Abstract:
According to the embodiment, a suction stage includes a mounting section configured to mount a first substrate, and an evacuation section configured to evacuate air between the first substrate and the mounting section. The mounting section includes a first wall part provided on an outer peripheral side of one end surface of the mounting section and shaped like a ring, and a second wall part provided inside the first wall part and shaped like a ring. The evacuation section includes a first control valve provided between the evacuation section and a first region between the first wall part and the second wall part, a second control valve provided between the evacuation section and a second region inside the second wall part, and a control section configured to control the first control valve and the second control valve. The control section is configured to control the first control valve and the second control valve so that suction of the first substrate and deactivation of the suction of the first substrate are alternately performed in at least one of the first region and the second region. While the suction of the first substrate is deactivated in one of the first region and the second region, the suction of the first substrate is performed in the other region.
Abstract:
The embodiment of a substrate treatment device includes a treatment bath configured to store a treatment liquid in which a treatment object is to be immersed, a transport section configured to transport the treatment object, a temperature control section provided in at least one of the treatment bath and a position spaced from the treatment bath and configured to perform at least one of heating and cooling of the treatment object. the treatment object is at least one of: a laminated substrate including a device substrate, a support substrate, and an adhesive provided between the device substrate and the support substrate, the device substrate with the adhesive attached thereto, and the support substrate with the adhesive attached thereto.
Abstract:
A suction stage may include a mounting section configured to mount a first substrate, and an evacuation section configured to evacuate air between the first substrate and the mounting section. The mounting section includes a ring-shaped first wall part, and a ring-shaped second wall part inside the first wall part. The evacuation section includes a first control valve between the evacuation section and a first region between the first and second wall parts, a second control valve between the evacuation section and a second region inside the second wall part, and a control section configured to control the valves. The control section is configured to control the valves so that suction and non-suction of the first substrate are alternately performed in at least one of the regions. Thus, suction of the first substrate may be deactivated in one of the regions, while the suction is active in the other region.
