This study introduces area‐selective atomic layer deposition (AS‐ALD) using fluorocarbon (FC) mask patterns with low surface energy. FC mask patterns were formed on a glass substrate by inkjet printing method. The surface energy of the printed FC thin film was 13.04 dyne/cm enough low to inhibit nucleation and growth during ALD. 10 µm wide Al 2 O 3 patterns were selectively formed by removal of FC mask patterns using oxygen plasma after Al 2 O 3 ALD processes.
