Latest Patents
Among his latest inventions, one stands out: "Silicon and oxygen ion co-implanation for metallic gettering in epitaxial wafers." This novel method involves co-implanting silicon and oxygen into a substrate wafer, followed by low-temperature annealing. The unique process allows for the deposition of an epitaxial layer on the substrate's surface, functioning as an in-situ anneal. This leads to the formation of dislocation loops that serve as intrinsic gettering sites. The method further ensures that oxygen precipitate clusters anchor these dislocation loops, preventing them from gliding to the wafer surface over time, thus enhancing the overall performance of the wafers.
