First, a fun fact: Making chips is like baking a cake, where the photolithography machine is the oven and the photoresist is the baking paper. Without the paper, the cake will burn at the bottom. Currently, 90% of the world’s high-end “baking paper” is printed in Japanese, and the finest types are measured in individual … Read more

Photoresist first appeared in human history nearly 200 years ago.At the Harry Ransom Center at the University of Texas at Austin, a world-class humanities and arts archive, there is a metal plate quietly leaning in one of the display cases, measuring 20 centimeters long and 16.5 centimeters wide.Most of the plate’s surface is shadowed, with … Read more
Our public account has surpassed 500 followers in just over a month. We will continue to work hard and share more valuable content. Happy National Day! The key material in the photolithography process is photoresist, which mainly consists of organic resins, photosensitive compounds, and solvents. Additionally, it needs to be resistant to corrosion and ion … Read more
The quality of semiconductor materials directly impacts the manufacturing of semiconductor products. For instance, the performance of photoresists can directly affect the performance and integration of chips, determining the feasibility of photolithography processes. Therefore, selecting high-quality semiconductor material suppliers is crucial. Companies like JiuRi New Materials and Nanda Optoelectronics not only possess strong capabilities but … Read more
Photoresist, also known as photoresist, is a non-conductive photosensitive material that transfers patterns from a photomask onto a wafer based on the principle of changing properties when exposed to light. After development, the unexposed photoresist needs to be washed away with a stripping solution to expose the substrate for subsequent etching. Currently, most stripping solutions … Read more
Introduction: She was rejected by a chip factory just for saying “photoresist is a photosensitive material” Last week, I had milk tea with Xiaoxia, who recently switched jobs. She held her iced coconut milk and sighed, “Sister, I interviewed at XX chip manufacturing company, and when the HR asked me ‘What is photoresist?’, I replied … Read more
As the “invisible champion” of chip manufacturing, the domestic substitution process of semiconductor photoresists is directly related to the security and competitiveness of China’s semiconductor industry chain. This report focuses on three core types of photoresists: KrF, ArF, and EUV, comprehensively analyzing technical difficulties, the current status of domestic substitution, and future breakthrough paths. It … Read more
Child of the Sino-US Trade Era On September 14, 2020, late at night, Hsinchu, Taiwan. TSMC’s factory was brightly lit, and the machines on the production line were still running at high speed, but there was an unusual tension in the air. Just a few hours earlier, the U.S. Department of Commerce announced: After September … Read more
