The present disclosure provides a thin-film-deposition equipment with double-layer shielding device, which includes a reaction chamber, a carrier and a double-layer shielding device. The double-layer shielding device includes a first-shield member, a second-shield member, a first-guard plate, a second-guard plate and a driver. The first-guard plate is disposed on the first-shield member, the second-guard plate is disposed on the second-shield member. The driver interconnects the two shield members for driving and swinging the two shield members to move in opposite directions. During a cleaning process, the driver swings the two shield members toward each other into a shielding state for covering the carrier, the two guard plates thereon also approach each other to cover the shield members, such that to effectively prevent polluting the carrier during the process of cleaning the thin-film-deposition equipment.
