Bridger Cobain really wanted to tell him loudly, what's wrong with dividing your pork now? If you can, just disagree. Let's see who regrets it in the end.

After all, my arms couldn't twist my thighs.

In the end, Martin signed his name after checking the agreement. After all, it was just a framework agreement that did not require lawyer identification. After he signed his name, he handed it to the other two people.

"It's been a pleasure working together," Bridger Cobain grinned.

Max originally wanted to find Bridger Cobain to invest in SpaceX, but after seeing this situation, he hesitated a little, wondering whether SpaceX would be divided like Tesla.

This was something he couldn't tolerate.

The reason why Max can tolerate Tesla is because he has no choice but to control Tesla.

Spacex is really under his control, and he is not willing to do such a thing. Spacex must maximize its profits if it wants to raise funds.

"It's a pleasure to work together." Martin Eberhard shook hands with Bridger Cobain in a very depressed mood.

In addition, Max and Mark also shook hands with Bridger.

"Martin, you have to make plans quickly regarding Tesla's KPI. This matter cannot take more than a month at the latest, otherwise the framework agreement will lose its legal effect." Bridger Cobain looked at Martin and said.

"I will draw up a KPI plan as soon as possible." Martin Eberhard replied.

"I won't stay for long if my company still has things to do. Mr. Max, if Spacex needs financing, you can call me and contact me." Bridger Cobain said, turning to Max and said.

"No problem, I will contact you if necessary." Max Elon took the business card and said.

March 12, 2006, China time.

Changchun Institute of Optics and Mechanics.

It has been nearly a year since Jiang Shangyi came to Huaxia from Wanwan.

Although he is the director of Kirin Wafer Fab, he has never worked a day shift at the fab. Since he came to Changchun Optics and Machinery Institute, he has not left in the past year.

During this long period of time, Jiang Shangyi's two young apprentices found true love at the Changchun Institute of Optics and Mechanics.

Jiang Shangyi's daily job is to study and develop independent photolithography machines with Chen Xuezu.

As for the improvement of the lithography machine, the two have handed it over to their respective apprentices to cooperate and improve it.

Today is the day for the transformation and acceptance of the 45nm lithography machine.

Jiang Shangyi, Chen Xuezu and the older generation of researchers from the institute came to the lithography machine modification room to inspect their research results.

Zhong Feixiong, Su Xinhong and Tan Shaofeng walked up to them and called: "Teacher."

"Yes." Jiang Shangyi and Chen Xuezu nodded and replied.

"The 45-nanometer lithography machine transformation project has been completed. We replaced the original control system with the Kirin control system and added some sensors to the original system. The system recognition rate and calibration speed increased by 35% on the original basis.

In addition, we also adjusted the deep ultraviolet light, increasing the exposure speed by 27% compared with the original, and increasing the production capacity of the lithography machine by nearly 30%.

After transformation, the daily output can reach 320,000 pieces." Zhong Feixiong introduced.

The original control system used the Vxworks system. The Vxworks operating system is an embedded real-time operating system designed and developed by WindRiver Company in Lighthouse Country in 1983. It is a key component of the embedded development environment.

With good sustainable development capabilities, high-performance kernel and user-friendly development environment, it occupies a place in the field of embedded real-time operating systems.

With its good reliability and excellent real-time performance, it is widely used in communications, military, aviation, aerospace and other high-tech and real-time demanding fields, such as satellite communications, military exercises, ballistic guidance, aircraft

Navigation etc.

Most of the industrial equipment systems abroad use the Vxworks system.

In order to completely localize the lithography machine, Jiang Shangyi and Chen Xuezu proposed to use a self-developed system. Finally, Kirin Software dispatched a team to the Institute of Optics and Mechanics to independently develop an operating system in four months.

The reason why it can be developed so quickly is because this system is based on the Pangu system.

The powerful system coupled with the powerful CPU has greatly improved the operating efficiency of the lithography machine. In addition, they have also improved the light source, and the improved light source has greatly increased the exposure speed.

The new light source was developed by a research and development team led by Jiang Shangyi and Chen Xuezu.

Of course, in addition to studying deep ultraviolet light sources, they also conduct research on ultraviolet auroral sources. Now they have developed some clues and will be able to develop an ultraviolet auroral source in less than two years.

In order to study the ultraviolet auroral source, Chen Xuezu submitted dozens of reports to his superiors, which allowed the Institute of Optics and Mechanics to mobilize top researchers from all over the country. Otherwise, the ultraviolet auroral source project would not be able to progress at all.

Of course, in addition to the assistance from above, there is also Cao Mang's support. If it were not for Cao Mang's funds to support it, there would be no way for this project to proceed.

The most important thing is that when he applied, his superiors were not optimistic about the research and development of photolithography machines at all.

However, this year, the attitude towards the research and development of lithography machines has changed a lot. All this has benefited from the research results of the Institute of Optics and Mechanics and Deep Blue. These research results have also given the authorities hope.

"Not bad, let's do a trial run." Chen Xuezu nodded with satisfaction.

Su Xinhong and Tan Shaofeng made a final inspection of the lithography machine. Then they put the silicon wafer and light into the lithography machine. Zhong Feixiong pressed the run button of the lithography machine after receiving their signals.

Because the inside of the lithography machine is closed, there is no way to check the internal conditions of the lithography machine. We can only check the running speed through the system. After 27 seconds, a silicon wafer is exposed.

This speed is eight seconds faster than the original speed.

In fact, this speed is not very fast. In future generations, it would only take twelve seconds. If you want to increase the speed of the lithography machine, you cannot do it just by relying on the system and calibration. It must be equipped with a more advanced motor.

Only more advanced motors can speed up lithography machines.

After testing a hundred wafers in a row without any problems, Jiang Shangyi and Chen Xuezu left.

If you want to thoroughly verify whether the modification of the photolithography machine is successful, you must complete the subsequent etching and cleaning. Only after the yield rate is obtained will you know whether the modification is successful.

The yield must reach over 99.95% to be considered successful.

In fact, a yield rate of more than 50% is considered successful, but this yield rate will significantly increase the cost. Such a yield rate will increase the cost of the chip by at least 1.5 times.

Such a low yield is destined to be impossible for large-scale commercial use.

That’s why it is said that the yield rate must reach 99.95% or above to be considered successful.

However, it is not difficult for them to have a yield rate of more than 99%. The yield rate of a previous transformation has reached 85%.

Zhong Feixiong is very confident in this transformation.
