Patent ID: 8778083

Claim:
A lateral-flow deposition apparatus in which a process gas flows between a first surface of a reaction chamber where a substrate is disposed and a second surface of the reaction chamber facing the first surface, the process gas flowing in a direction that is substantially in parallel with the substrate, the apparatus comprising: a substrate support that moves up/down and rotates the substrate while supporting the substrate; a substrate support heater disposed under the substrate support, transferring heat to the substrate support, and moving up/down, wherein the substrate support heater and the substrate support are spaced at a distance from each other; a reactor cover that defines the reaction chamber by contacting the substrate support heater; a substrate support lifter and a substrate support rotator that move the substrate support; and a sub-gas inlet allowing a sub-gas to be injected between the substrate support and the substrate support heater, wherein the sub-gas inlet is disposed at a center portion of the substrate support heater.
