Patent Number Title Of Patent Date Issued
6348240 Methods for and products of modification and metallization of oxidizable surfaces, including dia February 19, 2002
The present invention concerns a process for modifying oxidizable surfaces, including diamond surfaces, including methods for metallizing these surfaces, where these methods include oxidation of these surfaces. The present invention also relates to the products of these methods.In this p
6051152 Process for making diamond and diamond-coated filaments April 18, 2000
Filamentous substrates are coated with diamond by a chemical vapor deposition process. The substrate may then be etched away to form a diamond filament, such as a diamond tube or a diamond fiber. In a preferred embodiment, the substrate is copper-coated graphite. The copper initially
5891575 Growing and releasing diamonds April 6, 1999
A process for making diamond and diamond products includes the steps of implanting ions in a diamond substrate to form a damaged layer of non-diamond carbon below the top surface of the substrate, heating the substrate to about 600-1200.degree. C., growing diamond on the top surface
5702586 Polishing diamond surface December 30, 1997
Process of smoothing or polishing a diamond surface to reduce asperities reon to a level as low as about 20 nm from the horizontal by implanting the diamond surface with ions to form a non-diamond carbon damage layer on or below the diamond surface below the disparity depth and dissolvi
5587210 Growing and releasing diamonds December 24, 1996
A process for making diamond and diamond products includes the steps of ianting ions in a diamond substrate to form a damaged layer of non-diamond carbon below the top surface of the substrate, heating the substrate to about 600-1200.degree. C. growing diamond on the top surface of
5374414 Self-supporting diamond filaments December 20, 1994
Filamentous substrates are coated with diamond by a chemical vapor deposin process. The substrate may then be etched away to form a diamond filament. In a preferred embodiment, the substrate is copper-coated graphite. The copper initially passivates the graphite, permitting diamond
5171608 Method of pattern transfer in photolithography using laser induced metallization December 15, 1992
Method for improved photolithography using a laser induced metallization cess to produce a metal mask wherein a work piece surface is treated to have a predetermined pattern of at least two materials each having different electron band gaps, the treated work piece is positioned in a
