摘要:
A vapor-phase deposition apparatus comprises substrate-supporting unit (4, 10, 11) for supporting a substrate (3), heater (6) for heating substrate-supporting unit (4, 10, 11), and gas-supplying unit (9) for supplying gas for forming a thin film on the substrate (3) supported by the substrate-supporting unit (4, 10, 11). The substrate-supporting unit (4, 10, 11) includes a first member (4) to be heated to a predetermined temperature by the heater (6), a second member (10) for supporting a peripheral part of the substrate (3), and a support member (11) for supporting the second member (10) on the first member (4) and located outside a periphery of the substrate (3).
