KMSF® 1000 is a negative tone, polyimide-based photo-dielectric for use as an ultra-low stress buffer, passivation or protective layer. It exhibits excellent warpage control especially critical for thin and large diameter substrates used in backend/assembly processing due to its low shrinkage, very low tensile modulus, and low thermal cure requirement.


Applications: Stress buffer
Passivation and protective layers
