Asahi Kasei has officially announced the development of a new photosensitive polyimide (PSPI) film engineered specifically to meet the evolving demands of the semiconductor industry. As the sector shifts toward panel-level packaging, this new material is designed to improve manufacturing efficiency and overall yield for next-generation electronic components.
The development leverages the company’s established expertise in liquid PSPI and dry film photoresist technologies. By combining these capabilities, the new product facilitates a streamlined lamination process suitable for large square panels. This technical advancement allows for uniform application, which is a critical factor for manufacturers aiming to scale production.
The industry’s move toward high-density integration necessitates materials that can accommodate a greater number of insulating layers. The newly engineered PSPI film advances packaging by serving as an effective solution for redistribution layers and package substrate insulation.
Furthermore, when utilized alongside the company’s existing dry film photoresist series, the material enables the formation of fine circuit patterns through film lamination. Ongoing development also includes compatibility with solutions designed for high-aspect-ratio copper pillar formation, a requirement for sophisticated three-dimensional semiconductor packaging.
The product is currently undergoing evaluation by customers, with commercial availability expected in the near future. As the demand for high-performance semiconductor packaging continues to expand, this material is positioned to support the required precision and scale.
