Latest Patents
Klepser's latest patents focus on Si/SiGe optoelectronic integrated circuits. These patents describe an integrated optoelectronic circuit and the process for making it, which incorporates a photodetector and a MODFET on a chip. The chip consists of a single-crystal semiconductor substrate, a buffer layer of SiGe graded in composition, a relaxed SiGe layer, a quantum well layer, an undoped SiGe spacer layer, and a doped SiGe supply layer. The photodetector can be a metal-semiconductor-metal (MSM) or a p-i-n device. Additionally, the detector may be integrated with an n- or p-type MODFET, or both in a CMOS configuration, with the MODFET potentially incorporating a Schottky or insulating gate. This invention addresses the challenge of producing Si-manufacturing-compatible monolithic high-speed optoelectronic circuits for 850 nm operation by utilizing epitaxially-grown Si/SiGe heterostructure layers.
