Chapter 779: Spring Festival gifts, attacking a group of manufacturers

When Chinese netizens and various friends and businessmen were attracted by the various new factory construction plans of the Nanshan Group, Nanshan Chemical ushered in an important breakthrough.

"Mr. Cao, our EUV photoresist has been successfully developed and will enter mass production as soon as next month."

Lai Yuanhong came to Cao Yang's office in a very good mood and personally reported the important breakthrough of Nanshan Chemical.

The Spring Festival is coming soon, and Nanshan Semiconductor is still worried about whether there will be photoresist for their use after the New Year.

Now that Nanshan Chemical has successfully completed the EUV photoresist, coupled with other types of photoresists that have made breakthroughs in the past, it can be said that the photoresist problem that plagued Nanshan Semiconductor has been completely solved.

The next step is not only to meet its own photoresist needs, but also to consider promoting it to all semiconductor companies in China for use.

The good days of photoresist companies in the United States and Japan will be completely gone forever.

"Has the performance of our own photoresist been compared with similar products from JSR and other companies?"

Although Cao Yang is very confident in the performance of the EUV photoresist he personally participated in the research, the specific testing work is still led by Lai Yuanhong and others.

Where can you find so much funds for industrialization?

As for the exposure tolerance, it is not easy for Nanshan Chemical to achieve a level similar to that of JSR.

Whether you are good or bad is sometimes not so intuitive.

"At that time, we can form a full range of photoresist production for chip production, so that imported photoresists will slowly withdraw from the Chinese market."

"The next step can even be to further develop photoresists for LCD displays and other types of photoresists, so that the production capacity of our production lines can be fully utilized."

"So, after our EUV photoresist is produced, it can immediately begin to replace similar products from JSR and other manufacturers?"

And no matter whether you are good or bad, it is often difficult for people to believe that you are doing better than traditional giants.

The contrast directly affects the resolving power of the glue.

The level of the etching resistance ratio also determines how thick the glue layer is required to etch the substrate to a certain depth.

In case some problems arise during the use of Nanshan Semiconductor, the losses will be huge.

Sensitivity is a measure of exposure speed.

The higher the sensitivity of the photoresist, the smaller the exposure dose required.

Even though the exposure dose used during photolithography deviates from the optimal exposure dose, a good pattern can still be obtained, indicating that this photoresist has a large exposure latitude.

After all, chemical materials are different from machinery.

What is the significance of this indicator?

So this indicator is good and it is very meaningful for Nanshan Semiconductor.

"The etching resistance ratio is basically at the same level as theirs, and the exposure latitude is basically the same, but there is still room for improvement."

So I definitely still need to ask clearly.

Although the sensitivity of the EUV photoresist produced by Nanshan Chemical is slightly lower than that of JSR, it does not affect its use. It just consumes a little more photoresist.

However, in the actual production process, there will inevitably be dose deviations due to the influence of the external environment.

"Our sensitivity is slightly lower than JSR's, but the contrast is higher than theirs."

Lai Yuanhong introduced the main performance indicators at once.

For example, if the etching resistance ratio of a certain photoresist to silicon is 10, this means that when the etching speed of silicon is 1mm/min, the etching speed of the photoresist is only 100nm/min.

Otherwise, if your photoresist has very high process requirements, the yield rate will be low and the production cost will be high.

This issue is what Cao Yang is most concerned about.

For example, some photoresists were actually produced in laboratories by universities or research institutes before.

When the results are good, focus on the process.

Many companies are afraid to invest before they are sure that their photoresist can be sold on a large scale.

As for the etching resistance ratio, this performance is usually expressed as the ratio of the etching speed of the glue to the speed of etching the substrate material, also known as the selectivity ratio.

It would be good if the funds applied for every year can be used to write a thesis.

"Yes, other indicators, whether it is thermal fluidity, expansion performance, viscosity and shelf life, are no worse than others."

For many products, China does not have any production capacity at all, but if there are not enough orders or the market is small, then it will not be economical.

Otherwise, there will be no good results and everything will be meaningless.

Under normal circumstances, photoresist has an optimal exposure dose. During photolithography, the exposure dose on the entire wafer package surface should be consistent and as close as possible to the optimal exposure dose.

The steeper the photoresist transition from the exposed area to the unexposed area, the better the contrast and the steeper the sidewalls forming the pattern, the better the resolution.

And these devices don't come cheap.

However, the defective rate is relatively high, and large-scale production requires investment in specialized equipment.

Glue with a large exposure latitude is less affected by fluctuations or uneven exposure energy and is more suitable for production needs.

Nanshan Chemical's performance in this area is obviously very good.

Not to mention that these universities or research institutes are already short of money.

After all, as a boss, you must value results.

"Now that we have fixed the photoresist, let's boldly go into production."

"Nanshan Semiconductor is still building new chip factories, and some other semiconductor companies also have demand for photoresist."

"By then, both high-end EUV photoresists and relatively low-end products can be produced."

"After all, 90% of photoresist is now imported from Japan and the United States. Even for low-end products, the profit margin is relatively high."

In the past, when producing various products, Cao Yang often chose to produce high-end products and left low-end products to other companies.

After all, you can’t just go it alone in any industry, as that often doesn’t end well.

But this time the situation with photoresist is different.

Although there are some companies in China that produce photoresists, most of the photoresists they produce are used in other industries, and very few are used in the chip processing field.

So even relatively low-end photoresists are produced by a few companies in Japan.

And low-end is also relative. High-end photoresist costs 1 yuan per liter, but low-end ones cost several hundred to thousands of yuan per liter.

These things are essentially chemical materials. After large-scale industrial production, the actual cost may be less than one hundred yuan per liter.

This is based on the fact that they provide employees with extremely high welfare benefits and a variety of high-end environmental protection equipment.

Otherwise, it can be even lower.
