Description
Technical field
The present invention relates to a kind of can be with the cambial plasma damage free sputter gun of high speed, a kind of sputter equipment that comprises described sputter gun, a kind of plasma processing apparatus that utilizes described sputter gun, and a kind of next cambial method of described sputter gun of utilizing, more specifically, relate to a kind of plasma damage free sputter gun, wherein, in the center of sputter gun with a plurality of magnets of ladder arranged in form, and be different from conventional to target sputter gun (Facing Target Sputter Gun), with this plasma density that increases the sputter gun middle part, making can be with the high speed cambium layer in plasma damage free sputter technology; Relate to a kind of sputter equipment of described sputter gun, a kind of plasma processing apparatus and a kind of next cambial method of described sputter gun of utilizing of utilizing described sputter gun of comprising.
Background technology
In general, the manufacturing of organic electro-optic device or organic transistor comprises the formation metal electrode layer.As known to, sputtering technology is to form at a high speed the typical method of thin metal layer.Sputtering technology is widely used in and forms the thin metal layer that uses in flat-panel display device (FPD) and various electronic device, and described flat-panel display device is thin film transistor LCD device (TFT LCD) and organic light emitting diode device (OLED) for example.
In sputter equipment, in the vacuum of sputtering chamber, produce plasma.The plasma cation is with the negative potential attracts of the negative electrode of target.Plasma cation collision target and be split into little particle and particle is deposited on the substrate.
The plasma cation splits into little particle and is called as sputter.In the situation of non-reacted sputtering technology, plasma is made of inert gas, for example argon Ar.In the situation of reactive sputtering technology, plasma is the plasma with oxygen O2, or has the plasma of the mixture of oxygen O2 and inert gas.
In order to improve the effect of sputter, using magnet near the target so that plasma remains on the target with magnetic field.The introduction by magnetic field plasma electron enters particular path.Plasma electron makes neutral gas (as argon Ar) ionization and produces cation on particular path.Cation is bigger than electron mass, and is therefore not affected by magnetic fields fully.Yet cation has dropped on the target of cathodic process and sputtering target.The ionization of neutral gas occurs in magnetic vector substantially and extends to the position that is parallel to the target surface.Because plasma is the most intensive on this position, therefore target consumes at most on this position.
That is to say that sputtering technology comprises and produces plasma and the Ar ion of plasma is collided to sputter composite material (layer forming material) with target.Yet the particle that contains in the plasma has high energy, and the particle that sputters also has high energy.Therefore, when having the particle encounter substrate of high energy, energy is sent to substrate, makes substrate can be heated to up to about 200 ℃ temperature, and then sustains damage.
And when having 100eV or more high-octane particle encounter organic thin layer, the structure of organic thin layer, optics and electric property may be subjected to bad influence.Particularly, when utilizing sputtering technology on organic thin layer, to form metal level such as Al layer, Mg-Ag layer or Ag layer to form the negative electrode of OLED, the hole injection layer, hole-transporting layer and the emission layer collision that are made of organic material have the plasma particle of high energy, thereby degenerate to some extent on electric and optical characteristics.
In order to overcome these problems, proposed a kind ofly recently to the target sputtering technology, therefore might in the manufacturing of OLED device, adopt sputtering technology.
Figure 1A to Fig. 1 C shows conventional rectangle to the magnet arrangement method of target sputter gun and the schematic diagram of flux density distribution.
Conventional is to make by the hollow magnet of arranging annular or rectangle to the target sputter gun.Yoke plate (Yoke Plate) is attached to the top side of hollow magnet and bottom side to make the magnetic field uniformization of hollow magnet haply.Like this, the magnetic flux of hollow magnet can be homogenized, but the flux density at magnet middle part reduces, thereby reduced plasma intensity.
And, can find out that from Figure 1A to Fig. 1 C because magnet arrangement is in the periphery of target, the periphery of sputter gun has high flux density and the middle part of sputter gun has small throughput density, has therefore reduced a layer deposition rate.Although charged particle can be fettered because of the magnetic flux that is connected between a sputter gun and another sputter gun, because of the small throughput density in the middle part of the sputter gun can not be to form thin layer at a high speed.
Therefore, need a kind of new plasma damage free sputter gun of development, described plasma damage free sputter gun increases the flux density at sputter gun middle part to improve the plasma particle that layer deposition rate and constraint have high energy.

Fig. 2 A and Fig. 2 B are the schematic diagrames of the magnetic system 1 that moves on target 2, and it is disclosed among the open No.2005-0082411 of Korean Patent.
Magnetic system 1 comprises the peripheral magnet 3 and the bar shaped internal magnets 4 of frame shape.The peripheral magnet 3 of frame shape comprises two strip magnets 5 and 6 and two billet shape magnets 7 and 8.Billet shape magnet 7 and 8 and strip magnet 5 and 6 at right angles arrange.For example, bar-shaped magnet 5,6,7 and 8 is a S utmost point magnet, and internal magnets 4 is a N utmost point magnet.The magnetic field of extending on the side surface of magnetic system 1 is bent to form parabola, and described parabola passes target 2 from peripheral magnet 3, and extends to internal magnets 4.Because described magnetic field, electrode is easy to form plasmatron 9, and the positive electricity particle in the plasmatron 9 (for example Ar ion) quickens to arrive target 2.Plasmatron 9 comprises vertical area 16 and 17 and horizontal zone 18 and 19.
The Ar ion makes the sightless rear section corresponding to plasmatron 9 of target 2 be cleaved into particle, makes to have formed the sunk part that has corresponding to the shape of plasmatron 9 in target 2.When magnetic system 1 moved to the right side with the direction of arrow 10 on fixing target 2, the aft section of target 2 was etched except that its outward flange in an identical manner.
Fig. 2 B is the profile along the line I-I intercepting of Fig. 2 A.Referring to Fig. 2 B, magnetic field 30 and 31 is passed target 2 and is formed parabola.The substrate 20 of particle that is coated with the division of target 2 places under the target 2.Be in the space between target 2 and the substrate 20 near the unit that makes target 2 place to be formed in the above described manner the magnetic system 1 the particle division that makes target 2 by cation quicken being surpassed plasma that the anion (not shown) produces.Whole device shown in Fig. 2 A and the 2B places vacuum film coating chamber 29.
Yet, in above-mentioned conventional sputter equipment, be difficult to control plasma density and layer deposition rate.
