Latest Patents

One of McDonald's notable patents is titled "Method for fabricating buttable epitaxial infrared detector arrays." This invention provides a method for fabricating buttable infrared detector arrays by dimensionally controlled cleaving of a single crystal wafer substrate having well-defined cleavage planes. The process begins with cleaving the single crystal wafer substrate along its natural cleavage planes to form a plurality of cleavage lines that define rectangular detector array regions. A layer of infrared-sensitive material is then epitaxially grown on the cleaved substrate. Infrared detector arrays are fabricated on this layer within the defined regions. Finally, the arrays are separated at the cleavage lines to create individual buttable infrared detector arrays. This innovative approach enhances the efficiency and effectiveness of infrared detection.
