1 | Market Overview
Photosensitive polyimides (PSPI) for the semiconductor market are advanced functional materials utilized for precise patterning and high-performance insulation in integrated circuits (ICs). These materials provide high thermal stability, low dielectric constants, and compatibility with lithographic techniques, making them essential in modern chip fabrication—especially for advanced nodes, logic chips, and memory devices.
As transistor densities increase and interconnect layers become more complex, PSPI materials are being used in key roles such as interlayer dielectric coatings, buffer layers, wafer passivation, and chip stacking. Their ability to be photodefined simplifies multi-step processes and supports ongoing scaling trends.
