Abstract
Disclosed is a method of planarizing a diamond film which generally includes orifices in the surface. The method includes first polishing the diamond film surface to reduce the surface roughness. Next, a filler material is applied to the surface of the film to fill the orifices in the film. Finally, the film is polished to remove excess filler material and expose the diamond film surface. Also disclosed are planarized diamond films diamond substrate having a polished surface of both diamond and filler material and a variation in thickness of less than 8 percent.
Claims27
A method of processing a diamond film having a surface defining a multiplicity of orifices, the method comprising:
- (a) contacting the diamond film surface with a filler material to overfill at least one of the orifices;
- and
- (b) polishing the surface of the film to remove overfilled filler material, exposing the diamond surface and creating a polished and planarized diamond and filler surface.
A method of processing a diamond film comprising:
- (a) polishing the diamond film to create a polished diamond film surface having orifices on the surface;
- (b) contacting the diamond film surface with a filler material to overfill at least one of the orifices;
- and
- (c) polishing the surface of the film to remove overfilled filler material, expose the diamond surface and create a polished diamond and filler surface.
A method of processing a diamond film comprising:
- (a) polishing the diamond film to create a polished diamond film surface having orifices on the surface;
- and
- (b) contacting the diamond film surface with a filler material to overfill at least one of the orifices.
A planarized diamond film comprising a diamond substrate with a polished surface area comprising both a polished diamond surface area and a polished filler material surface area, wherein the polished diamond surface area defines a multiplicity of orifices which contain the filler material.
