ElsquareS Completes PSPI Reliability Testing with US Glass Substrate Client

ElsquareS, a semiconductor component material company jointly established by Leaders Cosmetic and LTC, announced on the 20th that it has successfully completed the development of photosensitive polyimide (PSPI) material to be used in the production line of glass core substrate products for semiconductor packaging produced by its U.S. glass substrate customer. The product recently completed reliability testing, proving its potential for commercial use.

PSPI is used as a coating layer for glass core substrates in semiconductor packaging, playing a key role in protecting the product surface, preventing corrosion and oxidation. In particular, ElsquareS's PSPI offers a new alternative in the advanced materials market, which has been monopolized by Japan, securing global competitiveness.

ElsquareS's PSPI does not use perfluoroalkyl substances (PFAS), meeting environmental regulations of the European Union and the United States, and boasts high sensitivity, low dielectric loss, excellent heat resistance, and film properties. Additionally, based on technology verified in the display sector, it is applied to the advanced semiconductor packaging field, providing differentiated quality and performance compared to existing materials.

The U.S. glass substrate customer plans to begin mass production using this material starting next year, and it is expected that sales of ElsquareS's PSPI will increase significantly as a result.
