Latest Patents

Richard Lai holds a patent for a "Method for forming shielded gate of MOSFET." This patent outlines a method that includes several steps: providing a semiconductor substrate with at least one trench, forming a bottom gate oxide region and a shielded gate poly region within the trench, and creating an inter-poly oxide region through high-temperature plasma deposition. The process also involves poly etching back and oxide etching back, ultimately leading to the formation of a gate oxide region and a gate poly region. By utilizing etching back processes instead of traditional chemical mechanical polishing, the manufacturing costs are significantly reduced. Additionally, the shielded gate structure effectively lowers gate charge, enhancing the overall performance of the MOSFET.
