InSb Photodiodes (Review, Part II)

Analyzed have been the most important technological operations used for preparing the diffusion InSb photodiodes, namely: chemical-mechanical and chemical-dynamic polishing the surface of substrates, passivation of photodiode active area and methods of its realization, diffusion of cadmium as an acceptor impurity. The methods of manufacturing the diffusion InSb p-n junctions, in which the total dark current is determined by summing the generation-recombination and diffusion components have been described in details. The published data on manufacturing technology of InSb photodiodes have been generalized.

Keywords: InSb photodiode, passivation, chemical etching, sulphidation, cadmium diffusion.
