Latest Patents

One of his latest patents is a semiconductor device with improved protection from electrostatic discharge. This invention features a concentric polygonal metal-oxide-semiconductor field-effect transistor designed to avoid overlap between corners of the central drain diffusion and inner corners of the surrounding annular gate electrode. By reducing the gate electrode to separate straight segments or modifying the drain diffusion to a cross shape, the design minimizes electric field concentration in corner regions, thereby providing enhanced protection from electrostatic discharge.

Another notable patent is related to a semiconductor device and its manufacturing method. This method involves forming a gate insulating film on a P-type semiconductor layer and creating a gate electrode with slits. The process includes selectively implanting an N-type impurity into the P-type semiconductor layer using the gate electrode as a mask, followed by heat treatment to activate the impurity. This results in the formation of N-type low-density and high-density diffused layers, which are crucial for the device's functionality.
