Title: Chieh-Jen Ku: Innovator in Thin Film Transistor Technology
Introduction
Chieh-Jen Ku is a prominent inventor based in Edison, NJ (US). He has made significant contributions to the field of thin film transistors, holding a total of 5 patents. His work focuses on advanced materials and technologies that enhance the performance and efficiency of electronic devices.
Latest Patents
One of his latest innovations is the Magnesium zinc oxide-based high voltage thin film transistor. This device is built on a transparent substrate, such as glass, and features a circular drain along with a ring-shaped source and gate. These design elements help reduce non-uniformity in the electric field distribution. Controlled magnesium doping in the channel, along with modulated magnesium doping in a transition layer at the channel-gate dielectric interface, improves the device's operating stability and increases its blocking voltage capability to over 600V. The MZO HVTFT is particularly useful for fabricating micro-inverters in photovoltaic systems on glass and for self-powered smart glass applications.
Another notable patent involves a ZnO-based system on glass for advanced displays. This innovation includes a display pixel structure that features system-on-glass (SOG) substrates with embedded non-volatile resistive random access memory (iNV-RRAM). The pixels designed with this technology offer high frame rates and low power consumption. The entire SOG is based on ZnO devices, and various components such as TFT, TCO, RRAM, inverters, and shift registers are achieved through the doping of different elements into selected ZnO active regions. This approach significantly reduces the cost of packaging control circuitry onto a display system's backplane, resulting in a low-cost, lightweight, and ultra-thin display.
