Abstract:
1. A heating element CVD system comprising: a processing container in which a predetermined processing is performed to a substrate held by a substrate holder disposed therein; an evacuation system which is connected to the processing container and evacuates the processing container to a vacuum; a raw material gas supply system for supplying a predetermined raw material gas into the processing container; and a heating element which is disposed in the processing container and is supplied with electric power from an electric power supply mechanism, thereby being heated to high temperatures; wherein the raw material gas introduced into the processing container from the raw material gas supply system is decomposed and/or activated by the heating element kept at high temperatures to form a thin film on the substrate held by the substrate holder; wherein one or a plurality of connection terminal holders is placed in the processing container, each of the connection terminal holders holds a plurality of connection terminals at a predetermined position with electrical insulation therebetween; each of the connection terminals connects the heating element to the electric power supply mechanism electrically; the heating element connected to the connection terminals is supported facing the substrate holder; and a connection region of the heating element connected to the connection terminal is not exposed to a space in the processing container, and further comprising a shield plate having a heating element passing hole through which the heating element passes in a noncontact manner and a plurality of through holes for passing gas is arranged between a part of the heating element extending into the processing container through the heating element passing hole and a surface of the connection terminal holder facing the inside of processing container.
