- Figure 1 is a top plan view of one embodiment of a chemical mechanical polishing system
- Figure 2 is a partial side view of a polishing station of Figure 1 according to one embodiment of the invention.
- Figure 3 is a flow chart of a method for simultaneously polishing multiple substrates that may be practiced in the one embodiment according to the invention.
- FIG. 1 is a top plan view illustrating one embodiment of a chemical mechanical polishing ("CMP") system 100.
- the CMP system 100 includes a factory interface 102, a cleaner 104 and a polishing module 106.
- a wet robot 108 is provided to transfer substrates 170 between the factory interface 102 and the polishing module 106.
- the wet robot 108 may also be configured to transfer substrates between the polishing module 106 and the cleaner 104.
- the factory interface 102 includes a dry robot 110 which is configured to transfer substrates 170 between one or more cassettes 114 and one or more transfer platforms 116.
- the dry robot 110 has sufficient range of motion to facilitate transfer between the four cassettes 114 and the one or more transfer platforms 116.
- the dry robot 110 may be mounted on a rail or track 112 to position the robot 110 laterally within the factory interface 102, thereby increasing the range of motion of the dry robot 110 without requiring large or complex robot linkages.
- the dry robot 110 additionally is configured to receive substrates from the cleaner 104 and return the clean polish substrates to the substrate storage cassettes 114.
- the polishing module 106 includes a plurality of polishing stations 124 on which substrates are polished while retained in one or more polishing heads 126.
- the polishing stations 124 are sized to interface with two or more polishing heads 126 simultaneously so that polishing of two or more substrates may occur using a single polishing station 124 at the same time.
- the polishing heads 126 are coupled to a carriage 220 (shown in Figure 2) that is mounted to an overhead track 128 that is shown in phantom in Figure 1.
- the overhead track 128 allows the carriage 220 to be selectively positioned around the polishing module 106 which facilitates positioning of the polishing heads 126 selectively over the polishing stations 124 and load cup 122.
- the overhead track 128 has a circular configuration which allows the carriages 220 retaining the polishing heads 126 to be selectively and independently rotated over and/or clear of the load cups 122 and the polishing stations 124.
- the overhead track 128 may have other configurations including elliptical, oval, linear or other suitable orientation and the movement of the polishing heads 126 may be facilitated using other suitable devices.
- two polishing stations 124 are shown located in opposite corners of the polishing module 106. At least one load cup 122 is in the corner of the polishing module 106 between the polishing stations 124 closest the wet robot 108. The load cup 122 facilitates transfer between the wet robot 108 and the polishing head 126.
- a third polishing station 124 (shown in phantom) may be positioned in the corner of the polishing module 126 opposite the load cups 122.
- a second pair of load cups 122 (also shown in phantom) may be located in the corner of the polishing module 106 opposite the load cups 122 that are positioned proximate the wet robot. Additional polishing stations 124 may be integrated in the polishing module 106 in systems having a larger footprint.
- Each polishing station 124 includes a polishing surface 130 capable of polishing at least two substrates at the same time and a matching number of polishing units for each of the substrates.
- Each of the polishing units includes a polishing head 126, a conditioning module 132 and a polishing fluid delivery module 134.
- the conditioning module 132 may be a conditioner which dresses the pad by removing polishing debris and opening the pores of the pad.
- the polishing fluid delivery module 134 may be a slurry delivery arm.
- the polishing surface 130 is supported on a platen assembly (not shown) which rotates the polishing surface 130 during processing.
- the polishing surface 130 is suitable for at least one of a chemical mechanical polishing and/or an electrochemical mechanical polishing process.
- the platen may be rotated during polishing at a rate from about 10 rpm to about 150 rpm, for example, about 50 rpm to about 110 rpm, such as about 80 rpm to about 100 rpm.
- Figure 2 is a partial side view showing one embodiment of one of the polishing stations 124 of Figure 1. Only one of the two or more polishing units is shown in Figure 2 for ease of explanation.
- a platen assembly 200 supports a dielectric polishing pad 204. The upper surface of the pad 204 forms the polishing surface 130.
- the platen 202 is movably supported on an inner frame 203 by one or more bearings 212.
- the platen 202 is coupled by a shaft 206 to a motor 208 that is operable to rotate the platen assembly 200.
- the motor 208 may be coupled by a bracket 210 to the inner frame 203.
- the motor 208 is a direct drive motor.
- Other motors may also be utilized to rotate the shaft 206.
- the motor 208 is utilized to rotate the platen assembly 200 such that the pad 204 retained thereon is rotated during processing while the substrate 170 is retained against the polishing surface 130 by the polishing head 126.
- the polishing head 126 is rotated at a rate from a range of about 10 rpm to about 150 rpm, for example, about 50 rpm to about 110 rpm, such as about 80 rpm to about 100 rpm.
- the polishing head 126 may press the substrate 170 against the pad 204 at a pressure in range of about 0.5 psi to about 5.0 psi, for example, about 1 psi to about 4.5 psi, such as about 1.5 psi to about 4.0 psi, for example.
- the polishing head 126 may have a moving range preferably from about 10 to 14 inches.
- the polishing head 126 may be sweeping from a frequency of about 1 sweep per minute (swp/min) to about 40 swp/min, for example, about 5 swp/min to about 30 swp/min, such as about 12 swp/min to about 25 swp/min. Each sweep may be about 10 to about 14 inches.
- the platen assembly 200 is large enough to support a polishing pad 204 which will accommodate polishing of at least two substrates retained by different polishing heads 126 and served by different polishing units.
- the dielectric polishing pad 204 has a diameter greater than about 30 inches, for example, between about 30 and about 52 inches, such as 42 inches. Even though the dielectric polishing pad 204 may be utilized to polish two substrates simultaneously, the pad unit area per number of substrate simultaneously polished thereon is much greater than conventional single substrate pads, thereby allowing the pad service life to be significantly extended.
- the conditioning module 132 may be activated to contact and condition the polishing surface 130. Additionally, polishing fluid is delivered through the polishing fluid delivery module 134 to the polishing surface 130 during processing. The distribution of polishing fluid provided by the polishing fluid delivery module 134 may be selected to control the distribution of polishing fluid across the lateral surface of the polishing surface 130. It should be noted that while only one polishing head 126, conditioning module 132 and polishing fluid delivery module 134 are depicted in Figure 2, more numbers of polishing heads and conditioning modules, polishing fluid delivery modules are possible. For the sake of clarity, there is sufficient room to accommodate at least one additional polishing unit on the pad 204, as shown in Figure 1. One embodiment includes at least two sets of polishing heads 126, conditioning modules 132 and polishing fluid delivery modules 134 working simultaneously to accommodate for the polishing of at least two substrates simultaneously on one polishing pad 204.
- FIG. 3 is a flowchart of a method for simultaneously polishing multiple substrates on a single polishing surface that may be practiced in any polishing station embodiments described herein.
- the polishing method may be practiced in other suitable adapted systems, including those from the equipment manufacturers.
- the method 300 begins at step 310, wherein a first substrate and a second substrate are pressed against a single polishing surface 130 of a polishing module 106 while the surface 130 is rotated.
- a first slurry delivery arm 134 in front of the first substrate delivers a polishing liquid to the surface 130 in front of the first substrate.
- the area of the pad to be rotated under the substrates is the "front” while the area of the pad just rotated from below the substrate is the "back.”
- the polishing fluid may be delivered to the pad surface 130 from the first slurry delivery arm 134 at a rate of about 100 seem to about 1000 seem, for example, about 200 seem to about 800 seem, such as about 300 seem to about 600 seem from each arm.
- a second slurry delivery arm 135 in front of the second substrate delivers a polishing fluid to the area in front of the second substrate.
- the second slurry delivery arm 135 may provide fluid to the pad at substantially the same rate as the first arm 134.
- the overall amount of slurry used per substrate may be reduced since both the substrates and the pad are polished with the same slurry agent. As a result, a reduced amount of slurry may be used to polish the next substrate.
- silica may be used as the slurry agent.
- the parameters for the slurry usage rate per slurry delivery arm may be range from about 100 seem to about 1000 seem, for example, for about 200 seem to about 800 seem, such as about 300 seem to about 600 seem.
- the slurry delivery arm may sweep the polishing surface with a frequency from a range of about 1 swp/min to about 70 swp/min, preferably, for about 5 swp/min to about 60 swp/min, and more preferably, for about 10 swp/min to about 60 swp/min, for example.
- the movement of the slurry delivery arm may be from a range of about 2 inches to about 18 inches, for example, for about 6 inches to about 16 inches, such as about 7 inches to about 13 inches.
- the first and second substrates are polished in the presence of the polishing fluid. Conditioning may occur before, during or after polishing. Conditioning while polishing has shown good results. While the substrate has been polished in the presence of the polishing fluid, an end point detection device coupled with the polishing station may be used to determine the removal rate of the metal layer. In one embodiment, eddy current endpoint detection may be used to monitor the removal rate of the metal layer. In another embodiment, optical techniques, such as In Situ Removal Monitor (ISRM) laser endpoint detection may be used to monitor the removal rate of material from the substrate and/or to detect the polishing endpoint.
- ISRM In Situ Removal Monitor
- step 340 while the first substrate is still pressed against the polishing surface 130, the polishing surface 130 is conditioned with a first conditioner 132 at a location behind the first substrate.
- step 350 while the second substrate is still pressed against the polishing surface 130, the polishing surface is conditioned with a second conditioner 133 at a location behind the second substrate.
- the conditioner may include a diamond-containing surface that is swept across the polishing surface at a frequency of about 1 swp/min to about 40 swp/min, for example, about 5 swp/min to about 30 swp/min, such as about 12 swp/min to about 25 swp/min.
- the conditioner may have a sweep distance of about 0.5 to about 21 inches, for example, 1.0 to about 20 inches.
- the conditioner may rotate the diamond-containing surface against the pad 304 at a rotation rate of about 10 rpm to about 300 rpm, for example, about 50 rpm to about 200 rpm, such as about 80 rpm to about 150 rpm, for example.
- each substrate may be polished utilizing a two-step process.
- a first step includes removing the bulk thickness of copper followed by a copper clearance step.
- the bulk removal step ends at or about when the underlying material begins to be exposed through the copper layer.
- the bulk removal step may remove copper at a polishing rate of between about 9,000 to about 10,000 A/min.
- the platen speed may be maintained between about 83 to 113 revolutions per minute (rpm) while the head is rotated between about 77 and about 107 revolutions per minute.
- the polishing head may be oscillated with a frequency of about 19 sweeps per minute through a distance of between 10 to about 14 inches.
- the substrate is pressed against the polishing surface at a pressure of between about 2.2 to about 2.9 psi.
- a low silica content slurry having neutral pH may be utilized at about 300 seem per slurry delivery arm.
- the slurry delivery arm may be swept between about 9 to 11 inches with a frequency of 19 to about 38 sweeps per minute.
- the conditioner may be pressed against the pad with a force of between about 3 to about 5 psi while being rotated at about 108 rpm.
- the conditioner may be swept over a distance of about 1.5 to about 20 inches.
- the copper clearance step may remove copper to expose a barrier layer at a rate of between 4,000 to 5,000 A/min.
- the platen may be rotated about 83 to 113 revolutions per minute while the polishing head is rotated between about 77 to about 107 rotations per minute.
- the substrate is pressed against the polishing pad with a force of between 1.1 to about 1.3 psi while the head is swept over a distance of about 10 to about 14 inches with a frequency of about 19 sweeps per minute.
- a low silica content polishing slurry having neutral pH may be provided at a rate of about 2 seem per slurry delivery arm.
- the slurry delivery arm may be swept over a distance of about 9 to about 12 inches with a frequency of 19 to about 38 sweeps per minute.
- the conditioner may be pressed against the polishing surface while processing substrate with a force of between about 3 psi to about 5 psi while rotating the conditioner with an rpm of about 108, while sweeping the conditioner over a distance between about 1.5 to about 20 inches.
- the invention provides an improved method for the CMP process by providing a pad large enough to accommodate polishing at least two substrates simultaneously while also providing a clean and conditioned polishing surface after each polishing of the substrates. Copper polish rates up to about 20,000 Angstrom per minute (A/min) may be obtained, for example, about 2,000 A/min to about 15,000
- A/min such as about 3,000 A/min to about 12,000 A/min, for example, have been realized with good match of substrate to substrate results.
- the improved polishing repeatability and extended life of the polishing surface is advantageously obtained.
