ABSTRACT:
Method of making a semiconductor device which includes applying a solution of a heterocyclic ring-containing polymer in an organic solvent to a desired surface of a semiconductor body and removing the organic solvent from the solution by heat thereby to form a coating of a polymer on the surface, wherein the polymer is a reaction product of a diamine represented by the formula: ##STR1## with a tetracarboxylic acid or anhydride of it. Since the coating exhibits good thermal stability and good electrical properties when applied to the surface of the semiconductor, it is useful as a passivating film.
