my country’s photoresist development trend is good and the market localization rate is expected to increase

Photoresist is a photosensitive material. It is a mixed liquid that is sensitive to light. It is also called photoresist. It is an etching-resistant film produced by changes in solubility due to irradiation or radiation such as ultraviolet light, electron beams, X-rays, etc. Materials are mainly composed of photoinitiators such as photosensitizers/photoacid generators, monomers, photoresist resins, solvents and other additives.

Photoresist is usually divided into three categories: PCB photoresist, display panel photoresist, and semiconductor photoresist. According to different exposure light sources and radiation sources, photoresists can also be divided into categories such as electron beam glue, X-ray glue, ion beam glue, UV positive/negative photoresist, and deep UV photoresist. Photoresist is one of the key materials for micrographic processing in microelectronics technology. It is widely used in electronics, printing, new displays, display panels, integrated circuits, circuit board printing, semiconductor discrete devices and other fields.

According to the “Photoresist Industry Market In-depth Research and Investment Prospects Forecast Analysis Report 2023-2028” released by the Industrial Research Center, In recent years, my country’s photoresist industry has been developing well. On the one hand, with the gradual implementation of my country’s wafer fab capacity expansion plan, my country’s photoresist production has increased significantly. On the other hand, photoresist resin is the main component of photoresist and the core material that affects the performance and quality of photoresist. With the continuous improvement of scientific research and technology and the continuous breakthroughs in synthetic resin production technology, my country’s photoresist resin supply The substantial improvement in capabilities and the continuous decline in production costs have promoted the development of domestic photoresist.

From the perspective of the downstream application market, the application range of photoresist is very wide. With the strong support of the Chinese government, my country’s aerospace, national defense, consumer electronics, electronic chip and other industries have developed rapidly, and the demand for photoresist market continues to rise. Against this background, my country’s photoresist market continues to expand. From 2018 to 2022, the size of my country’s photoresist market increased by 3.51 billion yuan, with a compound annual growth rate of 11.8%. Among them, my country’s photoresist market size will be 9.74 billion yuan in 2022, a year-on-year increase of 5.8%.

From the perspective of my country’s photoresist market, due to the high technical threshold of the photoresist industry, the market concentration is quite high. At present, my country’s photoresist market share is mainly occupied by large companies in developed countries such as Tokyo Yinghua, Japan’s Synthetic Rubber, Japan’s Sumitomo Chemical, Japan’s Shin-Etsu Chemical, and the United States’ Dow Chemical. The above companies account for more than 80.3% of my country’s photoresist market share. . Jingrui Electric Materials, Chinachem Technology, Rongda Photosensitive, Nanda Optoelectronics, Tongcheng New Materials, Shanghai Xinyang, etc. are the main local photoresist manufacturers in my country.

Industrial analysts said that compared with developed countries, my country’s photoresist market started late, with low self-sufficiency rate and poor overall technology in the industry. There is a big gap between the level and product quality and the international advanced level. In addition, my country’s photoresist products are mainly concentrated in the mid-to-low-end market, and high-end products are highly dependent on imports. In the future, as the Chinese government’s support continues to increase and corporate R&D technologies continue to improve, the localization rate of my country’s photoresist market is expected to increase.
