  • Patent number: 8997822
    Abstract: According to an embodiment of the present disclosure, a substrate inverting device for inverting front and rear surfaces of a substrate is provided. The substrate includes a first holding unit configured to hold one surface of the substrate and a second holding unit disposed to face the first holding unit and configured to hold one surface of the substrate. Further, the substrate includes a moving mechanism configured to relatively move at least one of the first holding unit and the second holding unit to approach each other and stay spaced apart from each other, and a transfer mechanism configured to hold the one surface of the substrate. In this case, a support of the substrate in the first holding unit, the second holding unit and the transfer mechanism is performed by a Bernoulli chuck.

  • Publication number: 20020053321
    Abstract: A plurality of production line recipes and film thickness measurement recipes that recite the same type of coating solution, but different target film thickness are prepared in a coating unit. Recipes that recite the same types of coating solution and the same film thickness are linked to a common spin curve. A film thickness measurement recipe is executed so as to calculate a compensated value for a revolving speed for each measured data of the film thickness. The designated values of revolving speeds of individual recipes can be compensated using the compensated value at a time.
