Latest Patents

One of his latest patents is the Asymmetrical Field Controlled Thyristor. This innovative device features a base that is doped more lightly near the gate than near the anode, resulting in a low forward voltage drop, high blocking gain, and fast switching speed at any given forward blocking voltage rating. The high resistivity region around the gate area allows the device to pinch off anode current flow at zero gate bias, and a small forward gate voltage can trigger the device into conduction. Additionally, the high resistivity of the channel area between gates provides DC blocking gains greater than 60. This device can be fabricated using conventional planar processing techniques.

Another notable patent is the Field-Controlled Bipolar Transistor. This transistor is characterized by a bidirectional voltage blocking capability between the collector and emitter electrodes. It comprises a semiconductor substrate with base, emitter, and collector regions formed within it. The base region is of one conductivity type, while the emitter and collector regions are of the opposite conductivity type. A gate region, also of opposite conductivity type, is formed in the substrate. When the junction between the gate region and the substrate is reverse-biased, a depletion region forms, pinching off current flow between the emitter and collector regions. This design allows the transistor to block high voltages in both forward and reverse directions while maintaining normal bipolar transistor characteristics in the forward direction.
