If photolithography technology is regarded as the second most difficult problem in modern integrated circuit devices, then absolutely no other technology dares to claim the first place.
The function of photolithography is to project the shape of the photoresist onto a photoresist with a precision of only a dozen nanometers or even higher, thereby "copying" the circuit structure to the silicon wafer. Of course, Ye Hua has decided to use tin wafers instead of silicon wafers.
piece.
Chip technology is commonly known as flat printing technology, which is easy to understand and is the same as printing. This is why chips are mass-produced, and the larger the quantity, the cheaper it is.
Since interference and diffraction have a great impact on pattern projection, the requirements for light sources and lenses are extremely high. It can be said that the photolithography machine is the most critical and difficult equipment in the semiconductor chip production process.
The unit price of a high-end lithography machine is already as high as 100 million euros, and you still have to queue up to buy it. China even queues up to spend money and it is not sold.
This is due to the restrictions of the "Wassenaar Agreement" led by the US imperialists. High-end lithography machines are basically not exported to the Chinese people. They can only buy mid-to-low-end ASML products. No matter how high the price is, you can't buy the most advanced ones.
For example: Intel, Samsung, and TSMC were able to purchase ASML 10-nanometer lithography machines in 2015, while China could only purchase ASML 32-nanometer lithography machines in 2015.
For the semiconductor industry, five years is enough time for the market to be updated more than three times, coupled with Intel's toothpaste-squeezing style.
Until now, China can only buy 12-nanometer lithography machines. In fact, the most advanced lithography machines have reached the 5-nanometer level, which is still three or even four generations behind.
ASML was originally going to deliver a 7-nanometer EUV lithography machine in 2018, but an "unexpected" fire disrupted it, and then it was delayed for more than two years. This year was originally
It's about to be delivered, and now something like this has happened again. This thing is probably going to cool down. There is no need to have too many illusions about the 7-nanometer lithography machine.
In contrast, among the lithography machines that have been mass-produced by Shangdu Microelectronics Equipment (Smee), the best domestic lithography machine manufacturer, the best-performing process can only reach 90 nanometers, which is equivalent to the Pentium launched in 2004.
The level of four CPUs, while in foreign countries, due to the emergence of PHC, Intel has already produced 5-nanometer chips.
The difference is not a small one.
Because of this, the high-end lithography machines needed by domestic wafer factories are completely dependent on imports. They also have to look at the faces of foreigners. If they are in a good mood, they will be given. If they are in a bad mood, they will be delayed. If they are in an extremely bad mood, they will not be given. They are fragile.
The boat of friendship will capsize for you.
This time, Shangdu Microelectronics also joined the Semiconductor Industry Alliance and became a member of the CSAC system. If the level of ASML lithography machines is the king level, then Smee is at the silver level, and at most the gold level cannot be higher.
In fact, in Ye Hua's team, except for a few such as Huawei and HiSilicon, there are dozens of others... to be honest, they are basically paddling bastards, just waiting for the master to take them down and take off.
The team is difficult to lead, and there is no better way for Ye Hua. Otherwise, what else can he do?
You can only pick up the tall ones among the short ones. These gold and silver ones are relatively the best. If you don't, there will be no better ones. And the group behind them are made of bronze and scrap iron, which is even more hopeless. Even if they can call 666, they are too lazy to do so.
Okay, that's all.
Alas, it is difficult to lead a team.
It can be said that in Ye Hua's team, he is the only king, plus three masters, two of whom are navy masters, and the rest are a group of gold and silver ranks.
Then we have to lead such a team and a team composed entirely of kings to PK...
No wonder the outside world is not optimistic about it.
However, for the optimistic Ye Hua, it is not all bad things. There are still good things. His teammates are too good. At least he knows that he is good and will listen to the master's words.
…
There is a villa area next to Zifeng Research and Innovation Center. During this period, Ye Hua visited Zifeng's R&D Center quite frequently. Naturally, he also arranged a temporary residence here, but his stay did not last too long.
It's night, Ye Hua will stay at Zifeng tonight.
In the living room, Kitagawa Ayako made a cup of hot tea and put it on the table next to him. Then she sat next to him and watched with a curious look as he operated the floating screen in front of her. She knew a little about technology but still couldn't.
She was not at a professional level. After all, her expertise was not in technology development, but she could see that the holographic display in front of Ye Hua was a mathematical model.
"What is this?" Kitagawa Ayako said casually, holding her chin.
"Logical architecture." Ye Hua said, thinking for a moment, and then turned to look at her and smiled: "The chip design we are working on has reduced size and reduced power consumption by 98%... Just imagine, adding a PHC server-level chip
Will the performance be atrocious when used on a watch or mobile phone? The integrated super CPU chip will defeat Intel."
However, when Ye Hua said this, she didn't care at all. She immediately changed the subject and said delicately: "It's getting late, go to bed."
She was wearing a silk nightgown, which was sexy, charming and still sultry.
There was an undisguised charm here, which successfully aroused Ye Hua's appetite.
But at this moment, the phone rang. Ye Hua opened it and was quite surprised. It was Bob Swan, the head of Intel Corporation. Before answering the phone, Ye Hua, who had a plan in mind, called
The holographic display operated briefly for a moment, then turned to look at Kitagawa Ayako: "First answer the phone, and then have a midnight snack."
"I hate it~ I'm not your late-night snack." Kitagawa Ayako said strangely.
However, Ye Hua had already stood up and left the living room and ran to the balcony to answer the phone. Suddenly, she took a sneak peek and immediately took out a small special USB disk from the heel of her high-heeled shoes after confirming it.
Connect to the phc port, quickly and skillfully bring up a few floating panels, and then start downloading data.
As time goes by, the speed of 5g network is not as fast as usual.
She also secretly glanced at the balcony from time to time, glancing over it every second or two out of the corner of her eyes. Ye Hua's unclear conversation came from the balcony, as if he was having a heated argument with the other end of the phone.
"Hurry up, hurry up..." Kitagawa Ayako felt very guilty now. She finally waited for an opportunity. She bit her lower lip with her white teeth and murmured in her heart. At this moment, she could feel her heart pounding.
She understands legal affairs and Chinese laws, and knows that if this matter is exposed, she may face a prison sentence of more than 20 years and a fine of more than 100 million U.S. dollars, neither of which she can afford.
On the balcony, Ye Hua said to the communicator: "...Mr. Swan, you want me to disband the CSAC system? I'm sorry, I can't comply. Everything else can be discussed. There is no room for negotiation on this issue. I have to give my
The partners give an explanation...you said they will withdraw automatically due to force majeure? There is nothing to say, that is their business."
The other end of the phone: "Unfortunately, we have to respond accordingly... Listen, Mr. Ye, there is really no need for us to be so tense. You have really overreacted on this matter recently. News will be released soon."
If things calm down, things will be settled, and finally..."
Before Bob finished speaking, Ye Hua hung up the phone and walked to the living room. His eyes fell on Kitagawa Ayako, and he returned to his original position and sat down. Next to him, Kitagawa Ayako was as calm as ever.
Ye Hua immediately slapped her buttocks: "Go and warm the bed, I want something hot."
"I obey~~" Kitagawa Ayako gave her a charming and seductive look in a coquettish manner, but she also stood up and walked to the bedroom obediently.
Watching her leave the living room, Ye Hua withdrew his gaze and immediately brought up a display panel and entered the hidden background. A series of information came into his eyes. The data record showed that the "tsi" file was downloaded one minute ago.
Ye Hua couldn't help but raise the corner of his mouth and sighed secretly: "This sexy beauty is really not polite to me, a whole 47.5 grams of information."
She really knows how to seize opportunities. As long as she is given an opportunity, she will definitely take advantage of it and she is very courageous.
After disconnecting from the private server in the cloud and turning off the holographic display, Ye Hua stood up and walked to the bedroom. It was unbearable for her to steal so many things and she had to be punished severely.
Xiaohua, who hadn't eaten for several weeks, turned into Fang Hua for tonight's late-night snack...
