  • Methods for forming smooth diamond-based mesa structures
    Patent number: 5672240
    Abstract: A diamond-based structure includes a substrate, an adhesive material on a face of the substrate, and an array of spaced apart diamond mesas bonded to the substrate by the adhesive material. In particular, each of the diamond mesas can have a growth surface adjacent the substrate and an interfacial surface opposite the substrate, and the interfacial surface can be smooth relative to the growth surface. This structure can be fabricated by providing a sacrificial substrate, forming a plurality of diamond mesas on a face of the sacrificial substrate, bonding the diamond mesas to a transfer substrate, and removing the sacrificial substrate. Accordingly, the interfacial surfaces of the diamond, which are formed adjacent the sacrificial substrate and then exposed by removing the substrate are smooth.
    Type: Grant
    Filed: June 5, 1996
    Date of Patent: September 30, 1997
    Assignee: Kobe Steel USA Inc.
    Inventors: Brian R. Stoner, Joseph S. Holmes, Jr., David L. Dreifus, Scott R. Sahaida, Roy E. Fauber, Michelle L. Hartsell, Dean Malta
