His work focuses on advancing methods that enhance the precision and efficiency of semiconductor manufacturing processes.
Latest Patents
Among his latest patents is a system for concurrent or cyclical etch and directional deposition. This innovative etching and deposition system includes a process chamber with a platen for supporting a substrate. It features a reactive-ion etching (RIE) source that produces an ion beam directed into the process chamber for substrate etching. Additionally, it incorporates two plasma enhanced chemical vapor deposition (PECVD) sources, each adapted to produce radical beams for depositing different materials onto the substrate.
Another significant patent involves methods of modifying openings in hardmasks and photoresists to achieve desired critical dimensions. This method includes performing a pre-implant on the mask to implant it with a dopant material, which densifies the mask and enlarges the opening. The process also involves directing radical beams at both lateral sides of the opening to deposit layers of material, ensuring precise control over the dimensions.
