On a wafer holding area 50 on the upper surface of a susceptor 22, a wafer W is supported by a wafer support 54 such that a gap with a predetermined distance is formed between the wafer W and a wafer heating surface 52. A projection 58 that decreases the distance of the gap with respect to the wafer W is formed on the wafer heating surface 52. At this time, the heating condition for the wafer W by the susceptor 22 is adjusted by means of the distances of the gaps at the respective portions of the wafer holding area 50 . Thus, the uniformity of the planar temperature distribution of the wafer W and that of the thickness distribution of the formed film can be improved.
