Abstract:
1. A method, comprising; (a) forming on a substrate, a layer of a photoactive formulation comprising: where wherein R (b) patternwise exposing said layer with ultraviolet light to generate an exposed layer; (c) baking said exposed layer to cross-link said silsesquioxane polymer in regions of said exposed layer exposed to said ultraviolet light to generate a baked layer; (d) developing said baked layer to remove portions of said baked layer not exposed to said ultraviolet light to form a first trench in a developed layer; (e) curing said developed layer to further cross-link said silsesquioxane polymer and form a patterned cured layer including said first trench; and (f) filling said first trench in said patterned cured layer with an electrically conductive material.
