Classification: CPC H  C | IPC C  H

Claim 14:
15. The method of claim 2,
wherein the substrate is disposed on a stage provided with a plurality of zones and configured such that temperatures of the plurality of zones are independently controllable,
(a) and (b) are repeated at least n″ times (n″ is a natural number of 2 or more),
in (b-2) of an (n″-1)-th processing, each of the plurality of zones is controlled to be a first temperature distribution, thereby forming a first film having a first film thickness distribution in a depth direction, and
in (b-2) of an n″-th processing, each of the plurality of zones is controlled to be a second temperature distribution, thereby forming a second film having a second film thickness distribution in the depth direction.
