Abstract
A substrate processing apparatus includes: a substrate transfer controller that determines a placement condition of the substrate holder and a substrate placement position on the substrate holder based on a model, a substrate transfer position setting value, and a substrate holder setting value from the film thickness measurement result, and operates the substrate transfer device; an eccentricity status analysis unit that analyzes an eccentric state from a film thickness variation state; a learning function unit that updates the model based on the eccentric state; and an optimization function unit that updates the placement condition of the substrate holder and the substrate placement position on the substrate holder based on the updated model, the substrate transfer position setting value, and the substrate holder setting value.
