Of course, the existing integrated circuit production process can only produce some low-voltage chips, and high-power devices have many unique technical difficulties, such as the thinning process of chips, the back process, to solve these difficult processes need to be reformulated, and special process equipment is also required, and there is no experience in this area in China.

Not to mention, the thickness of IGBT chips is specific, it needs to be thinned to 200-100um, or even to 80um, now the wafer can be thinned to 175um in China, and there is no ability to do it if it is low.

The backside process includes backside ion injection, annealing activation, backside metallization and other process steps, which must be carried out at a low temperature of no more than 450°C, and the difficulty of annealing activation is no less difficult than that of the new process developed by Sinocrystal.

In terms of module packaging skills, Huayue Electronics Co., Ltd. and Zhongjing Micro control the packaging skills, but they lack experience in high-voltage module packaging skills.

Fortunately, in the past few years, Jingwei and Huayue Electronics Company have also created a group of high-end process development staff, and Ruixing Technology Company also has a certain strength in equipment, at least in production is not without strength.

The domestic company in the United States is the strongest in the design and production of IGBT chips, Yang Jie is now also asking the American company to look for experienced design staff, and now has found a few suitable R & D staff, next month these staff will return to China to enter Loongson Semiconductor Company to start this aspect of R & D and design work.

Yang Jie himself is the world's top in IC design, but there are hundreds of types of chips, and he can't be proficient in everything, what he has to do is to find the right talent to provide a good R&D environment.

The IGBT module can be used not only on fuel cell vehicles, but also for other high-power equipment, and Yang Jie will not worry about the funds he invested in the early stage.

However, now IGBT chips have developed to the fourth generation abroad, and are now developing the fifth generation, and foreign companies have formed technical patent barriers on this, but this has opened up a technical route for Yang Jie's R&D team, as long as they keep an eye on the technical routes of these foreign companies.

Moreover, now the economy of Huaxia is taking off, the market scale is becoming larger and larger, and the independent research and development of IGBT chips will enter other subdivisions after meeting their own needs, Yang Jie is not worried about the market prospects.

"In that case, you should be able to launch fuel cell buses in two or three years?" Xu Youlun asked in surprise.

"Not much. Yang Jie nodded.

Yang Jie had to sigh at the diligence and hard work of these domestic R&D staff, once the company determined the goal, these skilled staff were all twisted into a rope, working overtime and working hard, and those foreign engineers also felt a lot of pressure.

Xu Youlun also sighed: "I couldn't imagine that Scania Group Company would be willing to come up with skills to cooperate with you." ”

"I don't have any hard skills at hand, and others don't want to play with you!" Yang Jie said with a smile.

"Now Huaxing Science and Technology Group Company is involved in a wide range of industries, involving automobiles, integrated circuit design and production, network companies, communications, equipment production, you have to govern such a grand company is also very stressful, right?"

"There are professional staff to do corporate governance, and what I want to do is to formulate a fair distribution plan, establish a reliable data analysis system, find the skills and projects that the company needs, and revitalize domestic talents or R&D projects. ”

"In the past, the company had to compete for talents with Huatai and Fuxing domestic companies at high prices, but now with this data analysis system, the company no longer needs to spend money with them to grab people, and with this system, the evaluation of the ability of skilled staff has a very accurate evaluation, but it has saved a lot of expenses for the company. ”

Yang Jie said with a smile: "Now Huaxing Technology Group Company needs a specific ability, not a certain person, even if the excellent talent leaves, it will not have a great impact on the company, we can use this system to find people with this specific ability." ”

"I now only need to grasp the company's overall strategy will not emerge directional problems, in the past some specific technology research and development projects I still have to take the initiative, now my energy has begun to shift to some forward-looking skills. ”

While eating, there was a burst of Japanese laughter in the next room, and I heard a Japanese man say loudly in Japanese: "These Chinese people are like dogs wagging their tails and begging in front of us Japanese, didn't I take a fancy to a female secretary of She Haiping, the deputy head of the district, and the official forced this woman to follow me, and I got tired of getting tired of dumping this woman, and a police friend of this woman found me to ask for guilt, what do you guess happened later?"

"Zong Quan-kun, what's going on behind the scenes?" the other Japanese hurriedly asked.

"The head of She Haiping immediately arrested the policeman, and then came to me to apologize to me, as if he had done something wrong. This guy named Zong Quan laughed.

"These officials in Huaxia are afraid of getting into foreign disputes, so they naturally treat us as the God of Wealth. Several Japanese people burst out laughing uncontrollably.

"You are not allowed to tell her these things when Miss Mina comes! Zong Quan said.

"Isn't this Miss Mina's fiancé Takeshi Ohno?" said a Japanese man.

"Isn't she still unmarried? I've been in the United States for so long, and it's the first time I've met such a smelly woman. "Zongquan tsk tunnel.

"I heard that this Miss Mui Ne is very powerful, and the president of Fuji Heavy Industries, Aooka Chuanxiong, is very polite to her. ”

"No matter how powerful you are, you won't be at my mercy when you get to the bed!" Zong Quan said with a lewd smile.

Hearing these conversations next door, Yang Jie's face became very embarrassed, and he also knew that this Miss Mina was naturally Mina Fujita.

"Yang Shao, what's wrong?"

"Secretary Xu, do you have a deputy district chief named She Haiping?"

"It's such a person, what's wrong?"

So Yang Jie told the conversation between the Japanese next door.

"I will definitely find out this matter after I go back, if there is such a thing, he, the deputy district head, will not have to do it!" Xu Youlun said angrily.

At this time, the footsteps of several people sounded in the aisle outside, and the sound of high heels hitting the wooden floor was heard, apparently Mina Fujita had come over.

The sliding door next door was pushed open, and Zong Quan laughed and said, "Miss Mina, come and sit down!" he immediately said with great courtesy.

Yang Jie had a wicked smile on his face at this time, he glanced at Qin Ling and Gao Shuqun and said, "I know this Miss Fujita Mina, I said hello in the past." ”

"Then I, the secretary of the municipal party committee, naturally want to say hello to these Japanese guests. Xu Youlun immediately knew Yang Jie's intentions, and he also looked like a good show.

So Yang Jie and the others came to the next door and pushed open the door.

At this time, Fujita Mina was sitting at the end of the door, wearing a dark skirt, and her white and delicate face was looking at Yang Jie and the others outside the door in surprise.

Sitting next to her was a young man of twenty-seven or eighteen, with a hooked nose, thick eyebrows, and a fierce face, who was pouring wine into the feather in front of Fujita Mina!

"Who are you?" the man asked patiently and loudly.

As soon as he heard this voice, Yang Jie immediately knew that he was Zong Quan.

"Miss Mina Fujita, I didn't expect to meet you here, it's such an honor. Yang Jie ignored Zong Quan and looked at Miss Mina Fujita in Japanese.

"Mr. Yang, I didn't expect you to speak Japanese so well. Mina Fujita looked at Yang Jie suspiciously.

"At that time, if there was a translator, I didn't have to be ugly. Yang Jie said.

"Hey, you're a friend of Miss Mina?!" Soizumi looked at Mina Fujita suspiciously.

"yes, come in and have a few drinks?" said Mina Fujita.

"Then bother. Yang Jie said with a smile.

"Secretary Xu, are you coming here with Mr. Yang for dinner?" asked Mina Fujita with a smile on her face.

"We were eating next door just now, and we heard the conversation between Sozumi-kun and them, and we knew that Miss Mina was coming, so we came over to say hello. Xu Youlun was secretly surprised, he had never seen this Fujita Mina before, but she recognized herself at a glance, presumably she had studied herself a lot.
