Abstract:
A method of forming a polishing pad having a smaller diameter than an object to be planarized and to be used for planarizing the object by chemical-mechanical planarization, the method comprising:placing a polishing surface of the polishing pad in contact with an abrasive surface of a conditioning object having a shape identical to the object to be planarized; engaging the polishing surface of the polishing pad with the abrasive surface of the conditioning object under conditions substantially equal to the conditions to be applied for planarizing the object; observing the polishing surface; and disengaging the polishing surface of the polishing pad from the abrasive surface of the conditioning object when abrasion of a center region of the polishing surface of the polishing pad by the abrasive surface of the conditioning object is initially detected.
