Title: Shinichi Yagihashi: Innovator in Polycrystalline Silicon Wafer Fabrication
Introduction
Shinichi Yagihashi is a notable inventor based in Sapporo, Japan. He has made significant contributions to the field of semiconductor manufacturing, particularly in the fabrication of polycrystalline silicon wafers. With two patents to his name, Yagihashi's work has advanced the technology used in the production of high-quality silicon wafers.
Latest Patents
Yagihashi's latest patents include a method for fabricating polycrystalline silicon wafers. This method involves radially outwardly flowing molten liquid of silicon base material on the wafer forming surface of a turntable mechanism using centrifugal force. This process creates a thin molten liquid layer in a controlled atmosphere, which is then cooled and solidified. An apparatus designed for this method includes a recovery tray to collect excessive silicon liquid and a wafer tray positioned on top of it. The wafer forming surface is cooled with a coolant, allowing large crystalline grains to grow freely, enhancing the quality of the wafers produced.
Another patent by Yagihashi details an apparatus for fabricating polycrystalline silicon wafers, which similarly utilizes centrifugal force to achieve the desired results. This innovative approach allows for the growth of large crystalline grains in a manner that improves upon conventional methods.
