    摘要: A method for processing a semiconductor wafer to reduce surface roughness. The wafer has two flat, opposite faces with a peripheral edge extending around a circumference of the wafer between the faces. The method includes, in the following order, the steps of burnishing the edge, and etching the edge. The step of burnishing is defined by a relative rubbing motion between the edge and an abrasive appliance to remove damage from the edge, the rubbing motion occurring free from any polishing solution or chemical slurry. The step of etching includes exposing the wafer to a liquid chemical etchant for a period of time to remove additional damage from the edge. The method may also include, before the other steps, a step of lapping at least one face of the wafer to remove semiconductor matter through a relative rubbing motion between the face and an abrasive lapping plate in the presence of an abrasive liquid slurry.

    摘要: An apparatus and process for chemical-mechanical polishing an edge of a semiconductor wafer using a heated polishing pad and a heated liquid chemical slurry. The apparatus includes a rotatable drum having a cylindric outer surface, a heatable mat positioned around the outer surface of the drum, and a polishing pad in generally parallel arrangement with the mat. A wafer holder, a container of liquid slurry, and a slurry delivery system are also included. The process includes the steps of heating a liquid slurry to an elevated temperature and applying heat to the polishing pad from an underside of the polishing pad to elevate the temperature of the polishing pad. A peripheral edge of a semiconductor wafer is engaged against a polishing side of the polishing pad, and a relative motion is effected between the wafer and the pad while simultaneously dispensing the heated slurry onto a region where the edge of the wafer engages the pad.
