Chapter 125
The production of diamond chips was extremely difficult and torturous at the beginning!
Because the core logic circuit and architecture design of the 1-nanometer chip, even the production of the mask version, was successfully completed with the help of Dabai.
Therefore, at the beginning, Zhonghai Optoelectronics Institute was confused by this "smooth" success, thinking that making 1-nanometer chips is just that, there is no difficulty!
However, as soon as they got on the lithography machine, they were dumbfounded and very devastated!
In the 1nm chip process, the operators of each program are trained by Dabai, thinking that they have mastered the process flow very skillfully, and they are completely experts!
However, at the beginning of the actual operation, there were still frequent problems and errors, resulting in the first 50 diamond wafers, all of which were engraved!
Due to the tight time limit, there was no time to customize the large chemical vapor precipitation reactor, that is, the CVD reactor, so the specifications of these diamond wafers were 8 inches in size, which is considered a relatively small wafer.
The chip redesigned by Dabai is almost half smaller than the previous chip, so that an 8-inch diamond wafer can hold 550 chips of this size, but that's it, the first 50 diamond wafers, still failed to make a qualified chip!
The manufacturing cost of such a diamond wafer cannot be reduced to 400,000, and in this way, more than 20 million have been scrapped in their hands!
This is not counting photoresists, rare metals and other expensive main and auxiliary materials!
Chief Engineer Zhang Xingshi called Qiao Changsheng with a crying voice to report this matter, who knew that Qiao Changsheng didn't care at all, and said that he would continue to build, and when Meng was also right, the diamond wafer tube was enough!
Then, a little impatiently said, if it didn't work, don't call him, and then hang up the phone!
Qiao Changsheng's attitude of not caring surprised General Engineer Zhang, and at the same time, it was also a kind of disguised comfort for him!
"Such a huge loss did not make Director Qiao feel the slightest anger and dissatisfaction, but instead blamed him for making a fuss!"
"No wonder people are called little devils, gee, look at people's temperament, this pattern!"
Then, Chief Engineer Zhang didn't care anymore!
It doesn't matter to Party A, what is he afraid of?
As a result, the feeling of trembling and panic disappeared in a blink of an eye!
Chief Engineer Zhang rolled up his sleeves, urged the technical personnel to come, continued to feed inside, and then the loser continued to engage!
Regardless of the cost, finally, when the 78th diamond wafer was etched, a qualified 1 nanometer diamond chip was successfully manufactured!
After testing, on this wafer, three qualified diamond chips were detected!
When the crowd watching outside the clean workshop heard the good news, they all hugged together excitedly, and some couldn't help choking!
In this way, the production of 1 nanometer chips slowly began to get on the right track, first a diamond wafer on a few qualified, then increased to a dozen, hundreds of pieces, until finally, the yield can be stabilized at about 25% to 35%, which is a very good result!
Then, the mass-produced chips are quickly sent to the advanced packaging and testing plant less than 5 kilometers away from Guangke Technology for testing and packaging!
Here, these diamond chips are cut off the diamond wafer one by one, tested one by one, and graded according to performance, and the best performing chip is left for packaging last, starting from the lowest level.
Similar to the problems encountered by Guangke Technology, at the beginning, the packaging and testing was not very smooth, because the size of the chip was too small, many previous equipment, have been adjusted and partially transformed, and the fixture and laser spot welding equipment, have been considerably optimized, these work, are also Guangke semiconductor engineers, to help the packaging and testing plant to complete.
Later, slowly with the gradual familiarity of technicians with the 1nm chip packaging and testing process, the product qualification rate also rose rapidly, and finally it could basically stabilize at the level of about 85%.
Since Kong Bai successfully developed the nickel-63 portable nuclear power battery, in addition to the development of the super battery material production process, in addition to the optimization of the super battery material production process, more energy has been focused on the research of Dabai's new series of server architectures and basic materials of components!
For Kong Bai, the "super battery" project has ended several days in advance!
Now, the newly designed server architecture of Dabai is completely equivalent to overturning and starting over compared to before!
First of all, the chip packaging technology has been completely designed and optimized.
A packaged processor is equipped with 256 diamond chips, which is what we commonly call a 256-core processor, and nearly 100 billion transistors are etched into 128 layers on each diamond chip, so that 25.6 trillion transistors are integrated on a mobile phone-sized processor packaged in this package. Compared with the current hundreds of billions of processor chips, only from the number of transistors, it has increased by 256 times, moreover, the processor size is much smaller, the chip power has also increased to the level of about 180W
Of course, this processor is tailored for Dabai's artificial intelligence, the most important of which is the improvement of integration, that is, the improvement of computing power, its function, but than the previous processor, is more single, belongs to the type of sword to the extreme.
Then there is the motherboard, which is also tailored for Dabai, the groundbreaking use of a 16-layer board design, its size is also more than half of the size of other server motherboards, it looks like a very thick piece, giving people a very solid feeling
Such a sturdy motherboard, but the function is very simple, only two bus controllers, one for reading and storage operations, the other for external device port control, capacitors and various components on the motherboard, are special, using some new carbon nanotube materials, can not only improve its electrical performance, but also partially reduce power consumption, reduce heat.
In addition, the most on this motherboard is the socket, 4 processor sockets and 16 memory sockets, the rest is the power supply, data interaction socket and optical fiber socket, completely abandoning other interfaces integrated on the previous motherboard, it looks very simple and powerful!
Fortunately, this is in Zhonghai, as long as the price is high, people are hammered with a hammer, and they can also ensure on-time delivery, not to mention only optimizing and improving the material.
Guangke Technology is not only responsible for the production and manufacturing of 1 nm diamond chips, but also produces some silicon carbide power devices and power components in the 28 to 56 nm process according to Kong Bai's requirements, and also uses the 14 nm process to manufacture some diamond-based memory and flash memory chips for further manufacturing server memory and hard disks.
Then on day 10, I finally assembled two compute servers and a data server!
Don't look at only two computing servers, but densely packed with 16 motherboards of the kind mentioned above, such a server, its theoretical data processing capacity, is already more than 5 times the processing capacity of the old shipyard data center!
And that data server, its data storage capacity, is already more than 100,000 TB of data storage capacity in the old shipyard data center!
Just such a computing server, according to Kong Bai's plan, must be at least 100, and the data server must be at least 50!
In this way, the processing power of Dabai will be at least about 500 times the computing power and data processing capacity of the three centers of the old shipyard, and will reach at least 140E FLOPS computing power!
That's a pretty scary number!
This number is far from the shadow of the world's fastest supercomputer!
Then, on the eleventh day, the dedicated optical fiber had also been erected, and Dabai began to "move"!
