Latest Patents
One of Cheng-Hui Tung's latest patents is titled "Trench metal oxide-semiconductor transistor and fabrication method thereof." This invention provides a fabrication method for a trench metal oxide-semiconductor (MOS) transistor. The process involves forming gate trenches in the epitaxial layer and implanting impurities of a first conductive type. A polysilicon pattern is then created to fill the gate trenches, followed by the implantation of impurities of a second conductive type to form a well. The method also includes the formation of source regions adjacent to the gate trenches through a series of doping processes.
Another notable patent is "Semiconductor structure and fabrication method thereof." This invention outlines a semiconductor fabrication process that defines an auxiliary structure with spaces in the oxide layer. This design prevents the conductive material in the spaces from being removed by etching, thereby reducing the number of required masks and lowering production costs.
