Abstract
Abstract An infra-red radiation detector comprising an n-type semiconductor block on which are disposed in the form of projections small elementary p-type semi-conductor blocks, thereby creating a matricial network of elementary junctions, wherein the sensitive face of said detector is the free face of said n-type semiconductor block which is parallel to the plane of the elementary junctions.

An infra-red radiation detector comprising an n-type semiconductor block on which are disposed in the form of projections small elementary p-type semi-conductor blocks, thereby creating a matricial network of elementary junctions, wherein the sensitive face of said detector is the free face of said n-type semiconductor block which is parallel to the plane of the elementary junctions.
Claim 3
Dependent Claim
72 words
A detector according to claim 1, wherein the connecting wire common to all the elementary detectors is secured to the n-type semi-conductor block outside the sensitive surface of the detector, and the connecting wire pertaining to each elementary detector is secured to the p-type region by soldering to the outer face of the projections, which outer face is parallel to the plane of the junctions and is entirely covered by said solder.
Claim 4
Dependent Claim
35 words
