In a vacuum transfer chamber 10, a position detecting mechanism 33 for detecting the positions of semiconductor wafers W is arranged. The semiconductor wafers W disposed at predetermined positions in a load lock chamber 17 and vacuum processing chambers 11 to 16 are transferred to the position detecting mechanism 33 by a vacuum transfer mechanism 30 and the positions of the wafers are detected. Then, based on the detection results, aligning between the load lock chamber 17 and the vacuum processing chambers 11 to 16 is performed.
