The present disclosure provides a wafer-holding device and a deposition equipment using the same, wherein the wafer-holding device includes a carrier, a first-lid ring and a second-lid ring. The carrier has a carrying surface for carrying a wafer thereon, and includes a first aligner disposed to enclose the carrying surface. The second-lid ring is connected to the first-lid ring, and includes a second aligner. The first-lid ring has a circumference larger than that of the second-lid ring, for carrying the second-lid ring thereon. The carrier is movable, and when the carrier carries the wafer thereon toward the lid rings, the first aligner thereon contacts, engages with the second aligner of the second-lid ring, thereby the second aligner is positioned to contact a specific area of the wafer and hold the wafer on the carrier, for the deposition equipment to perform a thin-film-deposition process to the wafer.

Electron beam inspection apparatus stage positioning

An electron beam apparatus includes an electron optics system to generate an electron beam, an object table to hold the specimen at a target position so that a target portion of the specimen is irradiated by the electron beam, and a positioning device to displace the object table relative to the electron beam. The positioning device includes a stage actuator and a balance mass. The stage actuator exerts a force onto the object table to cause an acceleration of the object table. The force onto the object table results in a reaction force onto the balance mass. The balance mass moves in response to the reaction force. The positioning device enables the balance mass to move in a first direction in response to a component of the reaction force in the first direction.
