Claim:
1. A method of forming a semiconductor device, the method comprising: receiving a substrate; forming a termination layer on a top surface of the substrate, using one of a molecular beam epitaxy (MBE) process and a chemical vapor deposition (CVD) process, wherein the termination layer includes deuterium deposited within the substrate during the formation of the termination layer, such that a portion of a semiconductor of the substrate remains at the top surface of the substrate; after forming the termination layer and after deposition of the deuterium, using an atomic layer deposition (ALD) process to deposit a dielectric layer including HfO during the deposition of the dielectric layer, using the termination layer as a diffusion barrier to material deposited by the ALD process; wherein the forming of the termination layer produces the termination layer having multiple layers of deuterium atoms between the substrate and the dielectric layer.
