Abstract:
1. An atomic layer deposition (ALD) reactor, comprising: a reaction chamber comprising a reaction space, a reactor cover and a reactor base in sealing contact with the reactor cover to define the reaction space, the reactor base being detachable from the reactor cover; a reactor base driver configured to vertically move the reactor cover between first and second positions, wherein the reactor space is open at the first position, and is closed at the second position, wherein the reactor base driver is configured to independently adjust at least three portions of the reactor base to provide a substantially perfect seal to the reactor space at the second position, the at least three portions being horizontally spaced apart from one another and are not aligned with one another; one or more inlets; an exhaust outlet; a gas flow control guide structure residing over the reaction space, the gas flow control guide structure being interposed between the one or more inlets and the reaction space, the gas flow control guide structure comprising one or more gas channels, each of the channels extending from a respective one of the one or more inlets to a first portion of a periphery of the reaction space, at least one of the channels including two sidewalls that define the channel so as to widen as the channel extends from the inlet to the reaction space, a substrate holder positioned to expose a supported substrate to the reaction space, wherein the gas flow control guide structure is configured to generate a gas flow direction of reactant in the reaction space that is predominantly parallel to a major surface of the supported substrate from the first portion of the periphery of the reaction space to a second portion of the periphery of the reaction space, wherein the second portion is on the opposite side from the first portion.
