Abstract
A robotic semiconductor handling system includes two robot arms for transferring substrates between processing, cooling, and storage stations. The first robot arm has a paddle-type end effector adapted such that it can support one substrate at a primary location as well as a second substrate at a secondary staging location. The second robot arm is a Bernoulli-style wand that transfers a substrate from the primary location to the secondary one, and transfers substrates from either location to the process chamber. The use of the dual-location paddle allows for a significant reduction in cycle-time over a single paddle location and a Bernoulli wand system.
