Introduction

Raghuveer Vankayala Gupta is an accomplished inventor based in Austin, TX. He has made significant contributions to the field of semiconductor technology, holding a total of 3 patents. His work focuses on advanced manufacturing methods for power semiconductor devices.

Latest Patents

One of Gupta's latest patents is a method for manufacturing a super-junction power semiconductor device. This innovative method involves forming a recessed shield electrode in a trench within a semiconductor layer of a substrate. The trench is lined with a first oxide layer, and the process includes the removal of the electrically conductive material to expose the first oxide layer on the sidewalls. This leads to the formation of openings at the top part of the shield sidewalls, followed by the creation of a second oxide layer that fills these openings. The final steps involve forming a gate dielectric over the shield electrode and depositing conductive material to create the gate electrode of the MOSFET.

Another notable patent by Gupta is for vertical bi-directional switches. This device features first and second conductive gates within a semiconductor layer, each with vertical gate oxides on their sidewalls. The design includes heavily doped regions of a first conductivity type adjacent to each conductive gate, along with a doped region of a second conductivity type that extends laterally between the two heavily doped regions. This innovative approach enhances the functionality and efficiency of bi-directional devices.
