Latest Patents

Gupta's latest patents include a high power unipolar FET switch and a high power rectifier. The high power unipolar FET switch features an N− drift layer and a layer of metal that contacts the drift layer via an ohmic contact to provide a drain connection for the FET. Each switch cell is designed with a pair of trenches recessed into the drift layer, separated by a mesa region. The structure operates as a "normally-off" device, allowing for fast switching speeds with very low switching losses.

The high power rectifier device consists of an N− drift layer on an N+ layer, with trench structures recessed into the drift layer. These structures are designed to form Schottky contacts at the metal-mesa interface, enabling forward conduction when the barrier height is overcome. The unipolar structure of this device also provides low switching losses, facilitating high switching speeds while minimizing power dissipation during transitions.
