摘要 |
An apparatus for aligning semiconductor wafers includes equipment for positioning a first surface of a first semiconductor wafer directly opposite to a first surface of a second semiconductor wafer and equipment for aligning a first structure on the first semiconductor wafer with a second structure on the first surface of the second semiconductor wafer. The aligning equipment comprises at least one movable alignment device configured to be moved during alignment and to be inserted between the first surface of the first semiconductor wafer and the first surface of the second semiconductor wafer. The positioning equipment are vibrationally and mechanically isolated from the alignment device motion.
