Abstract:
The present invention provides a carbon film coated member comprising: a base material; and a coated film formed on at least part of a surface of the base material, the coated film comprising: a matrix composed of amorphous carbon; and at least one of metal and metal carbide contained in the matrix, wherein an atomic ratio (M/C) of the metal (M) to carbon (C) constituting the coated film is 0.01 to 0.7. According to the above structure, there can be provided a carbon film coated member excellent in low-friction property, wear resistance and durability, and capable of suppressing a dust generation, peeling-off and deterioration of the coated film even if the carbon film coated member is used as semiconductor equipment members such as wafer cassette, dummy wafer, probe pin or the like under severe operating conditions, so that the carbon film coated member would not exert a bad influence onto the resultant semiconductor products.
