With a total of 9 patents to his name, he has made remarkable advancements in deposition methods that enhance the performance and reliability of electronic devices.
Latest Patents
One of his latest patents focuses on molybdenum deposition. This innovation provides methods for filling patterned features with molybdenum (Mo). The techniques involve selective deposition of Mo films on bottom metal-containing surfaces of a feature, which includes dielectric sidewalls. The selective growth of Mo on the bottom surface allows for bottom-up growth and ensures high quality, void-free fill. Additionally, he has developed related apparatus to support this process. Another notable patent involves depositing ruthenium layers in interconnect metallization. In this case, the deposition processes for ruthenium (Ru) feature fill include the application of a thin, protective Ru film under reducing conditions, followed by a Ru fill step under oxidizing conditions. The presence of protective Ru films formed under oxygen-free conditions can enable Ru fill without oxidation of an underlying adhesion layer or metal feature.
