EMBEDDED SINGLE CRYSTAL DIAMOND(S) IN A POLYCRYSTALLINE DIAMOND STRUCTURE AND A METHOD OF GROWING IT

Abstract

A method of a growing an embedded single crystal diamond structure, comprising: disposing a single crystal diamond on a non-diamond substrate, wherein the non-diamond substrate is larger than the single crystal diamond; masking a top portion of the single crystal diamond using a masking material; and using a chemical vapor deposition (CVD) growth chamber, growing polycrystalline diamond material surrounding the single crystal diamond in order to join the single crystal diamond to the polycrystalline diamond material.
