Title: The Innovations of Sadatoshi Takechi
Introduction
Sadatoshi Takechi is a prominent inventor based in Nara, Japan. He has made significant contributions to the field of thin-film transistors, holding a total of 14 patents. His work has advanced the technology used in electronic devices, making them more efficient and cost-effective.
Latest Patents
Among his latest patents is a method of manufacturing a thin-film transistor with reinforced drain. This invention details a thin-film transistor where the source and drain electrodes are film laminates consisting of at least two layers. The first layer film of the laminate is formed to a thickness of 10 to 700 angstroms and is in ohmic contact with the underlying semiconductor film. The second layer film, which has a thickness of more than about 2000 angstroms, is made from a material that maintains sufficient adhesion strength even when formed at lower temperatures. This innovation allows for the materials used for the source and drain electrodes to be formed into thin films using ordinary sputtering or vacuum deposition techniques, making them low in cost and readily available.
Another notable patent is a thin-film transistor that comprises a substrate with source and drain electrodes, a semiconductor layer, a gate electrode, and a gate insulating layer. This design features a portion of the drain electrode overlapping with the gate electrode while the source electrode is spaced apart, enhancing the functionality of the transistor.
