Abstract

A substrate processing apparatus is disclosed for heating a substrate by a heater through a susceptor in a state in which the substrate is placed on the susceptor, to process the substrate. The heater is divided into a plurality of respectively controlled zone heaters to form gaps therebetween, a center position of a gap of the gaps which is positioned closer to an end of the substrate than any other gap is located in a range from an inner side 10 mm to an outer side 6 mm in a radial direction of the substrate with respect to the end of the substrate.
