Definitions
- the present invention relates to a Method and Apparatus for Electrochemical Mechanical Deposition, and more particularly, to a method and apparatus that provides for both the deposition and polishing of a conductive material on a semiconductor wafer.
- Metallization of semiconductor wafers i.e. deposition of a layer of metal on the face of wafers over a barrier/seed layer of metal has important and broad application in the semiconductor industry.
- aluminum and other metals are deposited as one of many metal layers that make up a semiconductor chip.
- copper reduces electrical resistance and allows semiconductor chips using copper to run faster with less heat generation, resulting in a significant gam m chip capacity and efficiency
- Conformal thm film deposition of copper into deep submicron via holes and trenches is becoming more difficult m ULSI chip processing, especially when the feature sizes are decreasing below the 0.25 ⁇ m with aspect ratios of greater than 5 to 1.
- Common chemical vapor deposition and electroplating techniques have been used to fill these deep cavities etched into silicon substrates. These processes so far have yielded a very high cost and defect density for developing and integrating local interconnects for ULSI technology.
- the cost of achieving the desired structure, m which the conductive mate ⁇ al exists m the via but not on the substrate surface still requires separate deposition and polishing steps
- a polishing step which polishing step is, for high performance devices at the present time, typically a chemical-mechanical polishing step While chemical mechanical polishing achieves the desired result, it achieves it at considerable expense, and requires a great degree of precision m applying a slurry in order to achieve the desired high degree of polish on the conductive surface.
- a conductive mate ⁇ al from an electrolyte solution to a predetermined area of a wafer.
- the steps that are used when making this application include applying the conductive mate ⁇ al to the predetermined area of the wafer using an electrolyte solution disposed on a surface of the wafer, when the wafer is disposed m proximity to an anode, and preventing accumulation of the conductive mate ⁇ al to areas other than the predetermined area by mechanically polishing, protecting, or reducing from electrolyte contact to the other areas while the conductive material is being deposited.
- An apparatus that performs this method includes an anode capable of receiving a first potential upon application of power.
- a cathode or the wafer is spaced from the anode and is capable of receiving a second potential opposite the first potential upon application of power
- a pad or a multiple number of pads is/are disposed between the anode and the cathode, the pad being movable with respect to a surface of the wafer and inhibiting or reducing application of the conductive mate ⁇ al to certain other areas when power is being supplied to the anode and the cathode
- a fluid chamber allows an electrolyte solution to be disposed on the surface of the wafer or the pad and the conductive material to be formed on desired areas of the wafer upon application of power.
- Fig. 2 illustrates a second embodiment of the invention
- Fig. 3 illustrates a representative via to be filled with a conductor according to the invention
- Figs. 4A - 4C illustrate a third embodiment of the invention. Detailed Description of the Preferred Embodiments
- the present invention contemplates different embodiments which allow for the same device, termed a "electrochemical mechanical deposition apparatus", to be used to both deposit a conductive mate ⁇ al, as well as then polish or reduce the rate of deposition of that conductive mate ⁇ al.
- the "electrochemical mechanical deposition apparatus” can also be used to simultaneously deposit and/or polish the conductive mate ⁇ al.
- the present invention can be used with any conductive matenal or any workpiece suitable for plating, it is especially suited for use with copper as the conductor, and for use m the fab ⁇ cation of ULSI integrated circuits having submicron features with large aspect ratios.
- the present invention uses conventional components, arranged in a unique manner, in order to achieve the functionalities described herein.
- Figure 3 is first referred to in order to illustrate a portion of an integrated circuit chip that includes an area in which a via is to be formed.
- the via as known m the semiconductor arts, being a conductive material that electrically connects different circuit layers together.
- a via contains a conductor 2 that can connect a lower level conductive area 4 with an upper level conductive area 6, with msulative material 8 disposed therearound.
- the present invention can operate upon any metal layer of a multi-layer integrated circuit chip.
- Figs. 1A and IB illustrate a first embodiment of the invention, which embodiment has two different modes of operation.
- a conductive metal preferably copper, or other conductive mate ⁇ al
- an electrolyte solution is applied in vias and/or other desired areas using an electrolyte solution, while build-up of the conductive material on undesired areas is eliminated, or at least minimized, due to the mechanical polishing and/or electrolytic solution deprivation to top surface areas of the semiconductor wafer that is desc ⁇ bed hereinafter.
- polishing of the wafer using a conventional chemical mechanical polishing, can be performed using the same device, to the extent that such chemical mechanical polishing is needed. It is contemplated that, according to this embodiment of the invention, m most circumstances only the first mode of operation will be needed. The second mode of operation and the structure corresponding thereto are included for circumstances in which an extremely high degree of polish is desired.
- Fig. 1A illustrates an overview of the electrochemical mechanical deposition apparatus 10 according to the first embodiment of the invention, illustrating in perspective view the mechanical pad assembly 12 that has a mechanical pad 32 that rotates around a first axis 14, and a wafer head assembly 16 that has a wafer that rotates around a second axis 18. As illustrated, the wafer rotates within an area that is covered by the mechanical pad 32, as will be described in further detail hereinafter, which area is within container 20 that keeps various solutions disposed therein. Although shown as operating upon a single wafer, it is understood that a plurality of wafer head assemblies 16 could be associated with each mechanical pad assembly 12, and that the apparatus 10 could include a plurality of mechanical pad assemblies 12 as well, each operating on different wafers.
- Fig. IB illustrates a side cross sectional view of the apparatus 10 taken along line A-A of Fig. 1A according to the present invention.
- the system 10 is capable of depositing thin metal films onto the wafer.
- Each wafer head assembly 16 includes a nonconductive, preferably circular, head assembly 22 with a cavity that is preferably a few millimeters deep at its center and which cavity may contain a resting pad 25.
- the semiconductor wafer is loaded into this cavity 22, backside first, against the resting pad 25 using a conventional type of transport or vacuum mechanism to ensure that the wafer is stationary with respect to the wafer head assembly while in use.
- a nonconductive retaining ring 24 at the periphery of the wafer head assembly 10 includes at least one O-ring or other rubber type seal 26 and a spring loaded cathode contact electrode 28, which each push against the face of the wafer and hold the wafer in place at its very edge. A liquid-tight seal is thus obtained so that the cathode contact electrode 28 is kept isolated from the solution within the container 20, as described hereinafter.
- the entire back side of the wafer which pushes against resting pad 25 and the front surface areas (typically the outer 1-10mm surface of the front surface area) which are under this retaining ring 24 will thus be protected from any and all solutions, including electrolyte, as discussed hereinafter.
- the mechanical pad assembly 12 is disposed within container 20, which container 20 holds the various solutions that will be introduced, as described previously and hereinafter.
- Mechanical pad assembly 12 includes an anode plate 30 that preferably has a thin flat circular shape and is made of a porous or solid conductive material such as copper and/or platinum and is mounted so that it rotates about the second axis 18, and rests upon a table and bearing support as is known.
- a mechanical pad 32 as is known in the art and used, as example, in chemical mechanical polishing, and preferably one that is made of a nonconductive, porous type material such as polyurethane, is mounted onto the face of the anode plate 30.
- the mechanical pad 32 preferably has a circular shape, but may be shaped in any other form so long as it can effectively polish the wafer.
- the electrolyte can be fed to the pad 32 from a reservoir (not shown) located behind the anode plate 32 via a chamber 31 , which chamber 31 then feeds the electrolyte up through the anode plate 30 and pad 32 using the m-channel 34.
- m- channel 44 can also be used to dispense the electrolyte directly down onto the surface of the pad 32.
- the wafer head assembly 16 faces toward the mechanical pad assembly 12, and is pushed down with a controlled force
- the wafer head assembly 16 rotates around axis 18 using a conventional motorized spmdle 36, whereas the mechanical pad assembly 12 rotates around axis 14 using a conventional motorized spmdle 38.
- Proper drainage channels 40 provide a safe recycling or disposal of electrolyte.
- the electrolyte once placed onto the pad 32 as desc ⁇ bed above, it can be drained via the drainage channels 40 to a resuscitating reservoir, also not shown, that can replenish and clean the electrolyte, thereby allowing re-use and being environmentally safe.
- the mlet 44 can also be used to apply deionized water when operating in the second mode of the invention, as discussed hereinafter.
- the apparatus 10 applies, using a power source, a negative potential to the cathode contact 28 and a positive potential to the anode 30.
- the electrolytic solution is introduced through one or both of the m-channels 34 and 44 to the surface of the mechanical polishing pad 32.
- molecules of metals in electrolyte are ionized and deposited on the surface of the wafer, being attracted thereto by the cathode contact 28. While this is taking place, there is also performed a mechanical polishing using the mechanical pad assembly 12.
- This mechanical pad assembly 12 substantially prevents molecules of metals from becoming permanently deposited on surfaces of the wafer where such a deposit is undesired, due to the polishing or rubbing action of the mechanical pad 32.
- the contaminants or additives referred to above that are presently used to prevent or reduce such depositing are not needed, or alternatively, can be used m much smaller percentages Accordingly, at the conclusion of the first mode of operation, metal is deposited m vias and the like where desired, and is substantially prevented from being deposited in undesired areas.
- a number of different conventional operations can be performed, depending upon the chemicals introduced via the m-channel 44 If chemical mechanical polishing is desired, a slurry can be introduced, although this specific mode of operation is not preferred since it increases the amount of impu ⁇ ties introduced into the apparatus fluid chamber substantially.
- the apparatus 10 can be used to buff polish the seed layer or be used as an Electro-polisher by reversing the current polarity (cathode and anode polarity) Further, the apparatus 10 can also be purged with M water if it is necessary to leave the wafer clean but wet with deionized water, and polishing using the mechanical pad 32 with the deionized water can take place Thereafter, after lifting the wafer off the pad 32, spin drying of the wafer on the rotating wafer head assembly 12 can take place.
- Fig. 2 illustrates another embodiment of the invention. Like reference numerals are used to indicate structure that corresponds to that of Figs. 1A and IB described above.
- the wafer is stationery, and electrochemical mechanical deposition apparatus 100 is disposed within a container (not shown) that collects spent solutions.
- the electrochemical mechanical deposition apparatus 100 corresponds m structure in large part to the wafer head assembly 16 previously described with reference to Fig. IB.
- the electrochemical mechanical deposition apparatus 100 includes a mechanical pad 32, which is rotated by the spmdle shaft 36.
- Spmdle shaft 36 is illustrated as being rotated and moved side to side and held in proper position using DC motor 102.
- weights 104, bearing sets 106 and 108 and sp ⁇ ngs 110 all of which are conventional
- the electrolyte solution is introduced using in passage 34, and it flows to the desired surface of the wafer through the porous anode 30 and mechanical pad 32. It is expelled through out-channel 40.
- Fig. 2 embodiment Operation of the Fig. 2 embodiment is very similar to that of the first mode described with respect to Figs. 1A and IB. Specifically, deposition of a conductive material using an electrolyte, such as desc ⁇ bed previously, m desired vias and/or other areas, is obtained at the same time that mechanical polishing of the surface of the wafer using rotating pad 32, which may be the shape of a rectangle, a circle, or a pie or the like, takes place.
- an electrolyte such as desc ⁇ bed previously, m desired vias and/or other areas
- the electrochemical mechanical deposition apparatus also reduces the need for pulse generating power supplies because the mechanical pulsing that is generated from the movement of the pad creates sufficient pulsing. This mechanical pulsing is created as a result of the wafer being in contact with the pad as it is moved m relation to the wafer. The benefit of the mechanical pulsing is that it improves gram size and copper film integrity without the need for power supplies with pulsing capabilities.
- Figs. 4A-4C illustrate yet another preferred embodiment of the present invention.
- the electrochemical mechanical deposition apparatus 200 contains a mechanical pad assembly 210 that corresponds to the mechanical pad assembly 12 and a wafer head assembly 240 that corresponds to the wafer head assembly 16.
- the electrochemical mechanical deposition apparatus 200 includes a circular or square mechanical pad 212 mounted on a cylindrical anode 214 that rotates about a first axis 216 as illustrated m Figs. 4A and 4C, whereas the wafer rotates about a second axis 242 as illustrated in Fig. 4B.
- the mechanical pad 212 can have a size that either polishes the entire useable portion of the wafer, or only a section of the wafer at any given time. If only a portion of the wafer is polished at any given time, a drive assembly (not shown) must also be included in order to move the anode 214, and thereby the mechanical pad 212, so that it is in contact with the portion of the wafer that needs to be acted upon at that moment m time. In operation, it will be appreciated that the belt-shaped mechanical pad 212 polishes the wafer similar to the manner m which a roller paintbrush paints a wall.
- the electrolyte or other solution is introduced to the mechanical pad 212 from a reservoir (not shown) located in proximity to the anode 214
- the anode 214 contains an m-channel 224 that includes a passageway 226 within anode 214 and holes 228 that are made in the anode 214, which together provide a path for the solution to be fed to the mechanical pad 212.
- the electrolyte solution can be dispensed directly onto the pad 212 through a channel 213 m accordance with the methods described earlier herein.
- the solution will be contained withm a non-conductive chamber 230 that is created around the wafer head assembly 240, and a non-conductive solution containment housing 250, which housing contains an out-channel 252. O- ⁇ ngs and other conventional structures, as described earlier herein, to seal the solution withm the solution containment housing 250 may be used in this embodiment
- the electrochemical mechanical deposition apparatus reduces the need for pulse generating power supplies because the mechanical pulsing that is generated from the rotating movement of the pad and wafer creates sufficient pulsing.
