Latest Patents

Ho-wook Choi holds a patent titled "Method of forming fine pitch hardmask patterns and method of forming fine patterns of semiconductor device using the same." This patent describes a method that includes forming a hardmask layer on a substrate and creating a plurality of first mask patterns on the hardmask layer. A buffer layer is then formed on these first mask patterns, which defines recesses between adjacent patterns. The process continues with the formation of second mask patterns within these recesses. The buffer layer is partially removed to expose the upper surfaces of the first mask patterns, and subsequently, the hardmask layer is etched to create hardmask patterns. This innovative approach enhances the precision and efficiency of semiconductor device fabrication.
