Title: Yi Xuan: Innovator in Semiconductor Technology
Introduction
Yi Xuan is a prominent inventor based in West Lafayette, IN (US), known for his contributions to semiconductor technology. He holds a total of 4 patents, showcasing his innovative approach to the field.
Latest Patents
Among his latest patents, Yi Xuan has developed methods for INP-based transistor fabrication. These methods involve forming structures that include InP-based materials, such as a transistor operating as an inversion-type, enhancement-mode device. A dielectric layer may be deposited by atomic layer deposition (ALD) over a semiconductor layer that includes indium (In) and phosphorus (P). Additionally, a channel layer may be formed above a buffer layer that has a lattice constant similar to that of InP, with the buffer layer being formed over a substrate that has a different lattice constant. Another significant patent is for an optical coupler, which is a semiconductor photonic device that includes a substrate, facets, and optical couplers associated with the facets. Each optical coupler can couple an electromagnetic field incident on the respective facet towards the substrate as the electromagnetic field proceeds into the semiconductor photonic device. In some examples, each coupler has waveguides extending in a longitudinal direction and at least partly encapsulated within corresponding cladding layers.
