The Return of the Black Technology of Immortal World

Soon, the fifteenth day of the first lunar month will be over. According to the custom in Northeast China, the year will not be over until the fifteenth day.

However, this is generally only the rules of small cities. For those big cities, after going to work, they start a fast-paced life, and the taste of festivals naturally fades a lot.

No matter how comfortable Yang Qing was at home, it was time to go back to Jinshi. Not only Zhao Yuxi was urging her there, but even Weihua was going to try to stream the film.

Yang Qing has seen Weihua's tape-out plan, which is basically based on the public version design provided by Yang Qing, without much modification, and it is not the mobile phone processor chip they urgently need.

This is also what Yang Qing expected. Although the 28nm manufacturing process reduces the difficulty of the design a lot, the overly complicated real 3D transistor design and the strange arrangement of the fins are very difficult to understand. The place.

Preliminary estimates, using the architecture information provided by Yang Qing and brand-new design software, it will take at least a year to thoroughly understand the entire architecture and be able to design the entire chip as you like.

This is also based on the fact that the design software EDA is advanced enough to answer questions online at any time.

Otherwise, this time will have to be pushed back for an unknown amount of time.

It seems that it has been a long time, but everyone will know the performance of the ARM7 authorized by Weihua after the public version design.

HiSilicon has been established for more than ten years, and it has existed as a backup for a long time. It was already 2009 when they developed the Kirin series of smartphone chips and went on the market.

It has been almost ten years since the birth of the Kirin series chips, and then to the Qualcomm and four-star Kirin 9000 series that really caught up with the mainstream.

It can be seen from this that chip research and development is difficult, and it takes one year to master a brand new architecture. This is not slow, but fast enough, which can almost make people proud.

In fact, if it weren't for Yang Qing's existence, they would indeed be proud.

They were almost sure that Yang Qing was the one who figured out the chip architecture and designed a product that surpassed the performance of mainstream chips.

Such a gap has already made many people in the industry unable to afford the confidence to catch up.

Following the 200,000 chips last time, Weihua ordered another 5 million chips. At this time, the entire production workshop is working hard.

In order to meet Weihua's orders,

Yang Qing also needs to order several lithography machines from the outside world. Naturally, it cannot be EUV. Such a top-level lithography machine using extreme ultraviolet laser light source, but the 193nm deep ultraviolet lithography machine DUV produced by Nikon in Japan is also a good one. choose.

When purchasing lithography machines, Yang Qing naturally chose Weihua's channel.

Even though Yang Qing is already well-known in China, his identity is still not equal to that of Nikon, and he has no direct contact channels. An order can be delayed for several months before it can be placed, let alone delivery. .

Although the domestic 28nm lithography machine has been offline, its production capacity is obviously insufficient, at least it is not Yang Qing's turn to purchase.

Nikon was also the leader in the world's lithography industry, but at the beginning of the century, he made a series of operational mistakes and finally fell to the mediocre new opponent, a series of new technologies such as immersion lithography brought by ASML. technically.

One step behind in technology means falling behind step by step. As the number of lithography machine users decreases, Nikon's investment in future research and development is also decreasing.

Not to mention that ASML continues to attract major chip design foundries, and takes advantage of the opportunity of the United States to suppress the Japanese semiconductor industry, and almost gathers industries that are closely related to lithography machines from all over the world.

With the help of these companies, he finally broke through the limit of 193 nanometers and took the lead in realizing the extreme ultraviolet light source, that is, ultraviolet light with a wavelength of 13.5 nanometers, thus laying his leading foundation in one fell swoop.

However, Nikon's F2 light source failed. Since then, Nikon can only hover in the low-end market, but seriously, the quality of Nikon lithography machines is still good.

It’s just that Weihua, as the target of US sanctions, has many difficulties even if it buys DUVs. However, with domestic support, Weihua has successfully ordered five lithography machines after changing a vest.

The main reason is that there is no shortage of DUV in China at present, and many manufacturers such as SMIC and Ziguang have the existence of DUV.

It’s just that using DUV to achieve a 7-nanometer process requires multiple exposures. Compared with EUV with one exposure, both cost and processing efficiency are far from comparable. The chip products produced are simply not How competitive.

This is also the reason why the United States does not restrict the purchase of DUVs. The more you produce, the more you lose. In the end, you have to let go of financing, and capital has the possibility of making money.

Nikon has been in a recession for the past few years, and has been on the verge of loss all year round. The orders of Jinzhu Toothpaste Factory have also been slowly decreasing in the past two years, so for him, survival is the key, and this order is exactly what he needs urgently Life-saving medicine, it is estimated that the first lithography machine will be shipped by the end of this month, and all the lithography machines will be installed in place in two months.

Fortunately, the dust-free workshop built by Yang Qing is large enough, not to mention only six lithography machines, even if there are more than ten lithography machines, it can be easily installed.

However, even if the first lithography machine has been modified, due to the poor foundation, mainly because the power of the light source is insufficient, the processing efficiency has not been improved.

After remodeling those lithography machines this time, Yang Qing is still planning to retire the first lithography machine, so as to return to its real position and exist as a pilot test line.

With so many things urging, Yang Qing no longer has the intention to stay at home. I didn't see my mother's attitude has changed a lot because she stayed at home for too long. Those old neighbors are also behind her. He began to wonder if Yang Qing's company had gone bankrupt.

Speaking of going home this time, I stayed for a total of 37 days. Except for the vacation time in autumn, this is the longest time. Coincidentally, the two vacations are still within one year.

Since going to college, except for the winter and summer vacations during school, he has never stayed at home for such a long time.

But all this is coming to an end, Xiao Ai has already ordered the high-speed train from Shencheng to Jinshi on the 18th day of the first month, that is, February 18th.

Although it was Spring Festival travel time, especially going to the south, it can be said that it was hard to find a ticket, but thanks to Xiao Ai's super control over the Internet, she still grabbed a business seat ticket for Yang Qing.

Although it took less than a day to get back from Shencheng to Jinshi, it would be even faster if you took a plane.

However, this parting, which is only a one-day drive away, still makes people feel a lot of parting.

Before leaving, Yang Qing also replenished the aura in the pendant for her little apprentice and daughter-in-law. Under her unconscious absorption, the aura in it can be used by her for a year.

Among them, Yang Qing also hinted to her and her parents that this pendant should not be taken off at any time, and they would definitely be obedient.
