Introduction

Johnny K Sin is a notable inventor based in Hong Kong, CN. He has made significant contributions to the field of power integrated circuits and semiconductor devices. With a total of 2 patents, his work showcases innovative solutions to common challenges in electronics.

Latest Patents

One of his latest patents is for a power integrated circuit with latch-up prevention. This invention includes a substrate with an overlying epitaxial surface layer of opposite conductivity type. A semiconductor power device, such as a high-power diode or lateral MOS transistor, is located in the epitaxial layer and forms a p-n junction diode with the substrate. The design also features a separate semiconductor well region in the epitaxial layer, where low-power semiconductor circuit elements are formed. To minimize latch-up issues, the circuit is equipped with a collector region and an isolation region between the power device and the well region.

Another significant patent by Johnny K Sin is for lateral trench-gate bipolar transistors. This device includes spaced-apart, surface-adjoining, laterally-oriented anode and cathode regions. A channel region partially surrounds the cathode region, and a gate region is provided adjacent to, but insulated from, both the cathode and channel regions. The gate region extends vertically to induce a conduction channel during operation. These devices are fabricated in an epitaxial surface layer, offering advantages such as low on-resistance, fast switching speed, high breakdown voltage, and high latch-up current density.
