  • Patent number: 6770149
    Abstract: A method for a cleaning treatment including a step of forming, in a coating mechanism, a coating film on a substrate provided within a cup. The method further includes dissolving, in an edge cleaning mechanism, a portion of the coating film on the substrate using a cleaning liquid, and recovering at least a portion of used cleaning liquid from the edge cleaning mechanism. The recovered cleaning liquid is stored and a level of the stored cleaning liquid is detected. The method also includes supplementing a fresh cleaning liquid to the stored cleaning liquid when a detected level of the stored cleaning liquid is lower than a predetermined level, and using a mixture of the supplemented fresh cleaning liquid and the stored cleaning liquid to clean the cup of the coating mechanism.

  • Patent number: 6261378
    Abstract: A cleaning unit for cleaning a substrate is disclosed, that comprises a holding mechanism for rotatably and horizontally holding the substrate, a first traveling means for holding both sides of a cleaning mechanism having at least one cleaning member and for moving the cleaning mechanism in such a manner that the first traveling means is kept in parallel with the substrate held by the holding mechanism, and a second traveling means for holding both sides of a processing solution supplying mechanism having supplying mechanisms for supplying different types of processing solution and for moving the cleaning mechanism in such a manner that the second traveling means is kept in parallel with the substrate held by the holding mechanism. Thus, the strength of the cleaning unit according to the present invention is higher than the strength of a conventional cleaning unit that holds an arm on one side thereof.

  • Patent number: 6198481
    Abstract: The present invention is to offer a remote control transmission apparatus which permits learning of control data for a plurality of devices without increasing the number of operating areas (kn) on the operating panel and provides a clear indication of the relationship between each operating area (kn) and the contents of control at the time when that operating area (kn) is pressed. In the learning mode, control data detected from a received remote control signal are stored in correspondence with a predetermined operating area (kn), and a predetermined one of plural icons is stored in correspondence with a predetermined operating area (kn). In the transmission mode, the contents of control at the time when the operating area (kn) is pressed can be displayed by the selected icon, providing a clear indication of their relationship and hence preventing a user from erroneous remote control operation.

  • Patent number: 5945161
    Abstract: Disclosed is a processing apparatus comprising holding means, support means, process solution supply means, life means, and rotating means. A substrate to be processed is rotatably held by the holding means. An overhanging portion of the substrate extending over an edge of the holding means is supported by the support means to maintain a front surface of the substrate horizontally flat. A process solution is supplied from the process solution supply means onto the front surface of the substrate held by the holding means and supported by the support means. The substrate held by the holding means is vertically moved by the lift means relative to the support means. Further, the substrate moved upward relative to the support means is rotated by the rotating means.
