Abstract
Diamond-containing articles such as composite materials shaped as some specific article, can be engineered such that bodies that contact the article only contact diamond. In an embodiment, the article may be in the form of equipment for handling semiconductor wafers such as vacuum or electrostatic chucks. In one embodiment, the diamond-containing article can be a composite of diamond particulate reinforcing a Si/SiC body such as reaction-bonded SiC. Lapping the diamond-reinforced RBSC body with progressively finer diamond grit removes some of the SiC/Si matrix material, leaving diamond particles of uniform height 'standing proud' above the rest of the surface of the formed article. Further, if the diamond-containing article is sufficiently electrically conductive, it may be machinable using electrical discharge machining.
