Everlight Chemical's patented EverPI® P Series Positive PSPI is an advanced chip-making material integrating both photoresist and insulation functions. It delivers exceptional resolution, achieving 3–5 µm micro-holes with near-vertical sidewalls to maximize routing density facilitating smaller chips. Uniquely on the market, it achieves 180°C low-temperature curing, reducing energy consumption by 20% while maintaining superior chemical resistance. Unlike traditional materials that tend to be fragile, its patterns remain intact throughout etching, protecting heat-sensitive components and improving yields. Free of toxic NMP and compatible with water-based developers, it ensures eco-friendliness and broad equipment compatibility. With over 30 years of expertise in electronic chemicals, we pioneered photoresist mass production for leading fabs in Taiwan. As a critical local supplier committed to rapid customization and faster verification, we continue to strengthen supply chain resilience.
