Abstract (en)

[origin: WO2018001793A1] The invention relates to a method for resuming an interrupted process for sawing a workpiece (6) into a plurality of wafers using a wire saw which uses a sawing wire (3), for example a diamond sawing wire, coated with a cutting grain. The method according to the invention is presented here as an example of a process for sawing a workpiece made of a semiconductor material into a plurality of wafers using a diamond wire saw but is also suitable for workpieces made of other materials. The invention additionally relates to a device for sawing a workpiece into a plurality of wafers using a sawing wire, said device allowing the detection of the position of a wire break.
