Abstract
A processing system includes a robot arm with an end effector having a longitudinal axis, the robot arm having a reach of at least 45 inches, wherein the end effector includes: a first wafer pocket defined within the end effector at a first location along the longitudinal axis, wherein the first wafer pocket has the reach of at least 45 inches; and a second wafer pocket defined within the end effector at a second location along the longitudinal axis, wherein the second wafer pocket has a second reach that is less than 45 inches. The end effector is capable of concurrently carrying a first wafer in the first wafer pocket and a second wafer in the second wafer pocket.
