Title: Takeshi Kojima: Innovator in Semiconductor Technology
Introduction
Takeshi Kojima is a prominent inventor based in Kashiwa, Japan. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approach to controlling crystal film thickness and enhancing semiconductor device performance.
Latest Patents
One of Kojima's latest patents is a method for controlling the thickness of a thin crystal film. This method involves generating an electron beam in a vacuum atmosphere and directing it to a growing crystal to obtain a diffraction pattern. By detecting variations in the intensity of this pattern, Kojima's method allows for precise control over the crystal growth process. The technique can measure the thickness of the thin crystal film with an accuracy higher than 1000 Å in terms of the mono-layer.
Another notable patent is for a semiconductor device that features a superlattice semiconductor portion. This device comprises multiple pairs of superlattice semiconductor thin films, which are designed to create step differences in band edge energy. The structure of these thin films is monotonically changed during lamination, allowing for improved negative resistance characteristics and greater design flexibility in semiconductor applications.
