Abstract
A maintenance method of a substrate processing apparatus includes a first processing step of carrying a first substrate holder holding a substrate into a process chamber and processing the substrate held by the first substrate holder within the process chamber, a second processing step of carrying a second substrate holder holding a substrate into the process chamber and processing the substrate held by the second substrate holder within the process chamber, a determination step of determining a replacement timing of the first substrate holder and the second substrate holder, and a maintenance step of, at the replacement timing determined at the determination step, replacing the first substrate holder and the second substrate holder respectively with a third substrate holder and a fourth substrate holder, if at least one of the first substrate holder and the second substrate holder reaches the replacement timing.
