Latest Patents
Among his recent inventions, one notable patent is the "Method of fabricating turning mirror using sacrificial spacer layer and device made therefrom." This invention outlines a sophisticated method for fabricating a waveguide by utilizing a sacrificial spacer layer. The process begins by fabricating an underlying optical semiconductor structure, followed by etching a trench that produces an L-shaped structure. A sacrificial spacer layer is then deposited in this trench, facilitating the creation of a waveguide on that layer. The use of a mask layer to angle the vertex of the L-structure is an innovative step, and the later removal of specified portions of the sacrificial spacer layer creates essential air gaps, optimizing the relationship between the waveguide and the sidewalls of the trench within the optical semiconductor.
