ABSTRACT:
A handler attachment device used for loading and unloading of wafer cassettes into and out of a spray processing tool is comprised of a rectangularly-shaped main body member, two U-shaped gripping members, and two L-shaped bracket members all interconnected together. The main body member includes a narrow middle section and opposed first and second end sections having angled mounting areas disposed therein. The two U-shaped gripping members are mounted to the corresponding first and second mounting areas on the body member. The two L-shaped bracket members are mounted to opposed side edges of the body member for engaging with the wafer cassette. The U-shaped gripping members are grasped by the corresponding hands of an operator in a manner so as to reduce and minimize fatigue and stress to his hands, wrists and arms.
