Abstract
Systems and methods for controlling the surface profiles of wafers sliced in a wire saw machine. The systems and methods are generally operable to alter the nanotopology of wafers sliced from an ingot by controlling the shape of the wafers. The shape of the wafers is altered for example by changing the temperature of a temperature-controlling fluid circulated in fluid communication with side walls attached to a fixed bearing sidewall of the wire saw.
