Abstract: A patterning method is described that utilizes self-assembled monolayers (SAMs) formed with hydroxamic acid compounds and area selective atomic layer deposition (ALD). In the examples, regions of the SAM exposed to extreme ultraviolet radiation (EUV) become resistant to ALD deposition. Subsequent treatment of the exposed SAM to an ALD process results in selective growth of an ALD film on the non-exposed regions of the SAM, leaving the exposed regions substantially free of ALD material.
