Paper Abstract

SiC is highly anticipated as the material to be used in the next generation of power devices. However, due to its high rigidity, it is difficult to process, has a low throughput in the wafer production process, and has a high cost. In order to solve these issues, we have developed the KABRA process – a new wafer-production process which uses laser processing technology – and have devised fully-automatic equipment called “KABRA!zen,” which enables the mass production of SiC wafers. KABRA!zen achieves approximately twice the throughput and one-third the material loss of the conventional processes.
