摘要:
An actuated edge grip chuck includes tabs with raised portions that press against the side of a substrate as opposed clamping on the top or bottom surfaces. The edge grip chuck includes a solid-state actuator to move a moveable tab into an open position. The solid-state actuator may be, e.g., a piezoelectric actuator or a shape memory alloy. The tab may be biased into the closed position such that when a substrate is held by the edge by the moveable tab and one or more fixed tabs. If desired, more than one moveable tab may be used.
