Abstract

A method of forming a conductive film on an insulating region of a substrate wherein a surface of the insulating region formed on the substrate is activated by irradiating the surface with electrons, ions or light. Next, a metal film pattern constituting, for example, an electrical interconnection, is deposited on the surface by applying a selective chemical vapor deposition process using a metal halide gas.
