Looking at the white clouds outside the window, this is his third trip to Taiwan this year. For this trip, Cai Zhiliang still invited Professor Gu Yuande.

"Professor Gu, is there any good news from the government recently?"

Gu Yuande still has not given up. However, even though the semiconductor market is now warming up, the government still emphasizes the so-called liberal economic policy of active non-intervention and is not interested in Gu Yuande's suggestions.

Gu Yuande smiled and said: "There is no news, even the best news is not far behind."

Cai Zhiliang said: "You all know the current situation of Jinhe Dezhou Electronics. In terms of technology, it is not yet a breakthrough, and we need industry giants like you to join us."

"I don't dare to deserve the title of giant." Gu Yuande waved his hand and said, "The reason why I resigned from IBM and returned to Hong Kong to teach is because I came back to retire. Although Taiwan is not far away, forget it. I will do my best.

The earth provides some meager strength.”

"Professor Gu is too humble." Cai Zhiliang saw that Gu Yuande's tone was a little loose, and said: "In terms of DRAM technology, Japan is the most advanced now. It is estimated that it will not be long before mass production of 16m. South Korea started late, but it is the most advanced in the country.

Under the system, it is about to break through 4m technology. And Kim Ha-deok

What Zhou Electronics has just put into production is still 1m technology. You know better than me how big the gap is. I plan to set up a R&D center in Hong Kong. Please take your time and help me develop 4m and 16m DRAM technology as soon as possible so that we can

Jinhe Dezhou Electronics has a foothold in the world."

"You are very ambitious. You still want to carve a way out in the current struggle for hegemony between the United States and Japan. But I will support your ambitions." Gu Yuande stopped being pretentious and joked:

"However, my reward cannot be low."

"It's easy to talk about remuneration." Things that can be solved with money don't matter. Cai Zhiliang saw that Gu Yuande agreed, and naturally he would not be stingy with the possible benefits in the future.

Gu Yuande asked: "Has the 4m technology licensing agreement with Texas Instruments been finalized?"

"Yes, according to Liao Chengkai, Texas Instruments only has 4m technology left." Cai Zhiliang shook his head helplessly and said, "For second-hand equipment purchased from Texas Instruments factories in North America, if the yield rate can reach the level of Japan, the monthly production capacity

There will be 1 million DRAM chips. Now the market is picking up, but after the Chinese New Year, the technology will have to be updated."

"Yes, technology updates are getting faster and faster." Gu Yuande was naturally deeply touched, "However, with the current scale of Jinhe Dezhou Electronics, I do not recommend research and development of technology, but tend to expand the scale. Otherwise,

The huge amount of capital used to develop 4m technology cannot be converted into profits at the current scale. I went to Japan in 1985 and was very impressed. The monthly output of any Sony factory is more than 3 million."

Cai Zhiliang fell into deep thought. This was not the first time that Gu Yuande's concerns came to his ears. Some time ago, Liao Chengkai also mentioned it, but he didn't take it seriously at the time and didn't care. Now that Gu Yuande raised it again, he had to

No more attention.

I just waited until the plane landed without thinking about a result.

When he walked out of Taiwan Taoyuan Airport, Cai Zhiliang saw Liao Chengkai and his party.

"Just send a driver over. If you don't need to go there yourself," Cai Zhiliang said to Liao Chengkai who was picking him up at the airport.

Liao Chengkai is now also supporting others. How can he take this seriously? He said: "My home is in Taipei, and it is also my way back to the company."

"Then let's go." Cai Zhiliang took the salute from Pata and followed Liao Chengkai to the parking lot.

After leaving the airport, Liao Chengkai realized something was wrong and asked: "Where is Pata?"

"He has other things to do, don't worry about him."

Liao Chengkai was driving, Cai Zhiliang was sitting in the passenger seat, and Gu Yuande was sitting in the back seat. He said, "Professor Gu, if you are tired, lie down in the back seat for a while."

"Okay, drive slower on the road, otherwise you will get dizzy if you drive too fast." Gu Yuande warned.

"Don't worry, Professor Gu." Liao Chengkai started the car and left the parking lot, saying: "Isn't Pata your driver? Why are you avoiding me?"

"Jinhe's investment, Pata will make a front stop."

Cai Zhiliang didn't want to mention it more and asked: "If Ajie hadn't mentioned it, I wouldn't have known you were married. I never heard you say anything about it when I was in Hong Kong last month?"

Liao Chengkai sighed and said: "We are already married for the second time, so we don't join in the fun. If close relatives from both families have a meal together, they are considered married."

Originally, Liao Chengkai and Cai Zhiliang were the class beauties of the same class, but unfortunately they did not get together in the end. Therefore, Cai Zhiliang, Deng Yingjie and others sometimes asked inconveniently, but they did not expect that Liao Chengkai had remarried. It is really unpredictable.

Cai Zhiliang said: "Just wait until your child is born to make up for the money."

"That can't be too shabby." Liao Chengkai smiled, "I heard from Ajie that the four of you are doing business together?"

"Yeah, I'm going to invest in an air-conditioning factory in the north." It was originally an investment in refrigerators, but after Deng Yingjie and Xue Cheng's inspection, it was changed to air-conditioning. Cai Zhiliang had no objection: "Lao Xue's matter, Ajie will give it to you.

Mentioned it?”

Liao Chengkai said: "I've heard a little bit about it, but as I say, don't invest in any air-conditioning factory. Invest directly in Jinhe Dezhou Electronics and let Lao Xue come to Taiwan."

Cai Zhiliang said: "It's not like you don't know the situation in his family. He is the backbone of the family. He has elderly parents and younger siblings. How can he be separated? Hong Kong is adjacent to the SAR. You can leave early and come back late, so don't worry about it.

It’s his business.”

There are still some things that Cai Zhiliang didn't say. This time, Deng Ying was the leader, and it was regarded as the Deng family's property. If it was messed up by Liao Chengkai, it would be regarded as Cai Zhiliang's instruction, and he would be a different person inside and outside.

Since it was an afternoon flight, when they arrived at Hsinchu Industrial Park, the sun was almost setting, but it was still sweltering. Cai Zhiliang and Gu Yuande went directly to the hotel to rest, and did not go to the factory until the next morning.

When he walked into Li Microelectronics and introduced Cai Zhiliang to the factory conditions, it was technical director Yue Tianhua. He originally worked at the Industrial Research Institute after graduating from college. Ten years ago, he was sent to the American RCA to receive training in 3-inch wafer fabs. He has rich experience.

"Now, wafer factories around the world use etching to dig deep grooves under the surface of silicon wafers to form capacitors. What you have in your hand is a wafer that has not been etched."

Cai Zhiliang looked at the wafer in his hand. It was a piece of waste produced by Jinhe Dezhou Electronics.

"This is a workshop for plating protective layers. It uses thermal oxidation to prepare a silicon oxide layer on the n-type Si layer, and then uses chemical vapor deposition to prepare a desalination protective layer based on the oxidized protective layer..."

In Cai Zhiliang's view, what Yue Tianhua introduced was just dry technology that really didn't lift his spirits. The main reason was that he didn't understand these details.

"Since the development of deep groove etching technology, various manufacturers have different design methods. We use Texas Instruments' TTC technology, Japan's NTT's IEVC, and IBM's SPT technology..."

Cai Zhiliang could only interrupt Yue Tianhua's introduction and said: "Director Yue, you can discuss this specific technology with Professor Gu. I just want to know, what is the current yield rate?"

Yue Tianhua said: "It has just been put into production and some manufacturing parameters are still being adjusted. Currently, it can produce about 150,000 1m DRAM memory chips per month."

Yue Tianhua only mentioned the output, but did not mention the yield rate.

Cai Zhiliang calculated silently, based on the output mentioned by Yue Tianhua, and extrapolated it back, he came up with an incredible figure, and asked: "Does that mean the yield rate is only 10%?"

This is a bit serious. With a yield rate of 10%, the cost is eight times higher than in Japan, completely obliterating the advantage in labor costs.

"This is just the beginning, and it will take a while to get used to it," Liao Chengkai said. "Texas Instruments' technology still needs to be digested. Although the workers have been trained for a period of time, they have just started working and have not yet mastered various technologies.

I have told you before that we will increase the yield rate to over 40%, but we still have to wait two to three months."

"Two or three months..." Cai Zhiliang was not in the mood to continue reading. Although he had been prepared, the reality was a bit cruel. Even a 20% yield rate would be good.
