Patent ID: 7138630

Claim:
Bolometric detector comprising: a sensitive part having one or more layers of a bolometric sensitive material consisting of at least one of an amorphous silicon and a related alloy of the Si x Ge y C z type in which x+y+z=1, the resistivity of which varies with temperature, electrodes isolated from one another, the electrodes acting as infrared radiation absorbers and being in contact with the sensitive material over at least part of their surface, and regions of sensitive material not in contact with the electrodes having at least one corrugation oriented along a direction perpendicular to a plane of the sensitive part, each corrugation having exposed surfaces defined by the sensitive material; at least one support region for supporting the sensitive part positioning the sensitive part, and acting as an electrical conductor, in relation to a read circuit associated with the bolometric detector; and at least one thermal insulation structure electrically and mechanically connecting each support region to the sensitive part.
