Abstract: A vapor deposition device includes a reactor including a reaction chamber and an injector for injecting vapor into the reaction chamber. The device also includes a manifold for delivering vapor to the injector. The manifold includes a manifold body having an internal bore, a first distribution channel disposed within the body in a plane intersecting the longitudinal axis of the bore, and a plurality of supply channels disposed within the body and in flow communication with the first distribution channel and with the bore.
