摘要 |
A substrate is held by adsorption by a substrate holding frame that is formed into a frame shape and is lightweight, and the substrate holding frame is driven along a horizontal plane by a drive unit that includes a linear motor. Below the substrate holding frame, a plurality of air levitation units are placed that support by levitation the substrate in a noncontact manner such that the substrate is substantially horizontal, by jetting air to the lower surface of the substrate. Since the plurality of air levitation units cover a movement range of the substrate holding frame, the drive unit can guide the substrate holding frame (substrate) along the horizontal plane at high speed and with high precision. |
