Latest Patents
One of GuoHao Cao's latest patents is titled "Semiconductor device and method of fabricating same." This patent discloses a method that includes forming a plurality of gate electrodes at predetermined intervals on a semiconductor substrate's surface. The method also involves forming spacers on the sidewalls of the gate electrodes and depositing an interconnection layer conformally on the substrate. Selective etching of the interconnection layer is performed, ensuring that portions remain intact between adjacent gate electrodes, ultimately leading to the formation of electrical contacts.
Another notable patent is for a "Lateral double-diffused MOSFET and fabrication method thereof." This patent outlines a method for forming a Lateral Double-Diffused MOSFET (LDMOS). The process begins with providing a semiconductor substrate of a first conductivity type and forming a shallow trench isolation structure. The method includes ion implantation to create a drift region of a second conductivity type and forming a body region on one side of the drift region. A gate structure is then formed on the substrate, extending to both the body region and the shallow trench isolation region.
