Abstract:
1. Apparatus for moving a substrate, comprising: a substrate holder for holding a substrate; a programmable robot programmed for moving both the substrate holder and a substrate held by the holder along X, Y and Z-axes, the X and Y-axes being generally horizontal and the Z-axis being generally vertical, said substrate holder comprising: a frame having an upper rim, an inner periphery defining a first opening for receiving a substrate, and a shoulder projecting laterally inward from the inner periphery for supporting the substrate in the first opening, said shoulder having an inner periphery defining a second opening smaller than the first opening for receiving a substrate support whereby the robot may transport the holder and a substrate therein to a position above the substrate support and then lower the holder to a position in which the shoulder is positioned below a top surface of the substrate support and the substrate is deposited on the top surface of the substrate support; and feet extending below the frame positioned for contact with the frame of a second substrate holder whereby two or more substrate holders can be stacked one above the other with a gap between the frames of adjacent holders.
