Latest Patents

One of Lockwood's latest patents is the "Infrared detector hybrid array with improved thermal cycle reliability." This invention features a hybrid infrared focal plane array detector that utilizes a thinned detector layer and substrate, which are directly bonded to a conventional semiconductor readout integrated circuit substrate. The design allows the detector to function like a flexible membrane, responding elastically to thermal mismatches during cooling from room temperature to cryogenic operation temperatures. By adjusting the thickness of the detector substrate, Lockwood's innovation enables the creation of essentially unlimited hybrid detector sizes. Additionally, the detector layer and substrate can be segmented into sub-arrays, providing enhanced resistance to stress induced by thermal mismatches.

Another significant patent is the "Open-tube, benign-environment annealing method for compound." This invention presents an improved system and method for annealing indium antimonide ion implanted junctions within an open-tube benign annealing environment. The process involves a furnace with a hollow chamber maintained at a predetermined annealing temperature, where wafers of indium antimonide are inserted through a resealable airlock. A source of molten indium saturated with antimony is present to maintain desired partial pressures, while hydrogen gas continuously purges contaminants and maintains slight overpressure. After annealing, the wafer is cooled and prepared for subsequent processing steps.
