A process is described in which planar photodiodes are formed by diffusing lead into p-type Pb.sub.0.8 Sn.sub.0.2 Te single crystal material.

Method of manufacture of photodiode

An improved diode array and method of manufacture is provided by the diffon of cadmium from an indium-cadmium alloy through a silicon diode mask into bulk indium-antimonide to form a planar structure.

Planar indium antimonide diode array and method of manufacture

Photodiode and method of manufacture

A layer of indium is deposited as small islands on a photosensitive material. The islands and the material not covered by the islands are bombarded with ions to cause sputtering of the islands and the material. When the islands have been sputtered away, the material has a surface consisting of cones and pyramids. Such a surface is more efficient at absorbing photons than is a smooth surface.
