Abstract
The wafer alignment fixture is provided with a cassette support which can be slid between two positions on a base plate. In one position, the cassette support is aligned with a roller in order to align notched wafers with each other. In the second position, the cassette support is aligned with a second roller so as to effect alignment of wafers having flats.
