THIN SUBSTRATE, MASS-TRANSFER BERNOULLI END-EFFECTOR
摘要:
An end effector (20, 20′) for simultaneously transferring a batch of substrates (202). The end effector (20, 20′) includes a set of juxtaposed substrate grippers (22, 22′) having a pitch between pairs of grippers (22, 22″) that does not exceed six (6.00) mm. Each gripper (22, 22′) has a contact surface (54, 54′) against which a substrate (202) becomes clamped upon injecting a gaseous jet into an open groove (56A, 56B, 56′) formed into the contact surface (54, 54′). Due to the close spacing between immediately adjacent pairs of substrate grippers (22, 22′), the open groove (56A, 56B, 56′) must be very shallow. The open groove (56A, 56B, 56′) can be characterized by having a groove depth into the contact surface (54, 54′) that is between two (2 .00) mm and two and four tenths (2.40) mm. Alternatively, the open groove (56A, 56B, 56′) can be characterized by having a groove width at the contact surface (54, 54′) that is at least three (3) times larger than a groove depth into the contact surface of the substrate gripper.
