Title: The Innovative Contributions of Sungjae Lee
Introduction
Sungjae Lee is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of silicon substrate analysis, holding a total of 4 patents. His work focuses on developing methods and apparatuses that enhance the accuracy and efficiency of substrate analysis.
Latest Patents
One of his latest patents is a method for analyzing silicon substrates. This invention provides a high-accuracy approach to detecting impurities, such as trace metals, in silicon substrates that are covered with thick nitride films. The method utilizes an advanced silicon substrate analysis apparatus, which includes components such as an analysis scan port, a substrate conveyance robot, an aligner, a drying chamber, a vapor phase decomposition chamber, an analysis stage, and a nozzle for substrate analysis. Additionally, it features an analysis liquid collection unit and an analyzer for performing inductive coupling plasma analysis.
Another notable patent is a substrate analysis method that employs a nozzle to discharge an analysis liquid from its tip. This method scans the substrate surface with the discharged liquid and subsequently sucks it back. The process involves positioning a liquid catch plate to retain the analysis liquid and ensuring that the substrate's end part contacts the retained liquid. The nozzle and liquid catch plate move concurrently around the substrate's periphery, allowing for effective analysis of the substrate's end part.
