Title: Yong-Nam Choi: Innovator in Functional Water Supply Systems
Introduction
Yong-Nam Choi is a notable inventor based in Chonan-shi, South Korea. He has made significant contributions to the field of functional water supply systems, holding 2 patents that showcase his innovative approach to technology.
Latest Patents
One of his latest patents is a "System and method for supplying functional water." This invention provides a supply system designed to deliver functional water to a process unit that treats a substrate using this specialized water. The system includes a functional water generator that supplies the water through a dedicated pipe to a distributor. During the processing, the functional water is supplied to the process unit, and when the process is not active, it is returned to the generator via a returning pipe. A buffer tank is integrated into the supply pipe, allowing for the measurement of the functional water's concentration. If the concentration deviates from a predetermined range, the water is redirected back to the generator.
Another significant patent is the "Apparatus for treating substrate." This invention focuses on an apparatus designed for etching the top edge and bottom of a wafer. It features a substrate support part that holds the wafer and a movable protective part that prevents etching fluid from contaminating non-etch areas of the wafer. The etching process employs both wet and dry methods to achieve precise results.
