Polyimides
Our Polyimide and Polybenzoxazole products are specialty stress relief coatings used as a protective layer or "buffer coat" before packaging or redistribution layer:
- Buffer coat layers provide protection to finished die during backgrind, singulation and assembly processing resulting in improved packaged yields and increased reliability lifetime performance.
- Redistribution layer applications enable the most advanced packaging designs.
Features and benefits:
- Broad product portfolio specifically engineered for stress relief and RDL applications
- Large process window enables robust processing
- i-line / g-line / broadband sensitive products, compatible with all exposure tools
- Fast photospeed for higher throughput and higher equipment capacity
- Superior resolution - 2 micron resolution in a 9 micron softbaked film, aspect ratios up to 3.0
- Self priming - excellent adhesion
- Excellent mechanical properties
- Cured film thickness range up to 50 microns
- Full line of complementary ancillary products
