Device 10 with magnet assemblies 60,74,82,90,98 and 106 is arranged in process chamber 42.Therefore, plasma
Scope also limited by magnet assemblies 60,74,82,90,98 and 106.Plasma include with positive charge ion and
Electronics with negative electrical charge.The drift of electronics and electronics in plasma to produce more polyion, and the ion should be then
Material granule on target is hit.This represents the erosion of electronic effect target.Especially, the drift of electronics and and then more
The generation of ion should be influenceed by magnet assemblies 60,74,82,90,98 and 106.The path of plasma flow, particularly respective
Magnet assemblies 60,74,82,90,98 and 106 in or surrounding flowing path, and respective target erosion is referred to as plasma
Track body (plasma racetrack).For example, plasma is by respective magnet assemblies 60,74,82,90,98 and 106
Configuration defined.Electronics is exposed to electric field and magnetic field.The power for acting on electronics is so-called Lorentz force (Lorentz
force).Lorentz force is defined by below equation：F (Lorentz)=q* (E+v x B), wherein q are charged particle (electronics)
Electric charge, E be electric field field intensity, v be charged particle speed, B be magnetic field magnetic flux density.
Due to acting on the power of electronics, single electronics is produced for each magnet assemblies 60,74,82,90,98 and 106
Drift current.Single electronics drift sense of current passes through in respective magnet assemblies 60,74,82,90,98 and 106
The polarity of magnet string and the polarity of external magnet string and define, therefore defined by the direction of each self-magnetic field.Especially, individually
Electronics drift current flowed between the internal magnet string and external magnet string of respective magnet assemblies 60,74,82,90,98 and 106
It is dynamic.The example of the electronics drift current is indicated in Fig. 4.Fig. 4 illustrates the electronics drift current related to magnet assemblies 60
126th, the electronics drift current 128 related to magnet assemblies 74, the electronics drift current 130 and magnetic related with magnet assemblies 82

106 related electronics drift currents 136.The direction that electronics drift current 126 to 136 flows is indicated with arrow in Fig. 4.Can be with
It is noted that individually the direction of electronics drift current 126 to 136 replaces between magnet assemblies.Such case is due to
The magnetic polarity of external magnet string and the magnetic polarity of internal magnet string replace caused between magnet assemblies.Electronics drift current 126,
130 and 134 flow in the counterclockwise direction, and electronics drift current 128,132 and 136 flows along clockwise direction.
The flowing of respective electronics drift current is limited along plasma to be flowed, and the plasma limitation has two
Parallel and linear core (left center part 138 and right core 140) and two turn-around portions (on around transfer part
Divide 142 and lower turn-around portion 144).In respective magnet assemblies 60,74,82,90,98 and 106, left center part 138 is on a left side

The connection left center part of transfer part point 144 138 and the lower end of right core 140.
Normally, the plasma density of turn-around portion 142,144 and the plasma density of core 138,140 be not
Together.Such case can cause the local erosion of target different.Uneven phenomenon occurs for the target erosion during sputtering process.Keep away
The measure for exempting from this phenomenon is the magnetic field for weakening turn-around portion 142,144.For example, the measure can be by by current divider (shunts)
Reach applied to the magnet string in turn-around portion 142,144.Current divider is, for example, feeromagnetic metal piece.This can reduce turn-around portion
142nd, 144 target erosion.However, the side effect of the relatively low-intensity magnetic field of turn-around portion 142,144 is weaker local plasma
Limitation, this can cause the electrical losses of peripheral part of the magnet assemblies of negative electrode and negative electrode.Especially, in electronics drift current
Electronics is reentered before core 138,140, and electrical losses are serious in the end of turn-around portion 142,144.
