Abstract: In a deposition apparatus, as a plurality of plasma connection terminals that transfer plasma power to a plasma electrode are coupled in parallel to the plasma electrode, resistance caused by the plurality of plasma connection terminals is reduced and a current is distributed such that heat generated in the plurality of plasma connection terminals can be distributed. Therefore, even if high RF power is used, by preventing the plurality of plasma connection terminals from being oxidized, plasma is stably supplied and thus, stability of a deposition apparatus and the accuracy of a process can be enhanced.

Abstract: A thin film deposition apparatus including a substrate mounting error detector, a chamber and a substrate support positioned in the chamber. The substrate support is configured to support a substrate. The substrate mounting error detector includes: a light source configured to provide a light beam to the substrate, such that the substrate reflects the light beam; a collimator configured to selectively pass at least a portion of the light beam reflected by the substrate; and an optical sensor configured to detect the at least a portion of the reflected light beam passed by the collimator. The detector is positioned and oriented to detect substrate position on a lowered support prior to raising the support into contact with an upper cover of a clamshell reactor arrangement. This configuration allows a thin film deposition process only if the substrate is correctly mounted on the substrate support. Thus, abnormal deposition due to a substrate mounting error is prevented in advance.
