Latest Patents

One of his latest patents is a semiconductor device with integrated trench lateral power MOSFETs and planar devices. This innovation allows for the gate electrodes of a TLPM and planar devices to be formed by patterning a single polysilicon layer. Additionally, the drain and source electrodes of both the TLPM and planar devices are created using a common metal layer. This design enables electrical connections between the TLPM and planar devices without the need for wire bonding on a printed circuit board.

Another notable patent is for a trench lateral power MOSFET and a method of manufacturing the same. This semiconductor device can be produced through a simpler process compared to conventional lateral trench power MOSFETs designed for an 80V breakdown voltage. It features a lower device pitch and reduced on-state resistance per unit area than traditional lateral power MOSFETs. The gate oxide film is formed thinly along the lateral surfaces of a trench, with a thicker layer along the bottom surface achieved through selective oxidation.
