Abstract
In one embodiment, an infrared (IR) sensor has a flexible beam connected between two anchors supported on a substrate. The beam is mechanically coupled to a plate that has an IR-absorbing layer and is adapted to transfer the IR-induced heat to the beam. The heat transfer causes the beam to deform and move the plate with respect to the substrate. The motion of the plate is detected electrically or optically to quantify the amount of IR radiation received by the plate. The beam, anchors, and plate are formed from a planar layer of material that is supported at a specified offset distance from the substrate. During fabrication, certain portions of the planar layer are removed to define the beam, anchors, and plate.
