SINGLE-CRYSTAL DIAMOND AND METHOD FOR MANUFACTURING SAME TOOL INCLUDING SINGLE-CRYSTAL DIAMOND AND COMPONENT INCLUDING SINGLE-CRYSTAL DIAMOND

摘要

The single crystal diamond 20 is a point at the tip of the crystal growth main surface 20m at which the crystal defect line 20dq indicating the line in which the crystal defects 20d exist on the X-ray topography with respect to the crystal growth main surface 20m reaches the crystal growth main surface 20m And a group of crystal defect points (20dp) collectively exist. In the single crystal diamond 20, a plurality of crystal defective linear aggregate regions 20r extending linearly in a direction within 30 占 from a direction in which a group of crystal defect points (20dp) collectively and arbitrarily specified are present in parallel do. Accordingly, there is provided a single crystal diamond suitably used for a cutting tool, an abrasive tool, an optical component, an electronic component, a semiconductor material, and the like.
