WebS passivation of a HfO 2 film on an InP substrate is demonstrated using annealing in H 2 S ambient either before or after ALD of the HfO 2 film. We examined the resulting distribution and chemical state of the incorporated S both in the HfO 2 film and at its interface with the InP substrate using secondary ion mass spectroscopy and X-ray absorption spectroscopy.
