Design of an atomic layer deposition reactor for hydrogen .

a precursor has been documented, to our knowledge there are no reports on the safe design of these systems. In this article, we describe a carefully designed viscous-flow ALD reactor which is comprised of fully H 2S compat-ible components, contains a purging system for removing residual H 2S before venting, and contains an automatic


The second precursor (precursor 2) is pulsed into the reactor and reacts with the precursor 1 already present at the surface of the sample. The reaction generates the desired monolayer and a byproduct. The byproduct and the excess of precursor are then purged from the reactor with inert gas (N 2) (step 4).
