivery time for lithography machines is too long. ASML's delivery cycle for immersion DUV is generally twelve to eighteen months now. The lithography machines should arrive just as the cleanroom renovation is completed."

Qiu Ciyun picked up the paper in front of him. It was a list of equipment specifications.

"I've listed the equipment for the entire 12-inch line. For the photolithography section, there are five ASML NXT immersion DUV machines, model 1950i. They are paired with five TEL CLEAN TRACK coating and developing tracks. There is also a set of photomask inspection equipment, which is the largest single expense."

Twelve etching units, Lam 2300 series. Four for silicon etching, four for dielectric etching, and four for metal etching. Thin film deposition: four for PECVD, two for LPCVD, three for PVD, and two for ALD, all using AMAT.

Five ion implantation machines: two high-current, two medium-current, and one high-energy. Both AMAT and Axcelis are acceptable, depending on lead time. Six CMP polishing machines: AMAT's Mirra series.

On the measurement side, there are two KLA bright-field and two dark-field defect detectors, two film thickness measurement units, and two CD linewidth measurement units. Four cleaning units are used, employing DNS wet cleaning stations. Three RTP rapid heat treatment units and four furnace tube units are used for heat treatment.

The meeting room was quiet for a moment before Qiu Ciyun placed the paper in his hand on the table.

Ji Minghua said with a hint of admiration, "The entire 12-inch line, including the photolithography part, costs about 250 to 300 million US dollars. Including the complete supporting facilities, the total is 1 billion to 1.2 billion US dollars, and that's a conservative estimate. Chairman, for someone your age to make such an investment is truly impressive."

Chen Yiran ignored the price issue. He looked at the dizzying bill and asked a question: "Among these devices, which parts are most likely to wear out and need to be replaced? Please list them all for me."
