发明名称 Apparatus for separating wafers from polishing pads used in chemical-mechanical planarization of semiconductor wafers
摘要 The present invention is a planarizing machine for use in chemical-mechanical planarization of semiconductor wafers that has a moveable platen, a polishing pad, a wafer carrier, and a wafer separator. The polishing pad is positioned on the platen, and it has a planarizing surface with an operational zone upon which the wafer may be planarized. The wafer carrier holds a wafer and is positionable opposite the polishing pad to engage the wafer with the operational zone of the polishing pad. The wafer separator engages either the polishing pad, the wafer, or the wafer carrier to urge a portion of the wafer away from the pad.
