Latest Patents

Hirai's latest patents include a semiconductor device and a method of manufacturing the same, which involves a thin film containing a low concentration of hydrogen. In this innovative fabrication process for a semiconductor device used in TFT liquid crystal display systems, dehydrogenation annealing is performed before crystallizing amorphous silicon (a-Si). This step is crucial as it reduces the density of hydrogen in the p-Si film to 5×10 atoms/cm at most, preventing potential crystallization issues caused by excessive hydrogen. The process enhances the electrical characteristics of the semiconductor device by efficiently terminating dangling bonds in the p-Si film.

Another notable patent is for a display apparatus featuring an electric shielding wire and a method for its manufacturing. This electric shielding wire, made of chromium, is strategically placed near the edge of a substrate, serving as a lower electric layer for a TFT element. By implementing countermeasures against static electricity early in the manufacturing process, the elements on the substrate are safeguarded from damage due to static electricity generated in subsequent stages.
