Claim Text:
1. A method for sputtering a thin film on a substrate, comprising: providing a sputtering device comprising: sputtering to form a first layer in a first facing mode where magnetic flux-lines are formed between the first and second targets, and in the first facing mode the controller controls electrical energy to the non-sputtering electromagnets so that each non-sputtering electromagnet has an opposite pole direction as that of an adjacent other pole element of the respective other pole group while no electrical energy is sent to the first and second electromagnets; sputtering to form a second layer in a second facing mode where magnetic flux-lines are formed between the first and second targets, and in the second facing mode the controller controls sputtering to form a third layer in a mixed mode where magnetic flux-lines are formed between the first and second targets and each of the first and second targets has formed thereupon curved magnet flux-lines that curve back thereupon, the controller controlling
