MMB Chapter 115 Superstar's First Memory Chip
Chapter 115 Superstar's First Memory Chip
But no matter why the Dutch government and Asmer are like this.
But now that the machine has arrived, let's use such a cutting-edge lithography machine.
They can basically put an end to being stuck by the beautiful country in terms of manufacturing.
However, on the specific production of what products.
Lin Xuan discussed with Zhang Rujing, Ni Guangnan and others for a long time.
I think that the general fabs basically start from the foundry and accumulate experience first.
However, the employees recruited by Chaoxing Semiconductor now,
Many of them come from SMIC, Hua Hong, and Spreadtrum.
This is the support of several factories for "Superstar" SNA
These employees have rich experience in foundry.
So as long as they are familiar with the machine, they can even produce it directly.
For this reason, Lin Xuan proposed to launch 1GDRAM memory chips directly.
This chip is a 50-nanometer production process.
The main screen is 4"840"00HZ, which is the mainstream chip in 2007.
And this chip was first launched by Samsung Electronics in 2006.
It can form a generation gap with the 256M currently on the market.
In this year's 256M memory market, the price is around 200 yuan.
The price of 512M memory market, the highest price is about 900 yuan by Samsung
Basically, the ex-factory price of a 256M memory chip is 100 yuan.
The 512M memory chip is 300 yuan.
Based on this, according to Zhang Rujing's generational difference theory about Moore's theory,
The ex-factory price of 1GDRAM memory chips is 900-1000 yuan, which is more reasonable.
In the end, several people decided that the 1GDRAM memory chip of this "Super Star" SNA was priced at 899 yuan.
For this purpose, Lin Xuan specially downloaded it.
It cost 200 million Chinese coins, technical drawings of 1G DRAM memory chip.
And Zhang Rujing and Ni Guangnan are like treasures when they obtain the technical drawings of 1G DRAM memory chips.
This is the first time that a flower grower has surpassed the world in chip production.
Not to mention Zhang Rujing and others, even Zhang Shangzhou from the government department was so excited that he almost cried.
No one knows how excited Zhang Shangzhou is, who has dedicated his life to the chip industry.
However, what is even more exciting is the Shanghai government.
The semiconductor industry has always been one of the most important industries for the Shanghai government.
Otherwise, Magic City would not have introduced chip companies such as SMIC, Huahong NEC, and Spreadtrum.
Although the "fake Hanxin" Chen Jin happened during the period.
But the emphasis on the chip industry in Shanghai has not changed at all.
However, it is helpless that no matter how much money the Shanghai government spends, the chip industry is two to three generations behind the world's most advanced manufacturing technology.
What kind of concept is this?
According to Moore's Law, iterates every 18 or 24 months.
The chip industry of flower growers is 4-6 years behind the world's mainstream chip technology manufacturers
It doesn't look like much, but if it is reflected on the chip, it will be fatal.
For example, when others produce 512M memory, SMIC can only produce 64M and 128M memory chips.
In this case, how can you gain international competitiveness.
Moreover, memory chip giants such as Samsung and Micron will use a method when facing competition.
That is, whenever the technology is about to iterate, they will significantly reduce the price of the previous generation of memory.
The result is an avalanche of low-end memory product prices.
However, large companies such as Samsung and Micron can obtain high profits from high-end memory chips to make up for losses on low-end chips.
However, technology leaders such as Samsung and Micron can do so.
But for some small memory chip manufacturers without technology, it is impossible to do so.
For example, SMIC, in the face of the loss of low-end memory chips, it can only give up the production of memory chips and survive as a foundry.
Although I extremely resent the shameless behavior of these big factories.
But if the technology is not as good as others, there is no way.
Therefore, SMIC has always been trying its best, hoping to become a blockbuster.
However, with the emergence of Superstar (SNA), the situation seems to have improved.
For the first time, Florist has surpassed major manufacturers such as Samsung, Micron, and Hynix in the field of memory chips.
The Modu government, who understands what all this represents, naturally attaches great importance to Superstar (SNA).
In the midst of his busy schedule, Deputy Mayor Zhou visited Chaoxing again after two days.
When he saw that in a short time, the entire factory building was completely filled with various advanced equipment,
All the people are wearing white dust-proof clothing and goggles to debug equipment in the clean room, busy with trial production,
He asked through the special glass:
"How soon can it be produced?"
"Memory chips are not like processor chips, the risk of taping out is relatively small, and the design of stacked memory chips given by Director Lin is very mature,
There is no need for improvement at all, so the speed of production, packaging, and testing should be very fast!"
Ni Guangnan said to Vice Mayor Zhou......
Now Ni Guangnan was appointed by Lin Xuan as the chief engineer of Superstar (SNA) Semiconductor, temporarily responsible for production and equipment debugging.
But Zhang Rujing will often come to help.
After all, both SMIC and Superstar (SNA) Semiconductor are located in the Pudong Zhangjiang area of Shanghai.
The straight-line distance is only about 1.5 kilometers, even riding a bicycle for more than ten minutes is enough.
"Stacked memory chips?" Deputy Mayor Zhou was not very clear about this concept.
So Ni Guangnan explained:
"In fact, the basic unit of memory is mainly composed of a transistor and a capacitor. The transistor is like a switch, which decides whether to charge the capacitor. Charging means 1 in the binary system of the computer, and 0 if not charging.
If the capacitor digs a trench under the transistor to store electrons, it is a trench type, and if it is stacked above the transistor, it is a stacked type.
Internationally, the competition for this route started in 1987 with 4M memory. As for which is better, no one knows, but Samsung, Hynix, Micron, etc. all use push-style servers. "
As soon as Ni Guangnan said, Deputy Mayor Zhou smiled and said:
"Then it looks like stacking is better!"
Hearing this, Lin Xuan, who was accompanying the inspection, disagreed.
In fact, according to the technical indicators of the mall system products, the stacked type is more suitable for computer memory such as PC.
The trench type is suitable for mobile phone memory chips because of its excellent heat dissipation function.
So there is no such thing as excellence.
Although Deputy Mayor Zhou is not very clear about chip technology 1.3, he still attaches great importance to Chaoxing.
After all, this project was landed in his hands.
Once Chaoxing can succeed, it will definitely be a major achievement for him.
"How soon can the first 1G memory memory chip be produced!?"
Deputy Mayor Zhou asked
"One and a half months should be able to produce samples!"
Seeing that the mayor was so anxious, Ni Guangnan said.
Lin Xuan has no opinion on this either,
The production line he purchased from the system mall includes all equipment for cutting, etching, photolithography, packaging, and testing.
Although workers need a little time to get familiar with these more advanced equipment.
However, it should be no problem to produce a sample memory chip in one and a half months.
Mayor Zhou, who was guaranteed, left happily.
