Latest Patents

Katsuya's latest patents showcase his innovative methodologies in manufacturing high voltage MOSFET semiconductor devices. The first patent, titled "Method for Manufacturing a High Voltage MOSFET Semiconductor Device with Enhanced Charge Controllability," introduces a high voltage MOSFET device featuring an n-well region equipped with a p-top layer of opposite conductivity. This configuration is designed to improve device characteristics by implanting the p-top layer through a thin gate oxide and diffusing it into the silicon during the source/drain anneal process. This technique eliminates the growth of field oxide on the top of the extended drain region, allowing for a shallow and controlled p-top, which results in low on-resistance while maintaining the desired breakdown voltage.

His second patent, "Method for Manufacturing a High Voltage MOSFET Device with Reduced On-Resistance," involves a high voltage MOSFET device with a well region that contains two areas: one with a high dopant concentration and the other with a low dopant concentration. This innovative design enhances the breakdown voltage while minimizing on-resistance during the device's operational state. Additionally, a p-top layer is positioned on the top surface of the well region, which is driven into the well through high-temperature annealing in an inert atmosphere, further optimizing device performance.
