Title: The Innovations of Mitsuhiro Ogawa
Introduction
Mitsuhiro Ogawa, an esteemed inventor from Yao, Japan, has made significant contributions to the field of cleaning technologies. With a total of two patents to his name, Ogawa has focused on developing advanced methods and apparatuses for cleaning applications, particularly in the semiconductor industry.
Latest Patents
Mitsuhiro Ogawa's latest patents include a "Two-Fluid Cleaning Jet Nozzle and Cleaning Apparatus, and Method" and an "Apparatus and Method for Cleaning Semiconductor Wafers."
The two-fluid cleaning jet nozzle features an atomizing unit with an atomizing tube that utilizes pressurized gas to atomize liquid into droplets. An accelerating unit then jets these droplets against a workpiece, efficiently removing dust particles. Notably, the sectional area of the atomizing tube for gas flow is larger than that of the accelerating tube for liquid droplets and gas, and the design includes options like a straight cylindrical tube or a Laval nozzle.
The apparatus and method for cleaning semiconductor wafers improve the cleaning process by incorporating an exhaust chamber with a sub-outlet, which slows down the flow of frozen micro-particles to prevent them from rebounding towards the wafer. As a result, cleaned wafers maintain higher cleanliness standards.
