Abstract
A device is disclosed including a substrate and a floating blinded infrared detector and/or a shunted blinded infrared detector. The floating blinded infrared detector may include an infrared detector coupled to and thermally isolated from the substrate; and a blocking structure disposed above the infrared detector to block external thermal radiation from being received by the infrared detector; and wherein the blocking structure comprises a plurality of openings. The shunted blinded infrared detector may include an additional infrared detector coupled to the substrate; an additional blocking structure disposed above the infrared detector to block external thermal radiation from being received by the additional infrared detector; and a material that thermally couples the additional infrared detector to the substrate and the additional blocking structure. Methods for using and forming the device are also disclosed.
