Abstract:
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 it 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 a 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 chamber; each of the said connection terminal holders holds a plurality of connection terminals at a predetermined position with electrically insulating therebetween; each of the said connection terminals connects the heating elements to the power supply mechanism electrically; the said heating elements connected to the connection terminals are supported in face with 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.
