Latest Patents

Youngchul Choi holds a patent for a "Fabrication method of forming silicon carbide MOSFET." This patent outlines a comprehensive fabrication method that includes several critical steps. The process begins with providing a semiconductor substrate, followed by the formation of a P-well region through implantation. A spacer is then placed on the sidewall of the P-well mask, and the P-well region is implanted to create an N-plus layer. Subsequently, a P-plus mask is used to implant the semiconductor substrate, forming a P-plus layer. The method continues with the formation of a gate oxide layer, a poly gate, and a first interlayer dielectric layer on the substrate. A second interlayer dielectric layer is then disposed on the sidewall of the poly gate and the first interlayer dielectric layer. Finally, a metal layer is applied to cover both interlayer dielectric layers. This innovative method enhances the performance and efficiency of silicon carbide MOSFETs.
