Latest Patents

One of Zimmermann's latest patents is a 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 involves 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, allowing for the fabrication of infrared detector arrays within the defined regions. The final step involves separating the fabricated arrays at the cleavage lines to create individual buttable infrared detector arrays.

Another significant patent focuses on improving the interconnect reliability of focal plane arrays. This invention describes an improved structure for interconnecting focal plane arrays, where a first body, comprising a detector array, is connected to a second body that includes semiconductor electronics. The interconnection apparatus utilizes materials with different coefficients of expansion to enhance reliability. In one aspect, the interconnect columns are made of indium, while the first body is made from materials such as CdTe and HgCdTe, and the bonded layer is primarily composed of copper.
