摘要: A plasma reactor of the single wafer, planar electrode type achieves improved serviceability by means of a service seal arrangement. The lower electrode of the plasma reactor is carried on a chuck. Both the chuck and the upper portions of the reactor seal to an upper plate of a vacuum containment vessel. A wafer transport mechanism is contained within the vacuum containment vessel. The sealing arrangement allows removal of the upper portions of the reactor and even replacement of the lower electrode without disturbing the vacuum in the vacuum containment vessel.

摘要: In apparatus for transporting semiconductor wafers, a spatula contains a single major recess for receiving a wafer. Adjacent one edge of the recess is a shoulder for locating the wafer in the sequence of operations for loading the spatula. As a result of the sequence, the center of the wafer is held at a predetermined, known location.
