Claim 8:
9. A thin-film-deposition equipment, comprising:
a reaction chamber comprising a containing space;
a carrier disposed within the containing space for carrying at least one substrate; and
a shielding device comprising:
a first-shield member that is disposed within the containing space,
a second-shield member that is disposed within the containing space,
a driver that interconnects the first-shield member and the second-shield member for respectively driving and swinging the first-shield member and the second-shield member to move in opposite directions and between an open state and a shielding state, wherein in the shielding state, the first-shield member and the second-shield member approach each other and be adjacent to each other for covering the carrier, wherein: the first-shield member of the shielding device comprises a first-inner surface formed with at least one protrusion; the second-shield member of the shielding device comprises a second-inner surface formed with at least one cavity; the at least one protrusion on the first-inner surface corresponds to the at least one cavity on the second-inner surface; and in the shielding state, the first-inner surface of the first-shield member and the second-inner surface of the second-shield member are adjacent to each other, the at least one protrusion on the first-inner surface enters the at least one cavity on the second-inner surface, the first-shield member and the second-shield member together cover the carrier.
