Abstract:
Embodiments described herein relate to an apparatus and method for securing and transferring substrates. A substrate carrier, having one or more electrostatic chucking electrodes disposed therein, electrostatically couples a substrate to the carrier. Optionally, a mask may also be electrostatically coupled to the carrier and may be disposed over a region of the carrier not occupied by the substrate. In one embodiment, multiple electrode assemblies are provided such that a first electrode assembly chucks the substrate to the carrier and a second electrode assembly chucks the mask to the carrier. In another embodiment, a pocket is formed in the carrier and an electrode assembly provides chucking capability within the pocket.
