Abstract:
A wafer clamping mechanism, comprising:a base plate; a first cam rotatably coupled to said base plate about a first cam rotation point, where said first cam is configured to couple with a first robot arm; a second cam rotatably coupled with to said base plate about a second cam rotation point different to said first cam rotation point, where said second cam is configured to couple with a second robot arm; a first rotating clamp mechanism rotatably coupled to said base plate about a single fixed point, and configured to interact with said first cam to engage and disengage said first rotating clamp mechanism from contacting a wafer; and a second rotating clamp mechanism rotatably coupled to said base plate about a single fixed point, and configured to interact with said second cam to engage and disengage said second rotating clamp mechanism from abutting said wafer.
