Zusammenfassung:The present invention generally includes a shadow frame with alignment inserts that may permit the shadow frame to be properly aligned on the susceptor. The shadow frame may have one or more alignment inserts. The alignment inserts may be coupled to a cavity formed in the bottom surface of the shadow frame. The alignment inserts may be shaped to receive an alignment button that may be present on the susceptor. Thus, as the susceptor raises to the processing position and retrieves the shadow frame, the shadow frame may align properly on the susceptor.
