Silicon Carbide and Related Materials 2017

Abstract: The disloion behavior during bulk crystal growth on the 4H-SiC (000-1) C-face using the solution method was investigated. A 2 inch wafer with a 4° off angle was fabried from a bulk crystal grown by the TSSG method, and the disloions in the crystal were evaluated using synchrotron X-ray topography and TEM observation.

Technical Report UDC 661 . 665 : 548 . 55 Development of

When a SiC crystal is grown using the TSSG method, the presence of a low temperature part other than the vicinity of the seed crystal causes spontaneous nucleation, which will bring about the growth of undesirable crystals. Undesirable crystals hinder the growth of a single crystal. As shown in Fig. 3, undesirable crystals

High-Temperature Chemical Vapor Deposition for SiC Single

SiC single bulk crystals were grown using a high-temperature chemical vapor deposition (HTCVD) method, with SiH4 and hydrocarbons as the source materials.
