Abstract:
A sputter coating chamber with a sputter source, comprising: at least two electrically mutually isolated stationary bar-shaped target arrangements, mounted one alongside the other and separated by respective slits; each of said target arrangements comprising a respective electric pad so that each of said target arrangements may be operated electrically independently from the other target arrangement; each target arrangement comprising a controlled magnet arrangement generating a time varying magnetron field upon the respective target arrangement and thus forming a magnetron sputtering source; a substrate holder for at least one substrate to be sputter-coated, said holder being arranged distant and opposite to said magnetron sputtering source, the ratio VQS of a sputtering surface (FQ) said sputter source to a surface (FS) of a substrate held by said substrate holder and to be sputter-coated being VQS&lE;3.
