Abstract: Films are formed on a plurality of substrates through a batch process while preventing formation of films on the rear surfaces of the substrates. For this, a substrate processing apparatus comprises a reaction vessel, supports, a support holder, and an induction heating device. The reaction vessel is configured to process substrates therein. The supports are made of a conductive material and having a disk shape, and each of the supports is configured to accommodate a substrate in its concave part in a state where the substrate is horizontally positioned with a top surface of the substrate being exposed. The concave part is formed concentrically with a circumference of the support, and a difference between radii of the support and the concave part is greater than a distance between neighboring two of the supports held by the support holder. The support holder is configured to hold at least the supports horizontally in multiple stages.

Abstract: Emissivity of a substrate is measured at least before the substrate is heated, heating operation of the substrate is controlled under a heating condition corresponding to the emissivity, and the substrate is processed.
