Abstract

A method for making an electrode on a desired region of a thin film semiconductor layer having a junction therein and deposited on a conductive surface comprising the steps of applying an electrical pulse signal across the semiconductor layer at the desired region to lower the resistivity of the region and then forming an electrode film on the desired region of said semiconductor layer opposite said conductive surface, is disclosed. In one alternative embodiment, an electrode film is formed on the thin film semiconductor layer and thereafter an electrical pulse signal is applied across the semiconductor layer at the desired region to lower the resistivity of the region.
