JSR's WPR series photosensitive dielectric materials come in both positive tone (NQD based) and negative tone (chemically amplified) to allow process flexibility. In addition, JSR's unique proprietary design incorporates surface treated rubber nano particles to provide excellent physical and mechanical properties. Along with high sensitivity, resolution, and long shelf life, these materials are well suited to meet the current as well as next generation packaging challenges.
