Abstract
A diamond body and an oxide substrate are simultaneously sputter-etched such that the diamond body is cleaned and a layer of the sputtered oxide is deposited on the clean surface of the diamond body, then a metallic layer is deposited on the oxide layer. This provides a metallized diamond body whose metallic layer will adhere to the body.
