Claim Text:
1. A deposition device comprising: a processing container configured to accommodate a workpiece and be vacuum exhaustible in order to form a thin film on a surface of the workpiece using a source gas including an organometallic compound; a mounting platform accommodated in the processing container and configured to mount the workpiece, the mounting platform being equipped with a heater for heating the workpiece; a gas introduction mechanism including a baffle plate disposed above the mounting platform to be opposed thereto and configured to introduce the source gas toward an area further outside than an outer peripheral end of the workpiece on the mounting platform; an internal partition wall that surrounds a processing space above the mounting platform to form a boundary for the processing space and installed such that a lower end portion of the internal partition wall comes close to the mounting platform to form a gas outlet between the lower end portion of the internal partition wall and a peripheral edge of a top surface of the mounting platform; and an orifice forming member installed on the lower end portion of the internal partition wall surrounding the processing space to extend toward a central portion of the processing space to form an orifice communicating with the gas outlet between the internal partition wall and the peripheral edge of the top surface of the mounting platform.
