Abstract: A fixture, a tray and a sputtering system. The fixture is internally provided with a support structure and a clamping structure connected with each other, wherein the clamping structure is configured to clamp a to-be-sputtered substrate; an orthographic projection of the clamping structure on a plane where the support structure is located and the support structure share an superimposed area and are separate in non-superimposed areas; wherein the support structure located in the non-superimposed area and/or the clamping structure located in the non-superimposed area has a first hollowed structure. The fixture is internally provided with the first hollowed structure, such that a part of an area of the to-be-sputtered substrate covered by the fixture may be exposed via the first hollowed structure when the fixture holds the to-be-sputtered substrate, so as to reduce the area of the to-be-sputtered substrate covered by the fixture.
