Title: Tadayuki Asaishi: Innovator in Semiconductor Technology

Introduction

Tadayuki Asaishi is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approach to improving semiconductor devices.

Latest Patents

His latest patents focus on a semiconductor device that features an impurity diffusion surface layer formed in a silicon substrate. An aluminum electrode is arranged in direct contact with this impurity diffusion layer. The surface layer contains germanium (Ge) as an impurity, which serves to change the lattice constant at a concentration of at least 1.times.10.sup.21 cm.sup.-3 under a thermal non-equilibrium state. This adjustment allows for a decrease in the Schottky barrier height at the contact between the surface layer and the electrode. Additionally, the surface layer incorporates electrically active boron as an impurity, which imparts carriers at a concentration higher than the critical concentration of solid solution in silicon under thermal equilibrium. The presence of Ge enhances carrier mobility within the surface layer compared to that within silicon.
