Abstract:
In a case where a back surface of an SiC semiconductor wafer, which is provided by a C surface, is covered with a back surface electrode and a scribe line cannot be confirmed, a reference line is formed before dicing. As a result, even when a processing upper surface from which dicing is carried out is a C surface, the dicing can be performed by estimating a scribe line with reference to the reference line. Accordingly, even if the semiconductor wafer is cut at a higher speed than that in the conventional art, a high-quality SiC semiconductor device with less chipping can be manufactured. A blade abrasion can be reduced, and costs can be also reduced.

Claim (Index 2):
The method for manufacturing the silicon carbide semiconductor device according to  claim 1 , wherein\n a region of the semiconductor wafer where the semiconductor element is formed is referred to as an effective region to be divided into chips along the scribe line by the dicing, and a region of the semiconductor wafer outside of the effective region is referred to as an ineffective region, and in the forming of the reference line, the semiconductor wafer is diced from the front surface in the ineffective region so as to form the reference line at a position distant from the effective region.
