Military Industry of Great Powers: Build the Strongest Flanker.

Chapter 210 It’s too advanced. Teacher Xiao Zhao is a little panicked

The manufacturing process used in the 14-nanometer process was used in the 180-nanometer process. There was no acclimatization phenomenon as Zhao Guoqing imagined. The whole process went exceptionally smoothly.

"Mr. Zhao, you are so amazing!"

Teacher Xiao Zhao once again used his super power to conquer everyone in Institute 102. In order to maintain confidentiality, Teacher Xiao Zhao divided the entire process into seven groups. Everyone must abide by confidentiality regulations during the manufacturing process.

Just kidding, this process alone is worth 1000 billion, and that’s in U.S. dollars.

Even if the chips from Institute 102 are used for research and they know the semiconductor structure and metal gate structure, how to manufacture them will still take them at least ten or eight years to figure out.

I just wronged Professor Hu Zhengmin. In this life, a genius may become unknown...

Teacher Xiao Zhao can’t help but feel a little guilty...

……

The trial-manufactured chip is an upgraded computational fire control chip for the phased array radar designed by Jia Pengfei's team. The finished wafer is cut into chips the size of a little fingernail.

Yang Xingye, the workshop foreman of the chip processing plant, excitedly said to Zhao Guoqing: "Mr. Zhao, the size of the entire chip is 75% smaller than the chip produced by Zhongxun's -nanometer manufacturing process!"

Zhao Guoqing said: "Let's see what the test results are like?"

The chip can be tested before it is packaged. On special equipment, the metal wires on the pins are connected to the pads, and a test circuit is originally designed inside the chip. It is enough to connect the microcomputer through the bus and run a program.

"Voltage 1.5v, base frequency 50 MHz passed!"

Zhao Guoqing nodded. The basic frequency of a chip produced using an 50-nanometer manufacturing process is only MHz!

"Voltage 1.5v, base frequency 60 MHz passing..."

"...70 MHz...80 MHz..."

It feels like there is no limit, all the way to 200 MHz... I still haven't explored the bottom...

"This……"

The performance has broken many people’s perceptions!

Until 300 MHz, the heat of the chip has reached a level that affects performance.

"Mr. Zhao, if it is packaged well, it feels like it can reach a frequency of 500 MHz!"

Zhao Guoqing shook his head and said: "What's the use? The bus frequency is 50 MHz. No matter how high the frequency your processor can reach, it can only be 50 MHz!"

"..."

If you want the processor to run at a higher frequency than the bus, you need to design frequency multiplication technology so that the processor can run at a multiple of the bus frequency. This requires major adjustments to the bus structure and the input and output components on the bus. Redesign is no less than redesigning a passive phased array radar.

"Electronic technology is a complete set of technologies, even if you only have a processor!"

But the industrial pearl has been picked, and other things are much simpler.

The constraint problem of active phased array radar has been solved. The 180-nanometer manufacturing process can design a processor with million transistors and powerful computing power, which is sufficient for the use of active phased array radar.

Zhao Guoqing stayed in the workshop for a whole day wearing protective clothing. He didn't feel anything even if he was soaked. He was waiting for a very important data.

That is the yield rate, a parameter that can declare the success of the process.

After waiting for another three hours, the staff handed over a form recording the preliminary test data of 1782 finished chips.

80% of the chips can run at a frequency of 450 MHz and work normally, while 400% of the chips above 98 MHz can run at a frequency above 99.9 MHz. Of the 350 chips, only two do not work. Normal, but the chip is designed with redundant circuits, and the backup circuit can still work normally.

"Mr. Zhao, the yield rate is close to 100%. It's incredible. The yield rate of Zhongxun's 800nm ​​manufacturing process is only 97%."

Zhao Guoqing said calmly: "So, we have solved the 180nm manufacturing process?"

Yang Xingye said excitedly: "Yes, Mr. Zhao, we have solved the 180nm manufacturing process. I just calculated it. The processing of each wafer has 800 more processes than that of 21nm. The processing of each wafer The cost has increased by about 70%!" "Only 70% of the cost increase!" Zhao Guoqing was a little surprised and looked at Yang Xingye nodding continuously.

You know, even though the processing cost of each wafer has increased a lot, due to the improvement of the manufacturing process, the number of chips processed on each wafer has increased!

"Mr. Zhao, for the same chip, using the 180nm process, each wafer can produce 800 times more chips than the 6.5nm ​​process!"

Teacher Xiao Zhao narrowed his eyes slightly and mentally calculated the cost of each chip.

"So the cost per chip is only a quarter of the original cost?"

Yang Xingye nodded and said: "Mr. Zhao, yes, it is only a quarter of the original, and the performance is probably improved by more than ten times..."

Teacher Xiao Zhao suddenly felt a cold feeling behind him. If anyone knew that Institute 102 had developed this technology, would the United States send people from the CIA to eliminate him...

Damn, it's too advanced.

You must know that the first batch of 1989 processors launched by Intel in 486 used a one-micron commercial process, and the third batch of 486 processors launched this year used an -nanometer commercial process.

According to the original history, two years later in 1993, the Pentium I processor with a 350nm process was launched, five years later the Pentium II processor with a 250nm process was launched, and eight years later the Pentium III processor with a 180nm process was launched. It will be ten years before Intel solves the problem of copper connections for transistors within the chip.

The 102-nanometer chip manufacturing process of the 180nd Institute has a yield rate of 99.9%. It can already be called a mature process, and its technological advancement is at least ten years ahead of Intel.

As for the blue giant IBM, if history continues on its original track, IBM will make a big comeback on metal gates, and the 102 Institute will be at least fifteen years ahead of IBM...

It’s only 1991!

Teacher Xiao Zhao returned to the office, looked in the corridor, and told his secretary Feng Ruilin to stay at the stairs and not to let anyone in within 20 meters of the office.

Zhao Guoqing closed the door, picked up the red intercom on his desk, and dialed the internal phone number of the General Staff... After a short ringing...

"Director Liu, I am Zhao Guoqing!"

Director Liu's expression condensed. This was the first time Zhao Guoqing called him through the internal line.

This red phone is a learned one, it is called external confidentiality, but it is not confidential internally. All contents will be recorded and reported to the special department.

"National Day, if you have any questions, just tell me!"

Zhao Guoqing cleared his throat and said calmly: "Director Liu, Institute 102 has solved the 180nm chip manufacturing process and can achieve mass production!"

"What?" Director Liu stood up subconsciously and said, "Did you just talk about the 180-nanometer chip manufacturing process?"

Both CITIC and Xineng have achieved mass production of the 800nm ​​process, and the current commercial process that has achieved mass production in the world is only 800nm.

In the past few months, Lucheng Core Energy has been able to produce chips with a 500-nanometer process, but the yield rate is only about 17%, but it is still a breakthrough.

Liu Qing remembered that some people in the expert team laughed at Zhao Guoqing at that time, saying that anyone who left Institute 101 could survive. Although the yield rate was low and could not be commercialized, Core Energy could manufacture 500-nanometer chips after all.

As for Zhongxun, which is a thousand kilometers away, they have not heard any news about the improvement of Zhongxun's manufacturing process.

The slap in the face came so quickly.

500纳米之后是350纳米，再往后是250纳米，250纳米之后才是180纳米制程……

"You guys have made a breakthrough!" Director Liu Qing's tone became extremely sharp due to excitement!

Zhao Guoqing nodded and said, "Yes, Director Liu, it is of great importance and I have to report this matter to you first!"

If this news is leaked and confirmed by Lao America, Lao America will definitely go crazy. This is a critical period for economic development. If Lao America sincerely tries to cause trouble, there will always be a lot of trouble.

"There are many benefits. It can improve our country's image and even make our country a leader in semiconductor manufacturing. But Director Liu, I have to say, the disadvantages are also huge..."
