Abstract
When processing of all the wafers accommodated in a first cassette mounted on a first cassette stage is ended, the last wafer is conveyed out from a holding surface of a chuck table, and the holding surface becomes vacant, the wafer accommodated in a second cassette mounted on a second cassette stage is immediately conveyed onto the holding surface, by control by a conveyance control section. When the wafer to be held by the holding surface is changed from the wafer conveyed out from the first cassette to the wafer conveyed out from the second cassette, processing conditions are changed over to the processing conditions corresponding to the second cassette stage, by changeover control by a changeover section.
