Title: Akio Ichimura: Innovator in Semiconductor Technology
Introduction
Akio Ichimura is a prominent inventor based in Ibaraki, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 6 patents. His work focuses on improving the performance and reliability of semiconductor devices.
Latest Patents
Ichimura's latest patents include innovative designs for semiconductor devices and methods of manufacturing them. One notable patent describes a semiconductor device that incorporates a super junction structure, where p-type and n-type columns are periodically arranged. This design allows for a shallower depth of the p-type column region in the cell region compared to the surrounding intermediate region. As a result, the breakdown voltage in the cell region is lower, enabling the avalanche breakdown phenomenon to occur preferentially in that area. This advancement helps to avoid local current constriction and enhances avalanche resistance.
Another significant patent outlines a method for manufacturing a semiconductor device with a high aspect ratio super junction structure. This process involves forming an epitaxial layer in layers using the trench fill method, where trenches are created in each layer as it is formed. This innovative approach contributes to the overall efficiency and effectiveness of semiconductor manufacturing.
