WebJan 1, 2016 · Ultrathin TaN and Ta1-xAlxNyfilms with x = 0.21 to 0.88 were deposited by atomic layer deposition (ALD) and evaluated for Cu diffusion barrier effectiveness compared to physical vapor deposition (PVD) grown TaN. WebSep 1, 2015 · Therefore, an etch stop layer (ESL) for nMOS is of great importance to protect the ALD TiN layer from the metal stripping. Tantalum nitride (TaN) or tantalum (Ta) is deemed as a potential candidate because they exhibit better resistance than TiN in various reagents as depicted by Hussain et al. [9].
