Abstract
A substrate processing apparatus having a supply of substrates, a substrate transport module, and a substrate processing module. The transport module has a movable arm assembly and two substrate holders mounted to the movable arm assembly. The substrate holders each have two separate holding areas for simultaneously holding two substrates. The movable arm assembly has two pairs of driven arms. Each pair of driven arms is connected to a separate one of the holders for extending and retracting the holders along a radial path relative to a center of the movable arm assembly.
