Abstract:
A method for producing a bolometric detector comprising: producing a stack, on an interconnect level of a read-out circuit, comprising a sacrificial layer positioned between a carrier layer and an etch stop layer, the sacrificial layer comprising a mineral material; producing a conducting via passing through the stack such that it is in contact with a conducting portion of said interconnect level; depositing a conducting layer onto the carrier layer and the via; etching the conducting layer and the carrier layer, forming a bolometer membrane electrically connected to the via by a remaining portion of the conducting layer that covers an upper part of the via; elimination of the sacrificial layer by selective chemical etching, and such that the membrane is suspended by the via.

Claim (Index 1):
A method for producing a bolometric detector comprising at least:\n producing a stack of layers on an electrical interconnect level of an electronic read-out circuit of the detector, the stack comprising at least one sacrificial layer positioned between a carrier layer and a first etch stop layer, the first etch stop layer being positioned between the sacrificial layer and said electrical interconnect level, and the sacrificial layer comprising at least one mineral material capable of being selectively etched relative to the carrier layer and the first etch stop layer; producing at least one electrically conducting via passing through at least the stack of layers such that at least one electrically conducting material of the via is in contact with at least one electrically conducting portion of said electrical interconnect level connected to the electronic read-out circuit; depositing at least one electrically conducting layer onto the carrier layer and the via; etching the electrically conducting layer and the carrier layer, forming a bolometer membrane electrically connected to the via by at least one remaining portion of the electrically conducting layer that covers at least one upper part of the via; eliminating the sacrificial layer by chemical etching to which the first etch stop layer and the carrier layer are resistant, and such that the membrane is suspended by means of the via.
