Rebirth 1999: Opening the Age of Black Technology Chapter 583

Chen Xiao directly took the chip and put it in his palm to play with it carefully.

In Zhang Jing's view, Chen Xiao's action was reckless.

But because Chen Xiao is the boss and his immediate boss.

Therefore, even if Zhang Jing was very painful, he did not dare to complain at all.

The 65-nanometer chip is only clocked at 2.0G Hz.

Although the operating frequency is much lower than the first generation Pangu and Pangu 2 chips.

But because the process is more than double that of 130 nanometers.

Therefore, the actual operation speed has been greatly improved compared to Pangu No. 1 and Pangu No. 2.

Why is Chen Xiao not as careful as Zhang Jing?

Because before he was reborn, he also played the new 3-nanometer level at will. .

I accidentally broke the pin and then soldered it myself.

In the end the chip still works.

Compared to the previous product of rebirth.

The 65nm process chip is just an antique-level product.

Therefore, in terms of psychological feelings, Chen Xiao will not be as careful as Zhang Jing.

Chen Xiao switched his left and right hands, preparing to carefully observe the pins and other parts of the chip.

Who knew that this action shocked Zhang Jing and others.

"Be careful!" Zhang Jing felt that his heart was about to jump out, and he couldn't help shouting in a hurry.

He also thought that Chen Xiao accidentally slipped his hand, and the chip was about to fall.

It turned out that Chen Xiao was changing hands.

This is a long sigh of relief.

Look at the way Jing is so cautious.

Chen Xiao laughed and said, "Our products still have to withstand ups and downs. Don't be unable to use them because of a little bump."

Zhang Jing smiled awkwardly.

The words indeed say so.

But in practice you have to be careful.

In Chen Xiao's view, the size of the chip is still too large.

However, compared to the 130-nanometer class Pangu No. 1 and No. 2 chips, the volume is still much smaller.

The pins of the chip are densely packed, because the chip has been packaged, so Chen Xiao can't see the more precise structure inside.

The technicians began to report the specific parameters and performance of the chip to Chen Xiao, Zhang Jing and others.

"This chip is named Pangu 3 chip."

"It adopts a dual-core design, the system bus (FSB) is 800 MHz, the main frequency is 2.0Ghz, the first-level cache is 512K, the carbon crystal particles are used, and the second-level cache is 12 megabytes, and the carbon crystal is also used. particles."

"The operating voltage is about 1.25 volts, and the cooling power is 45 watts."

"The number of pins is the same as that of Pangu No. 1 and Pangu No. 2, which can be adapted to the listed Angda motherboards."

This chip was designed by Chen Xiao himself.

Therefore, even if the staff did not make any reports, Chen Xiao was familiar with the parameters of the chip.

But Chen Xiao knew.

At present, the chip design of Changtian Technology is generally based on the traditional Intel chip.

Therefore, the entire production process is relatively close to the traditional production process of Intel chips.

This is also what Chen Xiao regrets.

The more he knows about the corresponding skills of the technology tree, the more Chen Xiao knows that the current chip design and production process are relatively backward.

There are two main reasons why Chen Xiao said this.

The first is that the size of the chip is larger and follows Moore's Law.

Large-scale chips can only be applied to bulky desktops, and laptops that look relatively light but are still relatively bulky.

With the advent of the mobile Internet era.

Computers will appear in every aspect of life.

If the computer is still produced in such a bulky volume, then its scope of use is limited.

This is that the power consumption of the chip is still too high.

Whether it is a laptop tablet or a mobile phone in the future.

What is needed is a chip with high performance and low power consumption.

Only in this way can the portability of the device be increased.

High power consumption means high power consumption.

You can't ask users to hold the charging cable all the time, and find a place that can be charged all the time for office or entertainment, right?

Chen Xiao was born again.

Even later generations of smartphones and wearables have become quite common.

Chen Xiao was very dissatisfied with the computing power and batteries of these devices.

Take mobile phones for example.

As long as you go out, in addition to your mobile phone, you will definitely bring a mobile phone charger or power bank.

Even without it, the so-called shared power bank appears in every corner of the city.

Is this really convenient?

It seems convenient, but it is not.

No user does not complain about the battery life of the phone.

It's fine in the city.

If you go out on an outing, even go to the mountains.

Then a few thousand mAh of mobile phone or laptop power will make you quite painful.

So Chen Xiao firmly believes that the current chip production process is just a transition.

There must be better solutions in the future.

The reason for the rush to launch 65nm chips.

In addition to winning in the brutal struggle with Intel, and taking the lead in the coming mobile Internet era.

The most important thing is to accumulate more users and have more influence.

Upgrade the chip tech tree as soon as possible.

Feeling emotional.

Chen Xiao still encouraged the technicians of Yanjiang Semiconductor Company.

After all, the task can be completed in such a short time.

Everyone still worked hard.

Moreover, even the production process of the entire chip is done according to Western standards.

Changtian Technology still has its own bright spots.

One of the biggest highlights is the first level cache and the second level cache.

The first-level cache and the second-level cache still inherit the characteristics of the Pangu 1 and Pangu 2 chips.

Chen Xiao believes that even if Intel announced 65nm performance.

in operation speed.

Changtian Technology will definitely have an advantage.

Therefore, the Pangu No. 3 chip developed by Changtian Technology this time should be the most advanced commercial chip in the world so far.

none of them!

"Have you been tested?"

According to reason.

Before reporting to the boss, the researcher should conduct a complete performance test on the chip before making a work report.

But this time, time is too urgent.

And everyone couldn't contain the joy in their hearts.

Therefore, as soon as the chip came off the production line, it immediately reported this matter to Zhang Jing and Chen Xiao.

A new test of the chip has not yet had time.

Chen Xiao saw the embarrassed expression on the staff's face.

He didn't blame everyone.

Instead, he said kindly: "Test the performance."

There are two ways to test the performance of the chip.

One is to use professional equipment to test the computing power, power consumption, stability, etc. of the chip after powering on the chip.

This is a factory performance test.

The second test method is more straightforward. The chip is directly installed on the computer equipment to test the comprehensive use ability of the chip.

After an hour-long test.

The staff sent more than 50 pages of test reports to Chen Xiao.

Chen Xiao looked at the detailed test report and was still very satisfied.

The actual performance of the chip is almost the same as the performance designed by Chen Xiao.

The performance deviation is not higher than 5/10000.

This kind of performance deviation is also within the range allowed by the industry.

What Chen Xiao cares most about is the yield rate.

Yield rate is very important.

It directly affects the actual cost and output of the chip.

What is the yield rate?

The ratio of the number of off-line chips that meet the actual performance standards and the total number of production.

Chips are very precise semiconductor products.

If you don't test, you can't know if he can meet the standard.

There are many chips, the appearance is complete, and the entire production process is complete.

But in actual operation, the main frequency may only be 1Ghz, and even half of the designed main frequency has not been reached.

It is also possible that the chip has a data storage failure. Although the computing power of the chip is exactly the same as the design, the calculated data cannot be exchanged with the computer through the cache.

Of course there are various other issues.

In the production process, whether the technology does not meet the requirements or the material itself is flawless, it will affect the yield of the chip.

The higher the yield, the lower the cost of the production line.

On the contrary, the production cost is getting higher and higher.

In accordance with the normal requirements in the industry.

If the yield rate is below 85%, then your chip foundry should not produce chips.

After all, this kind of yield will make the chip factory very uncomfortable after the cost is spread.

The yield rate of Intel's own chip factory and TSMC is above 95% all year round.

Zhang Jing said: "At present, our yield rate can reach 92%."

92%?

This kind of yield rate is acceptable, but Chen Xiao is not very satisfied.

Zhang Jing said the reason.

"The main reason for the low yield rate is that the quality of the photoresist is not high. Many times in the lithography step, the chip drawings are not printed on the wafer due to overexposure."

Photoresist!

during the entire production process of the chip.

Almost every part and every raw material has a very high technological content.

At present, Changtian Technology can only try its best to keep all the technologies in its own hands.

But any science and technology, especially in the field of materials, relying on the guidance of Changtian Technology in just a few months, it is difficult to achieve leapfrog progress.

Photoresist, which is critical to chip production, is the most critical factor affecting yield.

"Currently, the photoresists we use are mainly from two companies."

"One is the Yanjing Chemical Plant."

"One is purchased from a related company affiliated to Toyo's Extreme Ultraviolet Lithography System Research Association."

The reason why Yanjing Chemical Plant can produce photoresist is that it was commissioned by the Semiconductor Research Institute of Xiaguo Academy of Sciences to build a photoresist research institute and production base.

In the 1960s, Yanjing Chemical Plant approved forest as raw material, and made polyvinyl alcohol cinnamate glue by thermal process.

In the early 1990s, the Institute of Semiconductors, Xia Guo Academy of Sciences, has followed the footsteps of foreign countries to study EUV photoresist technology.

Although there are some improvements, there is still a certain distance from the international advanced level.

At present, the photoresist produced by the process owned by the Yanjing Chemical Plant can indeed be used in the production of 65-nanometer chips.

The procurement cost is lower, but compared to Toyo's EUV technology, it has more defects.

The quality of the photoresist purchased from Toyo is very good, and the yield rate is also very good.

However, the purchase price is relatively expensive, and if large-scale mass production of chips is required, the number of purchases may be limited.

Therefore, Changtian Technology can only purchase the photoresist of Yanjing Chemical Factory on a large scale.

Moreover, this photoresist has been upgraded with the help of Changtian technicians.

In short.

Raw materials like photoresist.

The dilemma faced by Changtian Technology is that it can barely use it, and there is still a big gap between the technology and the West.

Chen Xiao has established corresponding natural science research institutes in Jiangzhou and Changzezhou in Suzhou and Hangzhou.

Chen Xiao felt that traditional natural basic disciplines such as physics and chemistry should also be put into the training field.

If the foundation is not strong, how can a building be built?

Only when a large number of talents in natural basic disciplines emerge, can Changtian Technology be able to overcome more technological barriers and develop more cross-era technological products.

"What about the cost?"

This is a question that Chen Xiao is more concerned about.

Cost represents the competitiveness of a product.

If the chip cost of Changtian Technology is much higher than that of Intel.

Then this product is not competitive in the market.

Consumers are not fools.

Products with similar performance are definitely the cheaper the better.

Zhang Jing got the cost information of the product yesterday.

He said: "The cost of the Pangu 3 chip is 864 yuan, not counting the R&D investment, but only the production cost."

This is RMB denominated.

It is certainly not possible to calculate R&D costs.

If the R&D cost is calculated, the cost of the lithography machine production is included in it.

Then there is no way to estimate this chip for my son.

It will definitely not be able to pay back in a short period of time.

Fortunately, 65-nanometer chips can be used for a few years.

As long as Changtian Technology's chips can occupy the market on a large scale, they can still make a return.

Even if the chip industry chain established by this opportunity cannot be repaid, it can also play other roles in the future competition of technology billions.

Calculations like this are priceless.

The production cost is as high as more than 800 yuan.

Still more expensive.

Chen Xiao predicts that Changtian Technology's chip production cost should be more expensive than Intel's.

But it runs faster, and Changtian Technology is willing to make small profits but quick turnover, so it should be able to fight Intel.

Chen Xiao nodded and said: "The relevant information of Pangu No. 3 chip will not be released to the public for the time being~www.mtlnovel.com~ First optimize the industrial chain and prepare large-scale stockings as soon as possible."

"As long as Intel officially sells 65-nanometer Core chips, we will immediately put the Pangu 3 chip on the market."

What Chen Xiao wanted was to play unexpectedly.

Beating Intel hurts.

Just imagine, Intel has spent a lot of energy and time developing and producing 65-nanometer chips, and there is really no way to gain the desired market share.

This will have a huge impact on the global semiconductor system!

And as long as the chip can be mass-produced, the cost will be further reduced.

Zhang Jing said immediately: "I'll arrange it right away."

at the same time.

In Yanjing, Lianxiang headquarters.

There is a serious dispute going on in the conference room.
