Zusammenfassung:A substrate processing apparatus includes a chuck configured to attract and hold a substrate; an observer configured to observe multiple positions within a second surface of the substrate attracted to and held by the chuck, the second surface being opposite to a first surface thereof which is in contact with the chuck; and an analyzer configured to analyze observation results of the multiple positions. When a singularity regarding a height from a surface of the chuck attracting and holding the substrate exists on the second surface, the analyzer specifies a position of the singularity on the chuck.
