Deposition system with modular deposition heads

Abstract:

A deposition unit for a thin film deposition system includes one or more of deposition heads and a gas manifold. Each deposition head includes an output face having a plurality of gas openings, a mounting face including a plurality of deposition head gas ports, and connecting gas passages. The gas manifold includes an attachment face having one or more interface regions, each interface region including a plurality of manifold gas ports in positions corresponding to the deposition head gas ports. Each deposition head is fastened to the gas manifold in an interface region with sealing elements positioned between the manifold gas ports and the deposition head gas ports. The mounting face of each deposition head and the attachment face of the gas manifold include alignment features for aligning each deposition head with the interface region of the gas manifold.
