Yang Jie was also surprised when he learned that the extreme ultraviolet lithography machine developed by Huang Mingchao and others was very sensitive to light sources with a wavelength of 12 nanometers.

In the previous life, the wavelength of the extreme ultraviolet lithography machine developed by Acemoore was controlled at 13.5 nanometers, which was mainly because of the photoresist, which was mainly because the formula of the photoresist was mainly in the hands of a few companies such as Sumitomo, toK, and Dow, and the formula was naturally decided by them.

Huang Mingchao's formula is different, and naturally has different photochemical effects on different wavelengths of extreme ultraviolet light sources.

In the past, Huang Mingchao and his experiments were mainly to use a scanning tunneling microscope to observe the reaction of photoresist to the dose of light source, and they could not observe this reaction process in real time, so Huang Mingchao and they could only adjust the formula by trial and error.

Now with this divine light source facility, a series of snapshots can be taken by using the pulse nature of the light source's beams, and these snapshots are aggregated to form a dynamic image of the sample changes over time.

With this set of technical equipment, you can clearly observe the various reactions of photoresist when illuminated by the light source, which can allow Huang Mingchao to analyze and judge the specific performance of photoresist faster, so as to have a very clear goal for the adjustment direction of the formula, which can greatly shorten the research and development time.

Now because a large part of the major domestic wafer factories use Huaxing Semiconductor Materials Company's photoresist products, the photoresist business alone also brings huge profits to semiconductor materials companies every year, so it is enough to support the company's research and development in this area.

Photoresist is only a sub-business of the semiconductor materials company, which also develops high-purity targets, thin film materials for thin film transistors, gallium nitride materials, crystalline silicon materials, etc., with a total of thousands of engineers.

Although the annual R&D investment of the semiconductor materials company alone is more than one billion US dollars, the annual revenue of this subsidiary is also more than 10 billion US dollars, although the scale is not large, but it is really very profitable, and the profit margin is extremely high.

Due to the high technical threshold of semiconductor materials such as photoresist, the world can supply those large material companies, the number is very small, Yang Jie is relying on the industrial chain established by himself to use the materials provided by his own company in a short period of time to make semiconductor material companies from scratch, from weak to strong, without reducing product quality on the premise of carefully cultivating semiconductor material companies, and now it has also become a company that can wrestle with overseas large material manufacturers.

Now many overseas customers have also begun to choose Huaxing semiconductor materials company's products for production, and the number of overseas customers is also increasing.

At the same time, because the materials of overseas companies are replaced by their own materials, the production cost of their own products is greatly reduced, and the products of the whole company are always maintained with sufficient profit margins.

In the previous life, although the domestic semiconductor industry was also very prosperous, they were separated from each other, and many semiconductor materials were in the hands of overseas companies, which determined the pricing power.

But now the autonomy of the three major companies of Zhongjing Micro, Huayue Electronics Co., Ltd., and Huajing Technology Group Co., Ltd. is very high, and at the beginning, it mainly uses overseas semiconductor materials, and then gradually begins to replace it with materials from semiconductor material companies, which are very synchronous in this regard.

Therefore, in addition to Huaxing Semiconductor Materials Company, there are more than 10 companies in China that can provide reliable localized semiconductor materials, and the localization of semiconductor materials has reached more than 70 percent.

However, in the subdivision of lithography mask mask, it is because of the high concentration of the market and the serious oligopoly, Fengchuang Group, Neon State's DPn and social toppan occupy more than 80% of the market share, but the market size is not large, at this stage it is only more than two billion US dollars, so semiconductor material companies have no force in this regard, but mainly follow several companies are cooperative.

Yang Jie has never said that he wants to swallow the entire semiconductor materials market, these companies have been developing in these segments for so many years, and naturally they have their advantages.

Moreover, Huaxing Group has now mastered the core technology of the semiconductor industry, and naturally has the confidence to cooperate.

Moreover, these companies are also very happy to cooperate with Huaxing Group to develop various high-end lithography mask masks for Huaxing Group.

Now China has become the world's largest chip production base, these mask factories naturally attach great importance to the domestic semiconductor market in the rabbit country, Fengchuang Group has also built the highest level of mask factory in Tanzhou City, specializing in providing high-end masks for Zhongjing Micro, Huayue Electronics Company, Huajing Group Company, Tianma Technology Company and other companies.

Huaxing Group is now developing an extreme ultraviolet lithography machine, and naturally has been in contact with Fengchuang Group Company, hoping that they can develop a photomask for extreme ultraviolet lithography mask.

Extreme ultraviolet lithography machine lithography uses specular reflection light instead of refracting light with a lens, so the photomask used also needs to be changed to reflective type, and the silicon and molybdenum layers covered on the substrate are used instead.

One of the biggest solutions is the use of multi-beam devices, which require companies that manufacture electron beam devices to develop multi-beam products.

It is also because the extreme ultraviolet light source is too destructive, even if Fengchuang Group can provide photolithography mask, but Huaxing Group must also develop a protective film of photomask, providing a physical barrier to block external pollution, which can prevent fine dust or volatile gases from polluting the surface of the photomask, and reduce the cleaning and inspection of the photomask when it is used.

Moreover, if the transmittance of these films to the light source is too poor, it will greatly affect the output of the lithography machine, and if the wafer throughput of the lithography machine per hour is too low, Yang Jie can not tolerate it.

In order to achieve these design goals, Huaxing Group still has a lot of research and development to do, and these technologies cannot be matured without five or six years of effort.
