Thermal electromagnetic radiation detector comprising an absorbent membrane fixed in suspension
First Claim
1. Thermal electromagnetic radiation detector comprising an absorbent membrane fixed in suspension by thermally insulating support means onto a front face of a substrate comprising at least two electric connection terminals electrically connected to the membrane, the support means comprising at least one support part arranged between the substrate and membrane and having at least one base end and a raised zone, detector wherein the base end of said support part is fixed to a top part of a conducting pillar having a base fixedly secured to an electric connection terminal, a substantially flat zone of a bottom face of the membrane being directly in contact with the raised zone of the support part, and the support part is formed by a bridge having a second base end fixed to a top part of a second pillar, the raised zone being formed by a middle part of the bridge.

Abstract
The absorbent membrane of the detector is fixed in suspension by at least one thermally insulating support part onto a front face of a substrate comprising at least two electric connection terminals electrically connected to the membrane, for example by means of conducting layers. The support part has at least one base end and a raised zone. The base end is fixed to a top part of a conducting pillar having a base fixedly secured to one of the electric connection terminals. A substantially flat zone of a bottom face of the membrane is directly in contact with the raised zone of the support part. The support part is preferably formed by a bridge having a second base end fixed to a top part of a second pillar, the raised zone being formed by a flat middle part of the bridge.
