In these samples, the hard mask, Al<sub>2</sub>O<sub>3</sub>, was coated in the 150 mm Si wafers using the atomic layer deposition tool (ALD Picosun R200), presented in Figure S. 4. These sets of samples also had the lithography process done in the DUV stepper (Canon FPA-3000 EX4) to deposit 65 nm of BARC and 750 nm of DUV resist. Three different patterns were created after the development:
In these samples, the hard mask, Al<sub>2</sub>O<sub>3</sub>, was coated in the 150 mm Si wafers using the ALD 1 tool. These sets of samples also had the lithography process done in the DUV stepper to deposit 65 nm of BARC and 750 nm of DUV resist. Three different patterns were created after the development:


# Pillars of 1 µm with 1 µm pitch (50 nm Al2O3 + 65 nm BARC + 750 nm DUV).
