PURPOSE: To reduce influence on rate limiting due to other treatment parts. CONSTITUTION: The system consists of a load/unload part 2 which carries an untreated wafer into each treatment unit and unloads a treated wafer W from each of the treatment units, a sub-arm mechanism which is provided to each treatment unit accessibly, delivers a wafer W between it and the load/unload part 2 and carries a wafer W to each treatment unit one by one and a controller 13, which controls each part to carry out treatment by each treatment unit one by one by applying a maximum duration tn/m per unit, which is obtained by dividing the duration tn of each treatment unit by a number (m) of the treatment units as a single cycle, and sets a prewaiting time by a heat treatment system unit.
