Thick film photoresist, also known as thick layer photoresist, is a high-performance photoresist. It refers to a photoresist with a higher film thickness after coating in the photolithography process. Thick film photoresist has the advantages of strong heat resistance, high resolution, high precision, high resolution, and good stress buffering. It is widely used in wafer packaging, liquid crystal display, 3D NAND memory chips, MEMS micro-electromechanical chips and other fields. .

The thick film photoresist industry has good development prospects, but production is difficult. Poor film thickness uniformity, easy cracking, poor shape, poor heat resistance, and poor film peelability are common problems in the production process of thick film photoresist. In the future, as local companies continue to increase investment in research and development, the maturity of my country’s thick film photoresist technology is expected to increase.

According to the “2023-2028 China Thick Film Photoresist Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center It shows that thick film photoresist has a wide range of applications. In the field of wafer packaging, thick film photoresist can be used in the thick film photolithography process, which can effectively improve the density level of wafer packaging; in the field of liquid crystal display, KrF light source thick film photoresist can be used to produce LCD liquid crystal displays. Benefiting from the accelerated development of downstream industries, the global thick film photoresist market continues to expand, reaching US$150 million in 2022.

The thick film photoresist industry has high technical barriers, and the global market is mainly concentrated in Europe, the United States, Japan and other countries. eChem Solutions Japan Co., Ltd., Japan’s Sumitomo Chemical, Japan’s Shin-Etsu Chemical Industry Co., Ltd. (Shin-Etsu), Germany’s Micro Resist Company, Germany’s Allresist GmbH Company, Germany’s Suss Company, etc. are global thick film photoresists. Major manufacturing companies, among which Japanese companies account for nearly 60% of the global market. In the early stages of industry development, my country’s thick film photoresist import dependence was high, and Japan was my country’s main importing country.

In recent years, with the continuous breakthroughs in technological innovation level of local enterprises, the localization process of my country’s thick film photoresist market has accelerated. The main thick film photoresist manufacturers in my country include Shanghai Xinyang Semiconductor Materials Co., Ltd., Tongcheng New Materials Group Co., Ltd., Shanghai Plite Composite Materials Co., Ltd., Shenzhen Rongda Photosensitive Technology Co., Ltd., etc. Shanghai Xinyang is my country’s leading thick-film photoresist company. It focuses on the R&D, production and sales of dry ArF photoresist and KrF photoresist. It has independent research and development capabilities for KrF (248nm) thick film photoresist. Currently, the company We are actively promoting the research and application of KrF thick film photoresist for storing 128-layer 3D flash memory.

Industry analysts said that thick film photoresist has the advantages of strong heat resistance, high resolution and high precision, and is widely used in many fields. It is widely used and has good industry development prospects. Due to factors such as high technical barriers, my country’s high-quality thick film photoresist production capacity is low, and demand is highly dependent on imports. It is expected that in the future, as local companies continue to exert their efforts, the localization process of my country’s thick film photoresist market will accelerate.
