ABSTRACT:
A wafer transfer system is operable with a front or side loading wafer carrier to move one or more wafers in a straight line from the carrier to a position in which the wafers are accessible for further processing by movement along the same straight line. The transfer system provides a wafer extractor which employs a plurality of paired fingers of a size and configuration to fit between the spaced, stacked wafers in the carrier. After insertion between the wafers, the fingers are movable by a small amount vertically to lift the wafers off the shoulders of the carrier. The fingers, now supporting the wafers, are movable generally horizontally along a straight line to remove the wafers from the carrier. The fingers are supported from a support structure in a manner which provides clearance for the wafers to pass through the support structure for further processing along the same straight line path.
