"Great!

69%！

It simply doesn't get any better than this!!"

Kang Yaoxiang and other engineers gathered around Hu Yiting and said.

A world's first, using a revolutionary design, reaching the world's most cutting-edge line width and single-chip capacity, with exclusive confidential production process and process parameters, the first industrial tape-out can achieve 69% assembly line yield rate!

Everyone knows how hard it is!

In the semiconductor manufacturing industry, in order to produce the most advanced chips, sometimes, a yield rate of 10% is acceptable.

For example, in the mid-70s, IBM designed two special chips and manufactured them in its own wafer factory, with a yield rate of only 10%, so it felt that the cost was too high, so it outsourced to Texas Instruments, and Deyi happily took the order, and the yield rate turned out to be 0! Yes, all of them were unqualified! IBM fainted angrily and almost sued Deyi.

In the semiconductor industry, it does not mean that chips can be designed, laboratories can be made regardless of cost, and well-equipped wafer factories can industrialize and manufacture qualified products in large quantities.

If you don't master the key process technology and give you qualified equipment, you won't be able to produce cutting-edge chips.

The so-called advanced manufacturing industry is advanced in the cutting-edge technology and process parameters involved in the manufacturing process, and the so-called advanced is to master the core technology that others have not mastered.

is also for Apple OEM A9 processor, TSMC's yield rate is more than half, Samsung has lost face, the yield rate is lower than 30%, and there are serious defects in leakage control, resulting in the same Apple A9 processor, Samsung's foundry chip, the efficiency is worse than TSMC's, repeated overheating, crash restart, and excessive power consumption. This left Apple with a lot of headaches, and had to secretly replace a large number of customers with serious problems, and spend a lot of public relations money to cover up the news and maintain the company's brand image.

Therefore, it is a true miracle that Chongguang's world-first MLC flash memory can complete the acceptance of industrial processes with a yield rate of 69%, and the engineers and scientists who are not allowed to participate in the project are excited.

In a group of excited colleagues, Hu Yiting was calmer.

He knew that today's achievements were not easy to come by, and it was the result of the concerted efforts of many engineers, so he said that Kang Yaoxiang and Jiang Yunshun were busy now without touching the ground, and after Jiang Yunshun was transferred to Puhai from the northern capital, he plunged into the wafer factory, eating and living without leaving the factory, and the famous bustling commercial streets in Puhai did not have time to visit once.

Not to mention Kang Yaoxiang, in Hu Yiting's heart, he is the leader of the Chongguang chip manufacturing business department.

After coming to Puhai, Hu Yiting participated in several production summary meetings of the wafer factory, at which Hu Yiting basically did not speak, and always sat quietly at one end of the long table in the conference room, watching Kang Yaoxiang transform into an irritable president with an expressionless face.

"Don't tell me so much! I'll ask you why the gluing machine can't keep up with the speed of the lithography machine!

How's the ion implanter running today?

How much film does the grinder produce today?

What is the effect of the trial of the new domestic target of the Hu Jian Institute of Physics?

Teleporter No. 3 crashed last night, how is it running after the maintenance is returned?

Inspect the cleaning process of your project, and you can explain to me the data that comes out!

I don't know how to scrap the last pot of 30 pieces! If the factory is like your department, the investment of 7 or 8 billion yuan will be thrown into the Huangpu River! If you break this machine, you can't afford to pay for the shooting!

…………”

No wonder when he was in Huachuang before, Qin Zhenfei said that manufacturing is the most troublesome business, Hu Yiting participated in several daily routine summary meetings of No. 1 FAB, and finally knew why Kang Yaoxiang would now change from gentle and elegant to a murderous and fiery state, and there was no scolding in every meeting.

Because there are too many newcomers, and Chongguang has no foundation in the process industry at all, if a large number of engineers such as experienced Kang Yaoxiang were not poached from various units such as the Institute of Microelectronics with high salaries, it is difficult to imagine that Chongguang's No. 1 FAB would have such a fast construction and production speed.

Hu Yiting reviewed Kang Yaoxiang's carefully formulated factory process in detail, affirmed it, and made only a few modifications.

In Chongguang No. 1 FAB Puhai wafer factory, each process has a special team in charge, similar to the department of the enterprise, and like the section in the factory, twelve departments, each less than seven or eight people, more than forty or fifty people, when the wafer factory is running, a wafer needs hundreds of processes to process, and the responsible department of each section must summarize the data in real time, and report the data of the previous period through the intranet, so that the chief engineer on duty at the top of the wafer factory can query and monitor the production status at any time.

In the previous trial runs, any flaws in the process flow would lead to the department manager in charge of the relevant department being scolded by Kang Yaoxiang, even Jiang Yunshun, an employee who is close to Hu Yiting, was criticized by Kang Yaoxiang several times.

In Jiang Yunshun's words, every day's summary meeting is a criticism meeting, unless the next tape-out is successful, Mr. Kang can explode if he encounters a little spark.

Now that the results are out, Hu Yiting wants to thank Kang Yaoxiang the most, without his seriousness and ferocity, there would be no good results today, cutting-edge chip manufacturing industry, a factory invests tens or even tens of billions, all kinds of sky-high equipment, scrapping a furnace of goods is tens of thousands of dollars wasted, the work here does not tolerate any mistakes, but each shift is as long as 12 hours, and the nature is boring.

Hu Yiting thought about it for a while, and said to Kang Yaoxiang with a smile: "Mr. Kang, you can arrange for everyone to give a project bonus according to their performance during this time, and the total amount will be set within three million." ”

Kang Yaoxiang now felt a sense of relief, looked at Hu Yiting and said briskly: "Okay!"

"In addition, on the side of the office building, the canteen should be more abundant, let the logistics department get some snacks from the north and south of the world, let them operate and open the store, and give them a guaranteed profit, if the monthly profit is not enough, we will make up the difference for the owner. There are coffee shops and dessert shops, hot pot restaurants and barbecue restaurants, all of which are set up, and the owner can not be found for the time being, so the company will operate temporarily. ”

Kang Yaoxiang smiled: "Am I putting too much mental pressure on them during this time?"

"Hehe, you scold like this every day, you have to make people happy to eat. ”

Kang Yaoxiang said with a smile: "I'll arrange it for tonight's meeting." Well...... Mr. Hu, will you leave tomorrow?"

"Well, go to Luzhou to talk to people about legal matters, and then go to Hong Kong, Zhu Xiaoqiao and I are together, do you have anything to bring?"

"Puhai can't buy anything, I won't trouble you, Zhang Xiang really wants to go over there, I mentioned it to me before, saying that the whole family will go once after returning this year, hehe, Mr. Hu, you said there is something fun. ”

"Ha, you have to ask Wang Lili, she has been there the most, and this is the first time for me. Hu Yiting snorted.

This time, he went to Hong Kong mainly to open a securities account, and then meet with the leaders of the asset management department of Bank of China Hong Kong to ensure the safety of the operation of the custodian funds.
