Super Copy of Great Power Technology

This memory test report illustrates at least two issues. One is that the third-generation memory chip with a new architecture developed by Qiao Ruida has no problems in design, and its performance reaches or even exceeds the level of similar foreign products; the other is that, This 7nm chip production line using EUV lithography machines can produce qualified products, but the current yield rate is relatively low. However, this is not a problem for Rockchip's technical staff. The overseas returnee team represented by Lin Mengsong and the Peking University team represented by Academician Wang all have rich experience in optimizing chip production lines and improving yield rates. The two teams cooperate with each other and work together to definitely increase the yield rate of this 7nm chip production line in a short time.

While Qiao Ruida and others were installing and debugging 7nm chip production lines and testing and producing memory chips, a group of technicians and equipment installation engineers were busy installing and debugging multiple 28nm chip production lines. Since the equipment used in these 28nm production lines is exactly the same as the equipment on the two chip production lines in Reda Electronics Factory, many technicians who have worked and been trained in Reda Electronics Factory are very familiar with this production line. During the equipment installation and debugging process, a lot of time is saved.

Another half month later, the first phase of the Rockchip wafer foundry project was completed and put into production, involving a total of 17 28nm chip production lines, one 7nm chip production line, and five supporting test and packaging production lines. If the firepower is fully activated and all production lines operate 24 hours a day, Rockchip Wafer Factory can process tens of thousands of wafers per day and produce more than one million chips. However, the current Rockchip wafer fab has just been established. The yield rate of the production line is not high, there is a serious shortage of manpower, and the production capacity is very limited. All of this takes a lot of time to polish. It takes time to recruit and train talents. It also takes time to improve the production line yield rate. It also takes time to build a reputation in the chip foundry field and attract more business.

A major event like the completion and commissioning of the first phase of Rockchip's wafer fab naturally needs to be publicized with great fanfare. In order to build a reputation, attract chip foundry business, and also highlight the local government's achievements in attracting investment, Qiao Ruida decided to hold a press conference for the completion and commissioning of the Rockchip wafer factory. The host of this press conference was naturally Morris, CEO of Shengshi Investment Company. After all, in name, Shengshi Investment was the largest investor in Rockchip, accounting for the majority of the shares.

Qiao Ruida made a phone call and called Morris, who was far away in Hong Kong, to Decheng City, and then handed over all the preparations for the press conference to him. As for Qiao Ruida herself, she has returned to her family and enjoys shopping and walking her dog with her mother Yao Miaozhi every day, or visiting stores and repairing her mobile phone with her father Qiao Jingkang. Before the weekend, I could still find time to tutor my sister Qiao Ruixue with her homework.

My younger sister, Qiao Ruixue, is a sophomore in high school this year. She is a beautiful academic. After entering high school, she has ranked first in her grade for two consecutive years. . My sister has such good academic performance, even if she gets tutoring, her improvement will be limited. However, Qiao Ruida is a cheater. In ten years' time, next year's college entrance examination papers will be available on the Internet. It is difficult to reveal the real questions of the college entrance examination to my sister, but similar question types can be mixed into the usual tutoring content and explained to my sister in detail. Even the college entrance examination essay questions were mixed among dozens of similar essay questions and were given to Qiao Ruixue for her daily practice. With this kind of guidance, on the eve of the college entrance examination next year, I will provide my sister with a few sets of mock test papers with added materials. I dare not say that it will be very simple to help her improve her college entrance examination score by a few points.

Du Qingqing had already returned to Peking University at the end of the May Day holiday. Now the two are separated in two places and can only meet online at night. The current version of WeChat does not support the video call function. You can only use the PC version of QQ. Through the video chat function, you can meet the person in the distance to relieve the pain of lovesickness. The laptops used by Qiao Ruida and Du Qingqing were equipped with 130W pixel cameras, and the QQ software compressed them during transmission. The final image displayed on the other party's computer was so blurry that it was impossible to see it. This makes Qiao Ruida extremely nostalgic for the later WeChat video calling function. The ultra-high pixels of the mobile phone, coupled with the basically lossless compression and transmission technology, the images presented are at least dozens of times clearer than now, and they are not much different from talking face to face. .

A week later, the press conference for the completion and commissioning of the Rockchip wafer fab was held in the No. 1 canteen of the Rockchip wafer fab. Present at the press conference were executives from Rockchip Fab, relevant leaders of Decheng City, and many media reporters from Decheng City and Bei Ha Province. Even CCTV sent a reporter and a filming team. This shows that all parties attach great importance to the start-up of Rockchip wafer fab.

As one of the important investors of the project, Qiao Ruida took a seat on the rostrum. Sitting on the rostrum with him were Morris, CEO of Shengshi Investment Company, Peng Boyu, mayor of Decheng City, Wei Changhe, director of Decheng City Investment Promotion Bureau, Lin Mengsong, chief engineer of Rockchip Wafer Fab, and Rockchip Wafer Fab. Factory director and Rockchip CEO Luo Yuankai. The last one, Luo Yuankai, is a foundry management and management talent that Morris hired from Hong Kong. He just returned to China last week and came to work in Decheng City. Luo Yuankai is a Hong Kong native who studied at Stanford. He received a master's degree in integrated circuits and a doctorate in management. After graduation, he joined AMD and has been engaged in fab management. Later, AMD split its wafer processing business. Luo Yuankai followed the team and joined GlobalFoundries. The highest position he held was the director of a wafer factory. This is also a gold-collar position in China, with annual salary and bonuses. , at least hundreds of thousands of dollars. I don’t know what kind of ecstasy Morris poured into Luo Yuankai, causing him to voluntarily give up all positions at GlobalFoundries, resolutely return to China, and join the newly built Rockchip wafer fab.

The press conference was hosted by Luo Yuankai. He stood up with a microphone and said: "Dear colleagues, leaders, and journalists, good morning! Let me introduce myself first. I am the director of Rockchip Wafer Fab. Luo Yuankai, CEO of Rockchip. Our factory was established and started construction in August last year. At that time, there were two main investors, one was Shengshi Investment Company from Hong Kong and the other was Ruida Technology Company from Beijing. The two companies invested a total of We have spent RMB 700 billion and plan to build a large-scale wafer foundry in Decheng City that can process 3 wafers per day." (End of this chapter)
