Description

Fluid region control device and working method thereof
Technical field
The present invention relates to a kind of fluid region control device and working method thereof, relate in particular to a kind of fluid region control device and working method thereof that can be applicable to electroplate (plating) technology, cleaning (cleaning) technology or glossing.
Background technology
At present, include physical vapor deposition, chemical vapour deposition, wireless plating technology, reach electrochemical plating etc. in order to the technology that forms metal material layer.Wherein, (electro chemical plating, ECP) technology has the advantage that cost is cheap and output capacity is fast, is widely used in the industry member because electrochemistry is electroplated.In electroplating process, the plated film quality can be subjected to the influence of cleanliness factor or the like factor on composition, temperature, current density and the plated body surface of plating bath.
See also Fig. 1 to Fig. 3, Fig. 1 to Fig. 3 is the process schematic representation of known electric chemical plating process.As shown in Figure 1, at first provide a wafer 10 and an electroplanting device 20.Electroplanting device 20 includes a plating tank 12, and electroplates fluid 22, anode system (anode system) 14, one cathode electrode (cathodeelectrode) 16 and a fixation kit (fixing component) 18.Plating tank 12 is electroplated fluid 22 in order to splendid attire, and the main component of plating fluid 22 is for containing metal ion solution.Anode system 14 includes an anolyte compartment (anode chamber) 30, one anode electrode 24, a filtration membrane (filtermembrane) 26, a diffusion film (diffuser membrane) 28 and is electroplated fluid provides pipeline 32.
Wafer 10 is positioned between cathode electrode 16 and the fixation kit 18, wafer 10 is clamped by cathode electrode 16 and fixation kit 18.Then, as shown in Figure 2, slightly inclined wafer 10 makes wafer 10 and electroplates between the liquid level of fluid 22 to have after the angle, again with wafer 10 slowly in the immersion plating fluid 22, makes relatively to be difficult for entrained air bubbles on the surface of wafer 10.Thereafter, as shown in Figure 3, cathode electrode 16 is electrically connected on the galvanized wafer 10 of desire, and in order to promote the homogeneity of coating film thickness, generally cathode electrode 16 all can rotate when electroplating, and can continue to touch fresh plating fluid to guarantee wafer 10.When this electroplanting device 20 was bestowed external voltage or electric current, the circuit of being made up of anode system 14, plating fluid 22, cathode electrode 16 just can be switched on, and carries out reduction reaction around cathode electrode 16, and metallic substance is plated on the wafer 10.
The known electric chemical plating process not only can be plated in metallic substance on the crystal face of wafer 10, also can metallic substance be plated on the crystal edge of wafer 10 simultaneously.Yet in fact the metallic substance that is attached to edge bevel surface is not that product is required.The phenomenon follow-up when carrying out other semiconductor technology, that the metallic substance of edge bevel surface peels off (peeling) through regular meeting because be subjected to thermal stresses (thermal stress) or other factors, and then cause metallic substance cracked and produce chip or particle.Especially ought be positioned over chemical vapour deposition (chemical vapor deposition by semi-conductor chip by the gross, when CVD) carrying out CVD technology in the device, this phenomenon of peeling off if take place in the wafer 10 of relative top, position, will other positions of severe contamination wafer 10 surfaces of below relatively, cause defective.In addition, in response to the required and mobile wafer 10 of technology the time, the chip of this metallic substance also tends to fall on the surface of wafer 10 and polluted product, and then influences the function (performance) of product.
For fear of above-mentioned defective, need carry out extra removing technology, cleaning and drying process in addition after the known electric chemical plating process, be attached to the metallic substance of edge bevel surface with removal.This not only can increase process time and technology cost, also can increase the complexity of technology, and then may cause the yield of product to descend.At electroplating fluid 22, because known anode system 14, wafer 10 need whole soaking to place plating fluid 22 with cathode electrode 16, and wafer 10 must favour the liquid level of electroplating fluid 22 and immerse, so the known electric chemical plating process needs huge plating tank 12 and a large amount of plating fluids 22.After the electrochemistry electroplating technology carried out for some time, technology just needed to suspend, to pour out old plating fluid 22 and to inject new plating fluid 22.Thus, the replacing of electroplating fluid 22 can expend the tediously long time again, makes output reduce.
On the other hand, in order to carry out the known electric chemical plating process, single wafer 10 must be placed between cathode electrode 16 and the fixation kit 18 by mechanical arm earlier, then insert obliquely and electroplate in the fluid 22, open electroplanting device 20 and carry out electroplating reaction thereafter, shift out plating tank 12 again, and carry out cleaning and drying process or the like subsequent technique.Hence one can see that, is subjected to electroplanting device 20 operational restrictions, and the known electric chemical plating process can't a large amount of wafer 10 of batch processed, and then badly influence the output of product.Moreover known electroplanting device 20 is difficult to that wafer 10 is carried out instant (in-situ) and measures, and therefore not only makes known technology can't control the electrochemistry electroplating technology accurately and quickly, and the step of measurement also can expend the extra time.

Under aforesaid situation, to control fluid 154 and can not react each other with plating fluid 156, control fluid 154 is to utilize itself and plating fluid 156 immiscible characteristics to limit to the position and the shape of electroplating fluid 156.In the present invention, process fluid all can be liquid state, gaseous phase, steam condition (vapor state) or colloidal state (gel state) with the control fluid.For example, electroplating fluid 156 is to flow with liquid state, and control fluid 154 then is to flow with gaseous phase.Or electroplating fluid 156 can be liquid state with control fluid 154 simultaneously.Even control fluid 154 can include a supercutical fluid, for example carbonic acid gas.In other embodiments of the invention, control fluid 154 can also include other various materials and comes the operation of auxiliary process or subcontrol to electroplate flowing of fluid 156.For instance, control fluid 154 can include an ionized gas (ionizedgas), a hot gas or a cold air, to change technological temperature or the temperature and the characteristic of electroplating fluid 156.Thus, shape and position that control fluid 154 can be kept process fluid on the one hand on the other hand can reinforcing process, even can also remove residual residue at the semiconductor-based end 110.
One of principal character of the present invention is to utilize a control fluid to replace known container, the space that occupies with CONTROL PROCESS required fluidic position and process fluid.In order to achieve the above object, control fluid and process fluid are immiscible each other, then controlling fluid can limit to the space that process fluid occupies, the space that utilizes control fluid and process fluid magneticaction each other to come the CONTROL PROCESS fluid to occupy by the mobile moving-wire P that flows own, or utilizes and control fluid and process fluid electric power each other and be used for the space that the CONTROL PROCESS fluid occupies.In view of this, control fluid 154 can include material with magnetic, has electrical material, magnetic flow liquid (magneto-rheological fluid, MRF), electrorheological fluid (electro-rheological fluid, ERF), or even solia particle.Thus, fluid region control device 220 can utilize the characteristic of magnetic force (magnetic force) or electric power (electric force) control fluid 154 or plating fluid 156, and then flowing of fluid 156 electroplated in control.
The aforementioned operation method only is wherein a kind of embodiment of the present invention, and control fluid 154 can be adjusted according to the actual process demand with the actual flow mode of electroplating fluid 156.In other words, at different process requirements, control fluid 154 of the present invention or plating fluid 156 can be flowed out by any pipeline, and reclaim in suitable pipeline.See also Figure 15 to Figure 18, what it illustrated is the synoptic diagram that is used for other working method of galvanized fluid region control device 220 shown in Figure 13, and wherein components identical or position are still continued to use identical symbol and represented.Figure 15 can be applicable to an electrochemistry electroplating technology equally to working method shown in Figure 180, and the main difference part of these working method and aforementioned operation method is that control fluid 154 changes to some extent with the flowline of electroplating fluid 156.
As shown in figure 15, control fluid 154 is to flow out from the 4th pipeline 144 equally, and reclaims by the 3rd pipeline 142.Change by 134 outflows of second pipeline but electroplate fluid 156, and reclaim by first pipeline 132.As shown in figure 16, the mobile moving-wire P of control fluid 154 is constant equally, is preferably flowed out by the 5th pipeline 136 but electroplate fluid 156, and reclaims with second pipeline 134 by first pipeline 132.As shown in figure 17, electroplate fluid 156 and flow out, and reclaim by second pipeline 134 by first pipeline 132.And control fluid 154 is flowed out by the 6th pipeline 146, and reclaims by the 3rd pipeline 142.Or shown in Figure 180, electroplate fluid 156 and flow out, and reclaim by second pipeline 134 by first pipeline 132.And control fluid 154 is flowed out with the 7th pipeline 148 by the 6th pipeline 146, and reclaims by the 3rd pipeline 142 and the 4th pipeline 144.
What pay special attention to is, aforesaid fluid region control device 220, fluid flow moving-wire P and process fluid flow moving-wire all can be applicable in a solvent cleaning (solvent cleaning) technology, and fluid region control device 220 of the present invention can be applicable to any needs in the red-tape operati fluidic technology, for example a drying process, a wet etch process, an electroless-plating (electroless plating) technology, a chemically machinery polished (chemical mechanical polishing, CMP) technology, or an electrochemical mechanical polishing technology or the like.When fluid region control device 220 is applied to cleaning, anode electrode 124 need not be electrically connected to different potentials with cathode electrode 116, and electroplating fluid 156 replaceable is washing fluid, for example a deionized water (deionized water, DI water) or a supercutical fluid.Therefore, semiconductor substrate 110 is accepted after the electrochemistry electroplating technology in fluid region control device 220, can close the voltage that puts on anode electrode and cathode electrode, and change process fluid, soon in same device, accept a cleaning or a drying process.
Hence one can see that, when being applied to cleaning, and fluid region control device even can not need anode electrode and two assemblies of cathode electrode.See also Figure 19, it illustrates is the diagrammatic cross-section of the second preferred embodiment of the present invention fluid region control device 320 that is used to clean, and wherein components identical or position are continued to use identical symbol and represented.As shown in figure 19, present embodiment provides a kind of fluid region control device that is used to clean 320.Fluid region control device 320 and fluid region control device 220 main differences are that the fluid region control device 320 that is used to clean can not need cathode electrode 116 and anode system 114.Therefore, fluid region control device 220 can utilize a fixation kit 216 to fix the semiconductor-based end 110, and utilize a pipeline system (tube system) 214 to assist the reaction height H of CONTROL PROCESS, wherein fixation kit 216 can be electrostatic chuck, vacuum pad or forceps type structure.Pipeline system 214 is positioned at substrate bearing base 130 tops, be provided with corresponding to the semiconductor-based end 110 in essence, and with substrate bearing base 130 at a distance of a reaction height H.Definition has a pending zone (not being shown among the figure) and a non-treatment zone (not being shown among the figure) on the substrate bearing base 130.Part is positioned at the predetermined processing that will accept technology in the semiconductor-based ends 110 in pending zone, and part is positioned at the predetermined processing of not accepting technology in the semiconductor-based ends 110 of non-treatment zone.
In addition, in another embodiment of the present invention, fluid mass Controlling System 120 itself just can be used for cleaning, etch process or drying process, and utilizes the gravity of process fluid itself and the position that the control fluid is kept process fluid, as shown in figure 20.
When fluid region control device 320 was applied to etch process or cleaning, control fluid and process fluid can also have other flow pattern.See also Figure 21 to Figure 24, what it illustrated is the synoptic diagram of other working method of the fluid region control device that is used to clean 320 shown in Figure 19, wherein components identical or position are still continued to use identical symbol and are represented, and the semiconductor-based end 110 herein can be a wafer equally.As shown in figure 21, in the time will cleaning the crystal face at the semiconductor-based end 110, first pipeline 132 provides the required washing fluid of technology 256 with second pipeline 134, and reclaims washing fluid 256 by the 5th pipeline 136.And control fluid 154 is flowed out with the 7th pipeline 148 by the 6th pipeline 146, and reclaims through the 3rd pipeline 142 and the 4th pipeline 144 from lower to upper.Perhaps also can be as shown in Figure 22, control fluid 154 is flowed out with the 4th pipeline 144 by the 3rd pipeline 142, and reclaims through the 6th pipeline 146 and the 7th pipeline 148 from top to bottom.
In the time will cleaning the crystal edge at the semiconductor-based end 110, the pending zone of fluid region control device 320 can correspond to the crystal edge at the semiconductor-based end 110, but not treatment zone can correspond to the crystal face at the semiconductor-based end 110.As shown in figure 23, first pipeline 132 provides technology required control fluid 154 with second pipeline 134, and reclaims control fluid 154 by the 5th pipeline 136, and the crystal face that is positioned at the wafer of non-treatment zone with protection does not contact with washing fluid 256.And washing fluid 256 is flowed out by the 6th pipeline 146, and reclaims through the 3rd pipeline 142.Moreover as shown in figure 24, when cleaning the brilliant unlucky of the semiconductor-based end 110, fixation kit 216 can slightly lift the semiconductor-based end 110 earlier, provides washing fluid 256, the three pipelines 142 to reclaim washing fluid 256 by the 6th pipeline 146.And control fluid 154 is flowed out by first pipeline 132 and second pipeline 134, and reclaims through the 5th pipeline 136.
The fluid region control device 320 that is used for galvanized fluid region control device 220 or is used to clean of the present invention also can be applicable to CMP (Chemical Mechanical Polishing) process, and wherein this technology can be divided into traditional chemical mechanical polishing process and electrochemical etching technology.Please refer to Figure 25, it illustrates is the diagrammatic cross-section of the 3rd preferred embodiment of the present invention fluid region control device 720 that is used to polish.As shown in figure 25, fluid region control device 720 can include a polishing system (polishing system) 714 and one fluid mass Controlling System 120, wherein polishing system 714 also includes a polishing pad (polishing pad) 751, one polishing pad permanent seat (pad holder) 724, and polishing slurries (slurry) 158.
When being applied to electrochemical etching technology, fixation kit 216 can be used as anode electrode, and polishing pad permanent seat 724 can be used as cathode electrode, quickens polishing efficiency in order to energising.In addition, when being applied to the traditional chemical mechanical polishing process, fluid region control device 720 can be closed the voltage that puts on anode electrode and cathode electrode, can carry out the traditional chemical mechanical polishing process in same device.In other words, replacing, switch by subelement, and the replacing of process fluid, various technology can be promptly carried out at the semiconductor-based end 110 in single fluid regional control device 720, for example soon accept a cleaning after a CMP (Chemical Mechanical Polishing) process.
Definition has a pending zone (not being shown among the figure) and a non-treatment zone (not being shown among the figure) on the substrate bearing base 130.Part is positioned at the predetermined processing that will accept CMP (Chemical Mechanical Polishing) process in the semiconductor-based ends 110 in pending zone, and part is positioned at the predetermined processing of not accepting CMP (Chemical Mechanical Polishing) process in the semiconductor-based ends 110 of non-treatment zone.What especially note is, aforesaid fluid flow moving-wire P and process fluid flow moving-wire all can be applicable in the CMP (Chemical Mechanical Polishing) process, and the height of polishing pad 751 and position all can be adjusted according to technology is required.When carrying out CMP (Chemical Mechanical Polishing) process, polishing pad 751 can apply pressure to downwards on the surface, the semiconductor-based ends 110, and perhaps substrate bearing base 130 or fixation kit 216 also can will be lifted to polishing pad 751 surfaces at semiconductor-based the end 110.
Polishing system 714 can also include a sensor 722 that can measure wafer Flatness or material layer thickness, measures semi-conductor substrate 110 each position are carried out an instant Flatness, and measurement can be fed back in the technology immediately.In addition, polishing system 714 can include various types of burnishing devices, for example one rotary (rotary type) burnishing device, a linearity (linear type) burnishing device, a rail mounted (orbital type) burnishing device, or a fixing polishing particulate (fixed abrasive web) system.For instance, when polishing system 714 is a fixing polishing microparticulate systems, polishing pad 751 itself can have various types of polishing particulates, and the process fluid that fluid region control device 720 is supplied can be a deionized water, polishing pad 751 with polishing particulate is cooperating deionized water to get final product the whole semiconductor-based end 110 of tumbling or the specific region at the semiconductor-based end 110, the bulge-structure of the material layer on surface, for example semiconductor-based ends 110.In the actually operating, the size of polishing pad 751 can be 110 bigger than the semiconductor-based end, littler than the semiconductor-based end 110, or the same big with the semiconductor-based end 110.
Also can know by inference thus, when the fluid region control device 320 that is used to clean was equiped with at least one polishing pad, fluid region control device 320 can carry out the traditional chemical mechanical polishing process.
Because fluid region control device 720 can utilize the control fluid to control the position of polishing slurries 158 or deionized water, and the whole semiconductor-based end 110 or the specific region at the semiconductor-based end 110 are polished in the height and the position of control polishing pad 751, so fluid region control device 720 has following advantage.At first, fluid region control device 720 can be adjusted the position of pending zone and non-treatment zone easily, also can adjust the relative position at the semiconductor-based end 110 easily, so can polish at the specific region at the semiconductor-based end 110, and needn't worry that the semiconductor-based end 110 or the material layer that are positioned at other zones are polished and loss or destruction.
Secondly, in traditional etch process, traditional depositing operation, or after traditional glossing, the single semiconductor-based end 110 or surface of a certain material layer tends to occur the not good problem of uniformity coefficient (uniformity) on it, for example after traditional glossing, the edge at the semiconductor-based end 110 can the center can be thicker than approaching.Because fluid region control device 720 can be adjusted the position of pending zone and non-treatment zone easily, also can measure the Flatness at the semiconductor-based end 110 or the thickness of material layer immediately, so the semiconductor-based end 110 or material layer that the energy automatic polishing goes out to have good uniformity coefficient.
Moreover, because fluid region control device 720 is to utilize the control fluid to control the position of required acceptance polishing, therefore fluid region control device 720 can have the polishing pad 751 of arbitrary dimension, usually must be greater than the size at the semiconductor-based end 110 unlike the polishing pad size of conventional polisher platform.In addition, because fluid region control device 720 can apply polishing slurries 158 or deionized water at pending zone, therefore can avoid polishing slurries 158 to touch the zone of other vulnerable to pollution at the semiconductor-based end 110, also can save the usage quantity of polishing slurries 158 or deionized water, avoid unnecessary cost loss.
Be noted that in addition the present invention is used for galvanized fluid region control device 220, fluid region control device 320 that is used to clean and the fluid region control device 720 that is used to polish can carry out art breading to the specific region of wafer.See also Figure 26, what Figure 26 illustrated is an operation chart of fluid region control device of the present invention.As shown in figure 26, fluid region control device can include a fluid mass Controlling System 120 and a system 914, and wherein system 914 can be anode system 114, pipeline system 214 or polishing system 714.Fluid region control device can carry out zonal electroplating technology, cleaning or glossing to semi-conductor substrate 110.The pending zone here need not be limited to crystal face and crystal edge, can correspond to the optional position at the semiconductor-based end 110, for example correspond to certain active region on the wafer, rest part at the semiconductor-based end 110 then can correspond to non-treatment zone, and for example non-treatment zone can correspond to certain neighboring area on the wafer.In other embodiments, pending zone can correspond to the crystal face of wafer, the brilliant back of the body, crystal edge, or any regional area that needs processing, and the rest part of wafer then can correspond to non-treatment zone.
In sum, because the present invention utilizes the control fluid to come CONTROL PROCESS fluidic position, therefore need huge plating tank and a large amount of plating fluids unlike the known electric chemical plating process.In addition, control fluid of the present invention and process fluid can cycling and reutilizations.After control fluid or process fluid reclaim through pipeline, can directly be back to and continue in the fluid region control device to utilize through another pipeline.Perhaps, the process fluid of recovery also can be supplied to and continue in the fluid region control device to utilize through after the instant processing or non-instant processing with the control fluid again.In other words, the present invention can according to the state that reclaims fluid or recovery process fluid and component proportions be added new fluid or process fluid is allocated, also can be to reclaiming fluid or reclaiming process fluid and carry out suitable separating step, then fluid or the process fluid that will handle again is supplied in the fluid region control device.Thus, the present invention can be easily and immediately adjusting process fluidic component proportions and state, makes technology maintain good situation, need not expend tediously long time and huge cost and remove to change process fluid, can also reduce the usage quantity of process fluid.In addition, the also visual process requirements of the present invention provides a heating unit to be arranged in the fluid control device, in order to heating the semiconductor-based end or process fluid, and then promotes the required temperature of reaction of technology or accelerates its speed of response.
On the other hand, fluid region control device of the present invention can make technology only act on the part that need accept art breading at semiconductor-based the end by the control of flow velocity and pipeline, and guarantee that simultaneously technology can not act on the part that need not accept art breading at semiconductor-based the end, therefore can avoid the electrochemistry electroplating technology to plate metal level in Waffer edge, that omits edge metal removes step (edge bevelremoval step, EBR step), and then save process time and technology cost, and reduce the complexity of technology.
