Title: Edward J Leonard: Innovator in Cleaning Technology
Introduction
Edward J Leonard is a notable inventor based in Fishkill, NY (US). He has made significant contributions to the field of cleaning technology, particularly in the semiconductor industry. With a total of 4 patents to his name, Leonard has developed innovative solutions that enhance the efficiency of chemical processing.
Latest Patents
One of Leonard's latest inventions is the Vapor Rinse-Vapor Dry Processing Tool. This cleaning apparatus is designed for cleaning chemically processed articles between chemical processing steps. The tool features a sealable pressurization vessel where articles, such as semiconductor wafers, are placed after a chemical process step. The vessel is sealed, and the pressure is adjusted. Solvent within the vessel is heated to a boil, creating vapor. This vapor is then recondensed by a primary condensing coil, allowing the condensed solvent to rain onto the article for effective washing. Once the article is clean, it is dried as a secondary condensing coil condenses the solvent vapor, causing the distilled solvent to rain into a collection tray. The collected solvent is channeled into a sealed storage reservoir after all solvent is gathered, and the vessel is opened to remove the cleaned article.
