Abstract:
1. A substrate housing method for a substrate processing apparatus comprising first and second transport units, the method comprising: delivering a substrate taken out from a housing case to the substrate processing apparatus by the second transport unit; processing the substrate at the substrate processing apparatus; taking the processed substrate from the substrate processing apparatus by the first transport unit and passing the processed substrate to the second transport unit; and returning the processed substrate to the housing case by the second transport unit; wherein after the processing of the substrate at the substrate processing apparatus and before the returning of the processed substrate by the second transport unit, a difference in amount between an actual position of the substrate and a normal position of the substrate at the second transport unit is calculated; and wherein upon delivering the processed substrate from the first transport unit to the second transport unit, a returning position of the substrate in the housing case is adjusted based on the calculated difference in amount.
