Title:
超格子量子井戸赤外線検出器
Document Type and Number:
Japanese Patent JP2013539053
Kind Code:
A
Abstract:
In at least one embodiment, an infrared (IR) sensor comprising a thermopile is provided. The thermopile comprises a substrate and an absorber. The absorber is positioned above the substrate and a gap is formed between the absorber and the substrate. The absorber receives IR from a scene and generates an electrical output indicative of a temperature of the scene. The absorber is formed of a super lattice quantum well structure such that the absorber is thermally isolated from the substrate. In another embodiment, a method for forming an infrared (IR) detector is provided. The method comprises forming a substrate and forming an absorber with a plurality of alternating first and second layers with a super lattice quantum well structure. The method further comprises positioning the absorber about the substrate such that a gap is formed to cause the absorber to be suspended about the substrate.
