Abstract
A method for processing a semiconductor wafer is provided. The method includes transferring the semiconductor wafer above a wafer placement device having a plate to align an edge of the semiconductor wafer with a first buffer member positioned in a peripheral region of the plate and to align a center of the semiconductor wafer with a second buffer member positioned in a central region of the plate. Each of the first buffer member and the second buffer member has a stiffness that is less than that of the plate. The method further includes lowering down the semiconductor wafer to place the semiconductor wafer over the plate.
