Abstract
A solid relay having a light emitter and a photodetector and a method of producing the same are disclosed. A planer thyristor, photodiode, phototransistor or similar photodetector is formed on an Si substrate or wafer. The surface of the photodetector is covered with an SiO.sub.2, PSG (Phospher-Silicate Glass) or similar transparent insulation film. An ITO (Indium Tin Oxide) or similar transparent film, an organic thin film and a metal electrode are sequentially formed on the transparent insulation film, constituting a light emitter. The laminate is separated from the wafer in the form of a chip by dicing. The chip is bonded to a lead frame, connected to the leads of a lead frame by wire bonding, and then sealed with epoxy resin or similar resin.
