  • Patent number: 10468237
    Abstract: An apparatus includes a row of substrate transfer devices 3 which can deliver a wafer W within a transfer chamber; and rows of process modules PM, arranged at right and left sides of the row of the substrate transfer devices along the row, configured to perform processes to the wafer W. The rows of the process modules PM are arranged such that each of the processes can be performed by at least two process modules PM. Thus, when a single process module PM cannot be used, the wafer W can be rapidly transferred to another process module PM which can perform the same process as performed in the corresponding process module. Therefore, even when the single process module PM cannot be used, the processes can be continued to the wafers W without stopping an operation of the apparatus, so that the number of wasted wafers W can be reduced.

  • Patent number: 10273571
    Abstract: A film forming system includes a camera having a field of view in a region through which an edge of a film-formed workpiece rotated by a rotational stage and an edge of the film of the film-formed workpiece pass. Based on three or more images obtained by the camera during the rotation of the film-formed workpiece, widths between the edge of the film-formed workpiece and the edge of the film of the film-formed workpiece at circumferentially different locations are obtained. Based on the widths obtained by the first unit, a first positional deviation of a central position of the film of the film-formed workpiece with respect to a central position of the film-formed workpiece is obtained. By using the first positional deviation of the film-formed workpiece, a transfer position of a transfer modules transferring the workpiece to a film forming apparatus used for producing the film-formed workpiece is corrected.
