Title: **Innovative Contributions of Yuh-Jia (Jim) Su**
Introduction
Yuh-Jia (Jim) Su, based in Cupertino, CA, is an accomplished inventor with a remarkable portfolio of 20 patents. His work primarily focuses on enhancing processes in semiconductor manufacturing, particularly in cleaning methodologies post-etching.
Latest Patents
One of Su's latest inventions is a method for post-etch cleans, which presents a cleaning process that increases efficiency while minimizing damage to device structures. The process entails a sequence of cleaning steps: after etching and photoresist stripping, a first plasma clean is performed, which may involve multiple steps. This is followed by a first hydrogen-oxygen (HO) based clean, which can take forms such as a de-ionized water rinse, water vapor clean, or a plasma clean that includes hydrogen and oxygen. A second plasma clean follows, again consisting of various steps, before concluding with a second HO based clean. This innovative approach allows for effective cleaning of diverse etches, including metal etches, via etches, contact etches, polysilicon etches, nitride etches, and shallow trench isolation etches. Additionally, the removal of photoresist can be executed before, during, or after these cleaning processes using an oxygen-containing plasma at low temperatures.
