Photovoltaic infrared radiation detector with independent three-dimensional conducting grid
First Claim
1. Photovoltaic infrared radiation detector comprising, on a front face of a substrate transparent to the radiation considered, a stack of layers made of absorbent semi-conducting materials, a network of channels confining pixels in the stack of layers, and an insulating layer covering at least the bottom and side walls of the channels, detector comprising an electrically conducting layer covering the insulating layer on the bottom and on the side walls of the channels and electrically independent from the semi-conducting materials so as to be totally electrically insulated from the semi-conducting materials by said insulating layer.

Abstract
On a front face of a substrate transparent to the radiation considered, pixels are confined in a stack of absorbent semi-conducting material layers by a network of channels. An insulating layer covers the bottom and the side walls of the channels. An electrically conducting layer covers the insulating layer on the bottom and on the side walls of the channels confining at least a part of the pixels. The conducting layer can be voltage polarized.
