Abstract:
1. A structure, comprising: a porous cross-linked layer of a silsesquioxane polymer on a substrate, said porous cross-linked layer comprises three monomers of the structural formulas (1), (7) and (3): wherein R wherein R wherein m, q, and o, represent the mole percent (mol %) of repeating units with m+q+o equal to or greater than about 40 mol %; said porous cross-linked layer including an additive silsesquioxane polymer of structure (5): wherein R wherein s is an integer between about 10 and about 1000; a trench in said porous cross-linked layer; an electrically conductive material filling said trench and contacting said substrate in a bottom of said trench; an additional porous cross-linked layer of an additional silsesquioxane polymer directly on a top surface of said porous cross-linked layer; an additional trench in said additional porous cross-linked layer, a top of said trench open to a bottom of said additional trench; and said electrically conductive material additionally filling said additional trench.
