Abstract:
1. A substrate mounting mechanism comprising: a heater plate having a substrate mounting surface on which a target substrate is placed and a heater embedded therein to heat the target substrate to a deposition temperature at which a film is deposited; a temperature control jacket formed to cover at least a surface of the heater plate other than the substrate mounting surface and having a non-deposition temperature below the deposition temperature, the temperature control jacket including a temperature control unit and having a disc-shaped bottom plate covering a bottom portion of the heater plate and a ring-shaped sidewall covering a side portion of the heater plate; and a thermal insulator provided between the heater plate and the disc-shaped bottom plate, wherein the thermal insulator has uneven structures including a cylindrical protrusion and a rectangular protrusion on each of a surface facing the heater plate and a surface facing the temperature control jacket.
