Title: Innovations of Kuo-Chi Tsai
Introduction
Kuo-Chi Tsai is a prominent inventor based in Taoyuan, Taiwan. He has made significant contributions to the field of semiconductor technology, holding a total of 11 patents. His work focuses on developing advanced devices that enhance temperature sensing and semiconductor manufacturing processes.
Latest Patents
One of his latest patents is a temperature sensing device that includes a resistor string and control circuitry. This device features a variable resistor, a first resistor, and a second resistor arranged in series. The resistor string connects between a sensing end and a reference ground voltage. The first and second resistors are linked to a monitoring end to provide a monitoring voltage. The control circuitry compares this monitoring voltage with several reference voltages to generate sensing temperature information and adjustment information. The control circuitry then adjusts the resistance of the variable resistor based on this information. Notably, the first resistor is a polysilicon resistor, while the second is a silicon carbide diffusion resistor.
Another significant patent is a method of manufacturing a silicon carbide semiconductor power device. This method allows for the simultaneous formation of a power device in the high voltage region and a CMOS device in the low voltage region, thereby saving time and costs. The process begins with the formation of a first drift layer on a substrate, followed by the creation of a shielding region within this layer. A second drift layer is then added, along with a pick-up region that connects to the continuous region of the shielding region. This innovative approach minimizes the body effect while forming NMOS and PMOS devices alongside the power device.
