Patent number: 11854806Abstract: Devices are made by self-aligned quad pitch patterning (SAQP) and methods for making devices by self-aligned quad pitch patterning (SAQP) use a single spacer in the process. An intermediate process step called self-aligned double patterning (SADP) is used to double the pitch following the spacer deposition. A pattern is formed on a substrate, the pattern having ultra-fine resolutions by repeating the SADP step twice for pitch quadrupling and introducing a reversal layer to form a fine trench pattern and hole pattern. An initial pattern is obtained by the X-Y double line exposures. Reverse material is applied on the initial pattern and subsequent etching process converts each initial trench pattern to a line. The pattern designs or pattern layouts have improved LER/LWR (line edge roughness and line width roughness respectively) for below 12 nm lines and trenches in order to create self-aligned cross pitch quad trenches.Type: GrantFiled: May 20, 2021Date of Patent: December 26, 2023Assignee: Tokyo Electron LimitedInventors: Daniel Fulford, Anton J.
