Sputtering apparatus and electronic device manufacturing method
Abstract:
A sputtering apparatus comprises a substrate holder, and a screening member configured to screen a substrate mount surface of a surface of the substrate holder. The screening member comprises a first screening member configured to rotate about an axis in a first direction perpendicular to the substrate mount surface and screen at least a first area, and a second screening member configured to rotate about the axis and screen at least a second area. The first and second screening members are configured to be rotated to move between a screening position at which the first screening member screens at least the first area and the second screening member screens at least the second area and a retreat position at which the first and second screening members retract from an area above the substrate mount surface and overlap each other.
