Abstract:
1. A coatable resin solution for forming a coating on a substrate, such as a wafer or electronic device, the resin solution comprising: a silsequioxane-based resin comprising a hydride component present in a mole fraction between 0.40 to 0.90 and at least one photo-curable component up to a mole fraction of 0.40 for the photo-curable component, the hydride component characterized by units of —(HSiO at least one initiator selected as one from the group of a free-radical initiator, a cationic initiator, and a combination or mixture thereof; and an organic solvent; wherein the resin solution is capable of forming a coating when applied to the surface of a substrate that is photo-patternable and developable as a dielectric material upon exposure to ultraviolet radiation; wherein the silsesquioxane-based resin does not further comprise an organo-siloxane component characterized by units of —(R
