1. Apparatus for drying the backside of a semiconductor wafer comprising:
a spin mechanism for spin coating a semiconductor wafer, the spin mechanism having a wafer chuck for securing the wafer; and
one or more gas ports adapted to deliver one or more pressurized gas jets to the backside of a semiconductor wafer secured to the spin chuck for evaporatively drying the backside of the semiconductor wafer.
