Of course, copying is not Lin Xiao's character. After so many months of thinking, he has come up with a better plan, which can increase the purification speed by about 10%.

However, when it comes to the hardware issue of polishing, the "use" principle cannot be used. After all, it is certainly not a problem for local Japanese companies to buy top-notch polishing machines.

"So I have two directions now."

"First, develop a new grinding disc material, and second, develop a new polishing fluid."

Polishing accuracy is tested by material issues. At the same time, grinding disc and polishing fluid are indispensable.

For example, the thermal expansion coefficient of the grinding disc material must be accurate. If the grinding disc material expands due to friction and heat, it will obviously affect the final polishing accuracy.

The polishing fluid not only dissipates heat to the grinding disc, but also uses the small particles of polishing powder inside and the protrusions measured in nanometers on the surface of the material for polishing. After all, the final chip is engraved on a process measured in nanometers.

After a short period of thinking, Lin Xiao finally made a choice: "Grab it with both hands, and be hard with both hands."

In particular, the polishing process is not only used for polishing silicon wafers. In the future, the optical lenses of photolithography machines also need to innovate the polishing process.

In the past, under the boasts of the media, carbon-based chips seemed to have become a new area where China could achieve overtaking in the chip field. However, obviously, the threshold of polishing process alone is enough to continue to prevent China from thinking about engaging in carbon-based chips.

base chip.

Therefore, polishing technology is also an area where foreign countries impose sanctions on China.

It is imperative to achieve a breakthrough in this field.

He opened the system panel and looked at his remaining truth points.

【283.5】

A pretty high number.

Later, in the process of solving various problems with the lithography machine, he will definitely encounter some problems. If Lin Xiao really can't solve them, he will consider using truth points.

Of course there are so many truth points that must be used.

Of course, he now also wants to know how many truth points are needed to solve his problem so that he can be mentally prepared.

"The system is a combination of polishing abrasives and polishing fluid that can increase the polishing rate of silicon wafers by five times and stabilize the surface accuracy at around 1nm. At the same time, the cost cannot exceed at least twice the current price. How many truth points are needed?"

"Based on the host's civilization level and the host's comprehensive ability, 10 truth points are required."

Lin Xiao was stunned: "What? Only 10 truth points?"

Is it so cheap?

He now has nearly 300 truth points, and these 10 truth points are nothing at all!

"System, you actually look down on the polishing process so much?"

System: "This requirement does not require a breakthrough in finding the truth. It is just a matter of permutation and combination of various relevant knowledge of the host's civilization, so only 10 truth points are required."

Lin Xiao: "...Okay."

"Then you might as well just give it to me."

system;"……"

No reply.

Lin Xiao thought for a moment, and then asked: "What if it is an optical lens polishing disc material and polishing fluid with an accuracy of 50-100pm-rms?"

System: "Requires 11 truth points."

Lin Xiao's eyes gradually lit up.

Only 11 truth points?!

The requirements for the optical lens grinding disc of the lithography machine are obviously greater than the requirements for the silicon wafer grinding disc, and the result is only 11 points of truth.

"System, this is the first time I realize you are so cute!"

Although the system does not pay attention to these technologies that humans on earth already have, and has a completely "disdainful" attitude, it is great news for him.

Because this means that he will be able to help China break through sanctions imposed by almost all countries in the world at a lower cost!

Thinking of this, he couldn't help laughing.

He wants China to create their own cutting-edge chips in at least the next few years!

"It's a breakout anyway. Which direction is not a breakout? Let's start with the polishing process to complete the first breakout."

Then, he spent 10 truth points to directly exchange them for silicon wafer grinding disc materials and polishing fluid materials.
Chapter completed!
