Patent number: 12248248Abstract: A method, apparatus, and system for processing a material stack. A hydrogen silsesquioxane layer is deposited on the material stack. A diffusion barrier layer is deposited on the hydrogen silsesquioxane layer to form a bilayer.

The electron beam applies the dose that is selected based on a pattern density of features for the material stack to have a desired level of exposure of the hydrogen silsesquioxane layer for the selected feature geometry. The hydrogen silsesquioxane layer is developed. The exposed portion remains on material stack.Type: GrantFiled: October 25, 2021Date of Patent: March 11, 2025Assignee: The Boeing CompanyInventors: Antonio Mei, Ivan Milosavljevic, Amanda Simpson
