Title: The Innovations of Ching-Nan Yang
Introduction
Ching-Nan Yang is a prominent inventor based in Hsinchu Hsien, Taiwan. He has made significant contributions to the field of semiconductor technology, holding a total of nine patents. His work focuses on advanced methods for forming thin film transistors and innovative devices in SRAM technology.
Latest Patents
One of his latest patents is a method of forming a novel self-aligned offset thin film transistor. This method involves patterning a first polysilicon layer on a substrate, defining a first dielectric with a via hole, and forming a second polysilicon layer. The process includes etching to create a residual portion of the layer and patterning undoped polysilicon on the first dielectric layer. An oxide layer is then formed to act as the gate oxide of the TFT, followed by further etching to define a second via hole. The method concludes with ion implantation to dope conductive species into the polysilicon layer, forming the source or drain regions.
Another significant patent is for a vertical poly load device in 4T SRAM technology. This vertical device is constructed on a buried contact and features a hollow in a planarized dielectric layer. The poly load is connected to the drain of the driver transistor and reduces standby current by increasing resistance as the voltage of the buried contact decreases.
