The device 10 with magnet assemblies 60,74,82,90,98 and 106 is arranged in process chamber 42.Therefore, the scope of plasma also limit by magnet assemblies 60,74,82,90,98 and 106.Plasma comprises the ion with positive charge and the electronics with negative electrical charge.The drift of electronics and electronics in order to produce more polyion in plasma, and the material granule on target should then hit by described ion.This represents the erosion of electronic effect target.Especially, electronics drift and and then more polyionic generation should affect by magnet assemblies 60,74,82,90,98 and 106.The path of plasma flow, particularly in respective magnet assemblies 60,74,82,90,98 and 106 or the path of ambient dynamic, and respective target erosion, be called as plasma track (plasma racetrack).For example, plasma defined by the configuration of respective magnet assemblies 60,74,82,90,98 and 106.Electronics is exposed to Electric and magnetic fields.The power acting on electronics is so-called Lorentz force (Lorentz force).Lorentz force defined by following formula: F (Lorentz)=q* (E+v x B), wherein q is the electric charge of charged particle (electronics), and E is the field intensity of electric field, and v is the speed of charged particle, and B is the magnetic flux density in magnetic field.
Owing to acting on the power of electronics, produce independent electron drift electric current for each magnet assemblies 60,74,82,90,98 and 106.Independent electron drift sense of current is defined by the polarity of internal magnet string of respective magnet assemblies 60,74,82,90,98 and 106 and the polarity of external magnet string, is therefore defined by the direction of each self-magnetic field.Especially, independent electron drift electric current flows between the internal magnet string and external magnet string of respective magnet assemblies 60,74,82,90,98 and 106.Indicate the example of described electron drift electric current in the diagram.Fig. 4 illustrates the electron drift electric current 126 relevant to magnet assemblies 60, the electron drift electric current 128 relevant with magnet assemblies 74, the electron drift electric current 130 relevant with magnet assemblies 82, the electron drift electric current 132 relevant with magnet assemblies 90, the electron drift electric current 134 relevant with magnet assemblies 98 and the electron drift electric current 136 relevant with magnet assemblies 106.The direction of electron drift electric current 126 to 136 flowing indicates with arrow in the diagram.It is possible to note that the direction of independent electron drift electric current 126 to 136 replaces between magnet assemblies.This situation is because the magnetic polarity of external magnet string and the magnetic polarity of internal magnet string replace caused between magnet assemblies.Electron drift electric current 126,130 and 134 flows in the counterclockwise direction, and electron drift electric current 128,132 and 136 flows along clockwise direction.
The flowing of respective electron drift electric current is along plasma restriction flowing, and described plasma restriction has two parallel and linear core (LC part 138 and right core 140) and two turn-around portion (upper turn-around portion 142 and lower turn-around portion 144).In respective magnet assemblies 60,74,82,90,98 and 106, LC part 138 flows between left strip external magnet string and strip internal magnet string, and right core 140 flows between right strip external magnet string and strip internal magnet string.Upper turn-around portion 142 connects the upper end of LC part 138 and right core 140, and lower turn-around portion 144 connects the lower end of LC part 138 and right core 140.
Normally, the plasma density of turn-around portion 142,144 is different with the plasma density of core 138,140.This situation can cause the local erosion of target different.The phenomenon that target erosion during sputtering process is uneven.The measure of this phenomenon is avoided to be the magnetic field of weakening turn-around portion 142,144.Such as, described measure is reached by shunt (shunts) is applied to the magnet string in turn-around portion 142,144.Shunt is such as feeromagnetic metal sheet.This can reduce the target erosion of turn-around portion 142,144.But, turn-around portion 142,144 be the restriction of more weak local plasma compared with the side effect of low-intensity magnetic field, this can cause the electrical losses of peripheral part of the magnet assemblies of negative electrode and negative electrode.Especially, before the electronics of electron drift electric current reenters core 138,140, electrical losses is serious in the end of turn-around portion 142,144.
According to some embodiments, two or more negative electrodes with magnet assemblies are arranged close to each other, and interact with each other to make two adjacent negative electrodes.These negative electrodes form cathode array.But the adjacency between two negative electrodes can cause following impact: the adjacent magnet assemblies of neighbouring cathode may collect some electrical losses.The electronics of the electron drift electric current out of the ordinary of magnet assemblies flows to adjacent magnet assemblies in the end of turn-around portion from a magnet assemblies.This situation can cause between adjacent magnet assemblies and cross-talk occurs.Electronics jumps to the position of adjacent magnet assemblies and direction particularly depending on electron drift sense of current out of the ordinary from a magnet assemblies.And independent electron drift sense of current is the polar configurations of internal magnet string depending on respective magnet assemblies and external magnet string.Therefore, according to embodiment described herein, avoid, between the multiple negative electrodes in cathode array, most negative electrode or all negative electrodes, cross-talk occurs.This is because it is directed to have magnet alternately between the magnet assemblies of the negative electrode of at least two vicinities.
For embodiments more described herein, the effect that electronics jumps to adjacent magnet assemblies from a magnet assemblies is shown at Fig. 4.According to embodiment described in conjunction with Figure 4, the direction of the electron drift electric current 126 of magnet assemblies 60 is counterclockwise.Therefore, can occur in the end of the lower turn-around portion 144 of magnet assemblies 60 from electron drift electric current 126 to the Spectrametry of Electron Exchange (i.e. electronic crosstalk) of the electron drift electric current 128 of adjacent magnet assemblies 74.This cross-talk is indicated by arrow 146.The direction of the electron drift electric current 128 of magnet assemblies 74 is clockwise direction.Therefore, can occur in the end of the lower turn-around portion 144 of magnet assemblies 74 from electron drift electric current 128 to the Spectrametry of Electron Exchange of the electron drift electric current 126 of adjacent magnet assemblies 60.This cross-talk is indicated by arrow 148.In general, cross-talk 146 and cross-talk 148 are reverse each other, so that the described electrical losses of compensate for electronic drift current 126 and electron drift electric current 128.Further, can occur in the end of the upper turn-around portion 142 of magnet assemblies 74 from electron drift electric current 128 to the Spectrametry of Electron Exchange of the electron drift electric current 130 of adjacent magnet assemblies 82.This cross-talk is indicated by arrow 150.In next magnet assemblies 82, the direction of electron drift electric current 130 is counterclockwise once again.Can occur in the end of the upper turn-around portion 142 of magnet assemblies 82 from electron drift electric current 130 to the Spectrametry of Electron Exchange of the electron drift electric current 128 of adjacent magnet assemblies 74.This cross-talk is indicated by arrow 152.Because cross-talk 150 and cross-talk 152 are reverse each other, so at least by the electrical losses of near-earth compensate for electronic drift current 128 and electron drift electric current 130.Can occur in the end of the lower turn-around portion 144 of magnet assemblies 82 from electron drift electric current 130 to the Spectrametry of Electron Exchange of the electron drift electric current 132 of adjacent magnet assemblies 90.This cross-talk is indicated by arrow 154.In magnet assemblies 90, the direction of electron drift electric current 132 is clockwise direction once again.Can occur in the end of the lower turn-around portion 144 of magnet assemblies 90 from electron drift electric current 132 to the Spectrametry of Electron Exchange of the electron drift electric current 130 of adjacent magnet assemblies 82.This cross-talk is indicated by arrow 156.Because cross-talk 154 and cross-talk 156 are reverse each other, so at least by the electrical losses of near-earth compensate for electronic drift current 130 and electron drift electric current 132.Further, can occur in the end of the upper turn-around portion 142 of magnet assemblies 90 from electron drift electric current 132 to the Spectrametry of Electron Exchange of the electron drift electric current 134 of adjacent magnet assemblies 98.This cross-talk is indicated by arrow 158.In magnet assemblies 98, the direction of electron drift electric current 134 is counterclockwise.Can occur in the end of the upper turn-around portion 142 of magnet assemblies 98 from electron drift electric current 134 to the Spectrametry of Electron Exchange of the electron drift electric current 132 of adjacent magnet assemblies 90.This cross-talk is indicated by arrow 160.Because cross-talk 158 and cross-talk 160 are reverse each other, so at least by the described electrical losses of near-earth compensate for electronic drift current 132 and electron drift electric current 134.Can occur in the end of the lower turn-around portion 144 of magnet assemblies 98 from electron drift electric current 134 to the Spectrametry of Electron Exchange of the electron drift electric current 136 of adjacent magnet assemblies 106.This cross-talk is indicated by arrow 162.In magnet assemblies 106, the direction of electron drift electric current 136 is clockwise direction.Can occur in the end of the lower turn-around portion 144 of magnet assemblies 106 from electron drift electric current 136 to the Spectrametry of Electron Exchange of the electron drift electric current 134 of adjacent magnet assemblies 98.This cross-talk is indicated by arrow 164.Because cross-talk 162 and cross-talk 164 are reverse each other, so at least by the described electrical losses of near-earth compensate for electronic drift current 134 and electron drift electric current 136.
The compensation alternately caused electrical losses of the magnetic polarity between magnet assemblies is clearly illustrated at least nearly according to the embodiment of Fig. 4.The magnetic polarity that this kind replaces makes the electron drift sense of current between magnet assemblies reverse.This situation causes the position of electrical losses to be displaced to opposite side from the side of turn-around portion, namely from the supreme turn-around portion 142 of lower turn-around portion 144 and vice versa.
Advantageously, according to the present invention, the cross-talk (i.e. electrical losses) between neighbouring cathode can be avoided.This cross-talk may be by array electronic drift current through or array around contiguous negative electrode produced, described array has similar magnet assemblies.Outer cathode along cathode array flows by array electronic drift current, and jumps between negative electrode in the turn-around portion of magnet assemblies.Array electronic drift current can superpose the independent electron drift electric current in negative electrode.Due to array electronic drift current, in cathode array, the plasma density of the turn-around portion of the magnet assemblies of main inner cathode can increase.This can cause the increase of local target erosion, particularly at the target location of the turn-around portion close to magnet assemblies.Therefore, according to advantage of the present invention, uniform target erosion can be reached, the even erosion of the target of the inner cathode particularly in the array of the negative electrode by multiple vicinity.Therefore, the generation of array electronic drift current is avoided.
