Signification wafer
Webmodel of a 6" diameter Si wafer with a 5.4" diameter Al film on it. The hatched portion represents the Al film. The wafer is perfectly circular except for a flat of 2.6" at the top. The initial thickness of the wafer is 25 mils where as the Al film layer is only 5 um thick. The wafer is finally back-ground to a thickness of 6 mils. Webwafer in American English.
