Lithography machine is one of the core equipment in the field of semiconductor manufacturing, and its technical sophistication and performance directly determine the accuracy and efficiency of chip manufacturing. With the rapid advancement of global information technology, lithography machines are increasingly widely used in integrated circuits, microelectronics, optics and other fields, and at the same time, they have also ushered in unprecedented development opportunities.
A lithography machine is a high-precision manufacturing device that utilizes the principle of optics and is tasked with precisely transferring a pre-designed circuit pattern from a reticle to a silicon wafer. It works by directing a specific wavelength of light through the circuit pattern on the reticle and projecting onto a silicon wafer coated with photoresist. Subsequently, under the influence of a series of chemical reactions, the circuit pattern is precisely copied onto the silicon wafer. Lithography machines play a vital role in the semiconductor manufacturing process, and their technical level is directly related to the accuracy and performance of chip manufacturing.
For this reason, I have repeatedly reviewed and studiedI will "lithography machine".The concept has been carefully sorted out, and several high-quality leading enterprises have been selected, especially the last one, which has a very high chance of certainty, and it is recommended to collect it.
Tongfei shares

The company cooperates with the University of Science and Technology of China to research photoresists such as photosensitive polyimide (PSPI).
Finally, I also selected a leading company, or will be the first leader, is expected to double the main rising wave, optimistic logic is as follows:
As a member of the "Diversified Computing Industry and Standards Promotion Committee", the company's middleware products are applied to the current mainstream computing servers, and have completed compatibility and adaptation with ecological partners such as Haiguang, Kunpeng, and Ascend.
The stock price adjustment is sufficient, the bottom of the stage is multiplied, and the chips are highly concentrated.
From a technical point of view, the daily limit copy + long arrangement, MACD daily and weekly monthly three-line golden cross, the main high control, is expected to double the main rising wave.
