    摘要: In order to reduce an unevenness of a surface of a body, a sacrificial layer is applied to the surface, a chemical-mechanical polishing of the sacrificial layer and material of said body is performed to reduce the unevenness of the surface, and a remainder of the sacrificial layer, if any, may be removed.
