Method of slicing artificial single crystal corundum ingot

摘要

The present invention as it cut the artificial corundum single crystal ingot of R-axis direction, the present invention relates to an ingot cutting method that can reduce the cutting time and consumption of the wire. Ingot cutting method according to the invention if the bottom of the R Of the ingot (ingot) of cylindrical shape in a way that cutting (slicing) a wafer form, the ingot , , And It is cut in the direction other than the direction parallel to the direction. In particular, the ingot side of the bottom direction of the ingot But with the cutting in a direction perpendicular, Direction that forms an angle of the direction and the range 30 ° to 60 °, 120 ° to of the direction that forms an angle of the direction, direction, and range 300 ° to 330 ° forms an angle in the range of 210 ° to 240 ° forms an angle of 150 ° range When cut in any direction parallel to the one direction, it can easily be cut more. ;
