Abstract
A semiconductor wafer transfer machine for transferring first wafers having a first diameter from a first transferor carrier to a first receiver carrier and second wafers having a second diameter different from the first diameter from a second transferor carrier to a second receiver carrier. The wafer transfer machine includes a base plate with a longitudinal axis for placement on the base plate of the transferor carriers and the receiver carriers and a mechanism for transferring wafers contained in the first and second transferor carriers to the first and second receiver carriers, respectively. The wafer transfer machine also includes an adjustable positioner that comprises (1) a transferor positioning mechanism for aligning the first and second transferor carriers on the top surface of the base plate, (2) a first receiver positioning mechanism for aligning the first receiver carrier in a first position with respect to the first transferor carrier on the top surface of the base plate, and (3) a second receiver positioning mechanism for aligning the second receiver carrier in a second position with respect to the second transferor carrier on the top surface of the base plate.
