Title:

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

Document Type and Number:

WIPO Patent Application WO/2016/013588

Kind Code:

A1

Abstract:

　In a single-crystal diamond (20), groups of crystal defect points (20dp), which are points where distal ends of crystal defect lines (20dq) indicating lines where crystal defects (20d) are present reach a principal crystal growth face (20m), exist as aggregates in an X-ray topogram for the primary crystal growth face (20m). Furthermore, a plurality of crystal defect linear aggregation regions (20r) in which a group of crystal defect points (20dp) aggregates and extends linearly in a direction 30° or less from an arbitrarily specified direction are arranged in rows in the single-crystal diamond (20). A single-crystal diamond is thereby provided that is suitable for use in a cutting tool, a polishing tool, an optical component, an electronic component, a semiconductor material, or the like.
