Abstract: Provided is an article having a metal oxide coating employing a novel configuration exhibiting both color and metallic luster. The article having a metal oxide coating disclosed herein is provided with a base material including a metal material and a metal oxide coating including a metal oxide coated onto the surface of the base material. The metal oxide coating is formed by polishing the surface of the base material, using particles composed of the metal oxide.

Abstract: A sliding member is characterized in that a sliding surface of the sliding member is coated with an amorphous hard carbon film, and a surface of the amorphous hard carbon film has a ten-point mean roughness of equal to or less than 0.7 micrometers and an initial wear height in a range of 0.07 to 0.14 micrometers.

Abstract: Top and bottom surfaces of a gate insulating film are terminated with fluorine atoms and the top surface of the gate insulating film is then etched. New dangling bonds are formed on the top surface of the gate insulating film. Such new dangling bonds are terminated with nitrogen atoms. A semiconductor device is thus obtained that has a silicon substrate and a gate insulating film formed on the silicon substrate and that almost all dangling bonds on the top surface of the gate insulating film are terminated with nitrogen atoms and almost all dangling bonds on the bottom surface contacting the silicon substrate are terminated with fluorine atoms.
