Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A system configured to separate a die in a silicon carbide (SiC) semiconductor wafer, comprising:
a cutting apparatus including:
a cutting tool configured to perform a cutting operation on a first surface of the SiC semiconductor wafer in a gap between die sections to produce a cut that results in a cut SiC semiconductor wafer; and
a controller configured to control the cutting tool such that the cut produced by the cutting tool has a specified depth through a portion of a thickness of the SiC semiconductor wafer and a specified width in the gap between the die sections; and

a cleaving apparatus configured to perform a cleaving operation on the cut SiC semiconductor wafer on a second surface of the SiC semiconductor wafer after the cutting operation has been performed on the SiC semiconductor wafer to produce a cleave that results in a separated die, the second surface being opposite the first surface.
