Classification: CPC H  C | IPC C  H

Claim 0:
1. A thin-film-deposition equipment with shielding device, comprising:
a reaction chamber comprising a containing space;
a carrier disposed within the containing space and including a carrying surface for carrying at least one substrate thereon; and
a first shield member disposed within the containing space and including a first shield protrusion and a first sensing region, wherein the first shield protrusion and the first sensing region are disposed adjacent to each other on a surface of the first shield member which does not face the carrier;
a second shield member disposed within the containing space and including a second shield protrusion and a second sensing region, wherein the second shield protrusion and the second sensing region are disposed adjacent to each other on a surface of the second shield member which does not face the carrier;
at least one driver interconnecting the first shield member and the second shield member to respectively drive and swing the first shield member and the second shield member in opposite directions and switch 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 to shield the carrier; and wherein in the open state, the first shield member and the second shield member define an open space therebetween; and
at least two optical sensors disposed on the reaction chamber, for respectively detecting the first sensing region of the first shield member and the second sensing region of the second shield member and thereby to confirm that the first shield member and the second shield are operated into the open state.
