Title: Kyoko Nakashima: Innovator in Semiconductor Technology
Introduction
Kyoko Nakashima is a prominent inventor based in Nagoya, Japan. She has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase her innovative approach to device manufacturing.
Latest Patents
One of her latest patents is a method of manufacturing a semiconductor device. This method involves forming a pn column designed to have a strip form in the substrate section. It features a repetitive pattern of p-conduction and n-conduction types on the substrate surface, allowing for the formation of multiple semiconductor devices with the same structure. The process includes forming residual constituent elements in areas where the repetitive patterns are located, with the pn column serving as part of each device's constituent element. The final step involves dicing the individual semiconductor devices into chips.
Another notable patent is related to a vertical type MOSFET device with a super junction structure. In this design, N conductive type and P conductive type column regions are alternately aligned. The patent addresses the distance between the terminal end of the active region and the terminal end of the column region. By positioning the terminal end of the column region at a specific distance from the active region, electric field concentration is prevented, thereby improving the breakdown voltage of the vertical type MOSFET.
