Patent ID: 8866082

Claim:
An electromagnetic radiation detector intended to operate around a wavelength λp contained within a spectral band of interest that is defined between λmin and λmax, comprising a plurality of micro-sites, each of the micro-sites including a membrane that is sensitive to radiation at least in the spectral band of interest and each of the micro-sites being provided in a micro-cavity or micro-capsule defined by a substrate, by an upper wall used as a window that is transparent to said radiation in the spectral band of interest for at least some of said plurality of micro-sites and by side walls attached to the substrate and the upper wall, said membrane being suspended above the substrate by means of at least two support arms that include an electrically conducting layer, each of said support arms comprising an end mechanically attached to the substrate, wherein the ends of said support arms attached to the substrate are anchored in said side walls, and wherein the substrate and the side walls are made of successive layers that are formed directly upon each other by deposition.
