Abstract

The invention relates to a sputtering target, a coating system, and a coating method for same. The sputtering target comprises a base plate with a target plate which is secured thereon and which is made of a first sputtering material with a surface and a plurality of recesses formed therein. A plurality of inserts are arranged in the recesses. At least some of the inserts are made of a second sputtering material, wherein the second sputtering material has a higher sputter yield than the first sputtering material. The aim of the invention is to achieve especially uniform coatings. This is achieved in that the inserts made of the second sputtering material are shaped such that the extent D1, D2 of the inserts, measured in a measuring direction parallel to the surface, increases from the surface to the base plate in a depth direction T.
