    摘要： A method for making substrates is disclosed. The method comprises providing a rod, which is made out of a substrate material and has an outside diameter substantially the same size as the outside diameter of a finished substrate and an inside diameter substantially the same size as the inside diameter of the finished substrate. The rod is cut with a multi-wire cutter to make a substrate slice substantially the same size as a finished substrate. The multi-wire cutter has wires positioned to substantially match the final thickness of the finished substrate. Additionally the cutting process is facilitated by using slurry and by providing a rocking motion between the rod and the wires of the multi-wire cutter so that the wires contact the rod in a rocking motion with respect to a normal to the center of the rod.
