Latest Patents
One of Pei's latest patents is titled "Method for making self-electro-optical device and devices made thereby." In this patent, applicants have discovered a method of reproducibly fabricating SEED devices that have an enhanced contrast ratio. This is achieved by adjusting the thickness of a cap layer in relation to the reflector stacks to form a Fabry-Perot cavity. Specifically, after the growth of the reflector stack and the quantum wells, the optical thickness of the region above the reflector stacks is measured without breaking vacuum. Based on this measurement, a cap layer is grown to a sufficient thickness to form a Fabry-Perot cavity for light of the desired wavelength. The result is a device with enhanced contrast between the 'on' and 'off' states, allowing the state to be directly read without differential processing.
Another significant patent is for "Planar FET-SEED integrated circuits." In this innovation, FETs and quantum well diodes are combined on the same semi-insulating substrate while providing the FETs with protection from spurious voltages. A deeply buried P region in the semi-insulating substrate is partitioned by a high resistivity proton implanted region. This configuration provides both the P region of the quantum well diode and an isolating buried P layer for the FETs.
