Abstract
A method of backgrinding wafers wherein backgrinding tape or a pad is applied to the chuck and not to the wafers. The backgrinding tape or pad is left on the chuck as each wafer is sequentially placed on the tape or pad, background, rinsed on the backside, removed from the tape and then cleaned on the front side and backside. A tool for applying tape to a chuck, as described herein, facilitates this method.
