Patent ID: 8860166

Claim:
A photodetector array comprising: a semiconductor substrate; an array of Geiger mode avalanche photodiodes on the semiconductor substrate configured to detect radiation, each Geiger mode avalanche photodiode comprising an anode contact, a cathode contact, an output contact electrically insulated from said anode and cathode contacts, a semiconductor layer, a front side metallization layer on the semiconductor layer, and at least one shield structure in said semiconductor layer capacitively coupled to said semiconductor layer and coupled to said output contact; a first connection lead defined by a common cathode contact of the array photodiode cathode contacts; a second connection lead defined by a common anode collecting grid contact, patterned in the front side metallization layer of the semiconductor layer, connecting in common the anode contacts of the array photodiodes; and an array output defined by the array photodiodes output contacts connected in common.
