ABSTRACT:
A method of making an ohmic content to a thin film of a II-VI compound semiconductor. The contact is made by etching the film with an acidic solution and thereafter treating the etched surface with an alkaline solution. A layer of copper 5 to 50 angstroms thick is deposited on the etched and treated surface and covered by a different metal. The contact may be heat treated to improve its performance.
