    Abstract: An improved insulating layer is formed by applying to a suitable substrate an organic solution, prepared by reacting a aminoalkoxysilane monomer, an arylalkoxysilane or arylsilazane monomer and water in a solvent, and then heating the coated substrate under conditions so as to evaporate the solvent and form a layer of cured ladder-type silsesquioxane copolymer. The insulating layer, which demonstrates excellent planarizing and thermal stability characteristics, in particularly useful in semiconductor device applications.
