Abstract
A semiconductor processing robot is provided with a robot arm on which is mounted an integrated edge gripper having an orienting assembly and a detecting assembly. The orienting assembly operates to rotate a substrate such that a substrate reference marking, or indicium, is positioned at the detecting assembly. The detecting assembly detects the location of the reference indicium and thereby derives information about the relative orientation of the substrate in the integrated edge gripper.
