Latest Patents

Yao-Chi Chang holds a patent for a "Method for forming a trench power metal-oxide semiconductor transistor." This invention outlines a method of forming a trench power MOS transistor over a semiconductor substrate. The process begins with the formation of a pad oxide layer on the substrate, followed by the creation of a masking layer. The trench pattern is then defined, and the substrate is etched to form the trench structure. A gate oxide layer is applied to the trench's outer surface, and a conducting layer is filled into the trench to serve as the gate structure. Doped areas are formed in the substrate to act as source structures, and sidewall spacers are created on the masking layer and pad oxide layer. Finally, a field oxide layer is formed on the conducting layer.
