SILICON CARBIDE SUBSTRATE, METHOD FOR MANUFACTURING SILICON CARBIDE SUBSTRATE, SILICON CARBIDE SEMICONDUCTOR DEVICE, AND METHOD FOR MANUFACTURING SILICON CARBIDE SEMICONDUCTOR DEVICE
Before epitaxial growth of an epitaxial layer (40) including a buffer layer (11), a crystal defect introduction region (41) is formed by introducing point defects (42) at high density from a front surface (1a) of a starting substrate (1). Since an Si core partial dislocation of a BPD (30) becomes less likely to move in the vicinity of the front surface (1a) of the starting substrate (1) due to the crystal defect introduction region (41), even if the in-plane temperature distribution of the front surface (1a) of the starting substrate (1) is unstable during the epitaxial growth of the epitaxial layer (40), the distance between two Shockley partial dislocations constituting the BPD (30) in the starting substrate is less likely to increase, and the BPD (30) in the starting substrate (1) is converted into a TED (31) with high efficiency at an interface (12) between the starting substrate (1) and the buffer layer (11), and is less likely to propagate to the epitaxial layer (40). Consequently, the propagation of the BPD (30) in the starting substrate (1) to the epitaxial layer (40) can be suppressed.
