Abstract:
1. A substrate processing apparatus for processing substrates within a vacuum processing space, the substrate processing apparatus comprising: a substrate stage for mounting at least two substrates thereon, the substrate stage including substrate stage units whose number corresponds to the number of the substrates mounted on the substrate stage and a connecting portion coupling the substrate stage units, each of the substrate stage units including a central temperature control flow path for controlling the temperature of a central portion of each of the substrates and a peripheral temperature control flow path for controlling the temperature of a peripheral portion of each of the substrates, the central temperature control flow path and the peripheral temperature control flow path being formed independently of each other, the connecting portion being provided with a temperature control medium inlet port for introducing therethrough a temperature control medium into the peripheral temperature control flow path, and the connecting portion being provided with temperature control medium outlet ports for discharging therethrough the temperature control medium from the peripheral temperature control flow path, the number of the temperature control medium outlet ports corresponding to the number of the substrates mounted on the substrate stage, wherein the peripheral temperature control flow path includes:
