Title: Yukiko Uehara: Innovations in Semiconductor Technology
Introduction
Yukiko Uehara is a prominent inventor based in Kanagawa, Japan, known for his significant contributions to the field of semiconductor technology. With an impressive record of 19 patents, Uehara has made remarkable advancements, particularly in the design and manufacturing processes of transistors.
Latest Patents
Uehara's latest patent involves a semiconductor device that includes transistors with silicided impurity regions. This invention features a thin-film transistor (TFT) formed on an insulating substrate, which includes source, drain, and channel regions, along with a gate insulating film located above the channel region and a gate electrode on the insulating film. A notable aspect of this design is the inclusion of a high resistivity region placed between the channel region and the drain region, which effectively reduces the Ioff current. The method for creating this structure entails anodizing the gate electrode to develop a porous anodic oxide film. This film is then used as a mask for partially removing the gate insulating film, extending it beyond the gate electrode without entirely covering the source and drain regions. Following this, an ion doping of a conductivity element is administered, defining the high resistivity region beneath the gate insulating film.
