Claim Text:
1. A semiconductor device comprising: a substrate having an upper surface that defines a sensing region; a patterned conductive layer on the upper surface of the substrate; a fixed beam structure formed of a first conductive material and supported at a first level above the sensing region, the fixed beam structure including a first fixed beam support and a second fixed beam support that extend upwardly from the upper surface of the substrate to position the fixed beam structure at the first level above the sensing region, the fixed beam structure being electrically connected to the patterned conductive layer by the first and the second fixed beam supports; and an absorber structure formed of a second conductive material and supported above the fixed beam structure at a second level above the sensing region, the absorber structure including a single pillar support that extends upwardly from the fixed beam structure to position the absorber structure at the second level above the sensing region, wherein the first fixed beam support extends upwardly from the upper surface of the substrate at a first position located on a first side of the sensing region and the second fixed beam support extends upwardly from the upper surface of the substrate at a second position on a second side of the sensing region that is opposite from the first side, the first and the second positions being spaced laterally apart from each other such that a central portion of the fixed beam support is suspended over the sensing region between the first fixed beam structure and the second fixed beam structure, the pillar support of the absorber structure extending upwardly from the central portion of the fixed beam structure.
