Abstract: In a method, a resist material is dispensed through a tube of a nozzle of a resist pump system on a wafer. The tube extends from a top to a bottom of the nozzle and has upper, lower, and middle segments. When not dispensing, the resist material is retracted from the lower and the middle segments, and maintained in the upper segment of the tube.
