Title: Innovations of Yi-Chen Li
Introduction
Yi-Chen Li is a notable inventor based in Taichung, Taiwan. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is focused on electrostatic field strength measurement. This apparatus includes a laser generation device that emits a laser signal to a semiconductor fabrication component. It also features a reflection detection device that receives a reflection signal comprising light from the laser signal, which is reflected by the surface of the semiconductor fabrication component. The reflection detection device is equipped with an optical filter that blocks light outside a defined range of wavelengths, allowing only filtered light within that range to pass through. This filtered light is then used by a light sensor to generate an electrical signal, which the computer uses to determine measures of electrostatic field strength at the surface of the semiconductor fabrication component.
Another significant patent by Yi-Chen Li is the structure of a high electron mobility light emitting transistor (HEMT). This structure comprises a substrate, a HEMT region, and a gallium nitride LED (GaN-LED) region, all disposed on the substrate. A two-dimensional electron gas layer is present in both the HEMT and LED regions, with the HEMT region coupled to the LED region through this layer.
