METHOD OF MAKING PHOTODETECTOR ARRAY Russian patent published in 2008 - IPC H01L31/18 

Abstract RU 2340981 C1

FIELD: physics.

SUBSTANCE: present invention pertains to the technology of making an array of photosensitive elements with p-n-junctions infrared band micro-photoelectronics. The method of making an array of photodiode elements with n+-p-junctions based on cadmium-mercury telluride involves surface passivation by epitaxy of cadmium telluride dielectric, photolithography, chemical etching of n+-p-junction locations by 2-3 mcm inside the cadmium-mercury telluride and ion implantation or iron bombardment in plasma.

EFFECT: proposed method allows for obtaining photodiodes with small dark current value and high quantum efficiency, providing for high detection capacity.
