Title: Shouji Miyahara: Innovator in Semiconductor Technology
Introduction
Shouji Miyahara is a prominent inventor based in Gunma, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 5 patents. His work focuses on improving the efficiency and reliability of semiconductor devices.
Latest Patents
Miyahara's latest patents include an insulated gate-type semiconductor device and a method for manufacturing semiconductor devices. The insulated gate-type semiconductor device features an interlayer dielectric film that is completely buried in a trench, preventing failures caused by step coverage. This innovation allows for a source electrode to be formed uniformly on the upper portion of a gate electrode. Additionally, the manufacturing method simplifies the process by requiring only one mask, thereby reducing device size and accounting for placement errors.
In his method for manufacturing semiconductor devices, particularly in MOSFETs, he addresses the issue of lowered threshold voltage due to the occlusion characteristics of the barrier metal layer. By providing an opening in the barrier metal layer and performing hydrogen annealing after forming the wiring layer, he enhances the amount of hydrogen that reaches the substrate. This innovation suppresses the lowering of the threshold voltage and reduces on-resistance by lowering impurity concentration in the channel layer.
