Claim 13:
14. A substrate treatment method, comprising:
generating, for each of a plurality of layers constituting a stacked film on a substrate, a captured image of the substrate after a treatment regarding a relevant layer, wherein the captured image includes a table associating coordinates of a plurality of regions of the substrate with corresponding pixel values, each pixel value representing red, green, blue values of a corresponding region of the substrate;
acquiring information indicating a dimension estimated based on the captured image for each of the plurality of layers including an outermost layer of the stacked film on the substrate; wherein
the dimension of each of the plurality of layers constituting the stacked film on the substrate is estimated based on the captured image of the substrate generated for the relevant layer; and
the substrate treatment method further comprises:
deciding a condition of a treatment on the substrate on which the stacked film has been formed, based on an acquisition result of acquiring the information indicating the dimension, wherein
the deciding the condition of the treatment includes deciding the condition of the treatment in a downstream process based on the dimensions of the plurality of layers.
