Abstract:
1. A catalytic CVD equipment for performing formation of film by supplying a raw material gas to a catalytic wire that is installed and heated in a reaction chamber and then depositing generated decomposed species on a substrate that is held on a holder in the reaction chamber, the holder including an antireflective structure for preventing reflection of a radiant ray that is ejected from the catalytic wire, wherein the antireflective structure includes an antireflective film having a thickness of about 1.5 microns to 3 microns and has a concave-convex structure that is provided so as to be opposed to the substrate, wherein the antireflective film is provided on a surface of the holder facing a back surface of the substrate, and wherein the holder has a substrate portion on which the antireflective film is formed, and the substrate portion is made of aluminum or stainless steel.
