Slicing method |
摘要 |
The present invention provides a slicing method comprising winding a wire around a plurality of grooved rollers and pressing the wire against an ingot to be sliced into wafers while supplying a slurry for slicing to the grooved rollers and causing the wire to travel, wherein a supply temperature of the slurry for slicing is controlled, and slicing is performed in such a manner that the supply temperature of the slurry for slicing and a temperature of the ingot become at least 30°C or above at end of slicing the ingot. As a result, there is provided the slicing method that can alleviate precipitous cooling of an ingot in the time close to end of slicing the ingot and thereby suppress production of a nano-topography when slicing the ingot by using a wire saw. |
