Introduction

Se Puan Yu is a notable inventor based in Schenectady, NY (US), recognized for his contributions to semiconductor technology. He holds a total of 3 patents that showcase his innovative approach to electronic devices.

Latest Patents

One of his latest patents is the Vertical Field Effect Transistor. This invention features an interdigitated field effect transistor designed for high power and high frequency applications. It has a vertical configuration with current flow that is essentially normal to the surface, contrasting with planar devices where current flow is parallel to the surface. Each channel region shares the same conductivity type as the source and drain regions, structured in a mesa format surrounded by gate metallization. This design allows the gate metal to form an electronically blocking contact to the channel semiconductor, resulting in a natural strip line configuration.

Another significant patent is the Avalanche Memory Triode and Logic Circuits. This invention involves a semiconductor-controlled avalanche triode that operates at microwave frequencies. It is activated by a narrow pulse and remains conducting due to the positive feedback effect of returning carriers in the base region until it is turned off by an opposite polarity narrow pulse. The applications of this technology include fast switches, memory devices, and various logic circuits such as logic gates and shift registers. These memory and logic devices are characterized by their speed, low power requirements, and simplicity, as they can be made with one triode per memory and are integrable using silicon.
