Patent ID: 8663437

Claim:
A deposition apparatus comprising: a processing chamber configured to perform deposition processing; an exhaust chamber connected to said processing chamber via an exhaust port; an exhaust device connected to said exhaust chamber, which evacuates said processing chamber via said exhaust chamber; a substrate holder disposed in said processing chamber, which supports a substrate; a deposition unit comprising a target holder capable of holding a target disposed in said processing chamber, which deposits a film on the substrate; a shutter configured to move to a shielding state in which said shutter shields said substrate holder and said deposition unit from each other, or a retracted state in which said shutter is retracted from between said substrate holder and said deposition unit; a driving unit configured to drive said shutter to set said shutter in the shielding state or the retracted state; a shutter storage unit arranged in said exhaust chamber and connected to said processing chamber via an opening, wherein which said shutter is stored in said shutter storage unit in the retracted state; and a shield member formed around the opening of said shutter storage unit and configured to cover the exhaust port of said exhaust chamber, wherein said shield member has, at a position on a side of said deposition unit with respect to the opening of said shutter storage unit, a first exhaust path which communicates with the exhaust port of said exhaust chamber, wherein said shield member includes a first shield which has an opening at a position corresponding to the opening of said shutter storage unit and covers the exhaust port, and a second shield which is arranged at a position on a side of said deposition unit with respect to the opening of said shutter storage unit, and a gap between the first shield and the second shield forms the first exhaust path above the shutter storage unit communicating with the exhaust port of said exhaust chamber, wherein said shield member further includes a third shield coupled to the substrate holder and covers the exhaust port, and a gap between the first shield and the third shield forms a second exhaust path below the shutter storage unit communicating with the exhaust port of said exhaust chamber, wherein a distal end of the first shield has a recess, a distal end of the second shield has a projection, the projection is fitted in the recess in a noncontact manner, and a gap between the projection and the recess forms the first exhaust path.
