`
`VI. Description:
`
`[TECHNICAL FIELD]
`
`The present invention relates to a conditioner, particularly to a composite conditioner
`
`of a CMP pad and a method for manufacturing the same.
`
`[PRIOR ART]
`
`Chemical mechanical planarization (CMP) is currently the most attractive technology
`
`in the process of planarization of semiconductor wafers. In the CMP process, the function
`
`of a polishing pad is to stably and uniformly transport a polishing solution to between a
`
`wafer and the polishing pad. Under the interaction of chemical etching and mechanical
`
`grinding, the protruding deposited layer on the chip is removed.
`
`In order to meet the needs of wafer processing and mass production and maintain the
`
`stability of quality, a diamond conditioner (diamond dresser) must be used to condition the
`
`polishing pad in a timely manner during the CMP process. The diamond conditioner
`
`removes the polishing byproducts on the surface, restores the rough surface of the
`
`polishing pad, improves its ability to accommodate the slurry, and restores the pores on the
`
`surface of the polishing pad and its ability to hold and transport the polishing solution. In
`
`this way, the cost of polishing pads can be reduced and the requirement for stable quality
`
`during wafer mass production can be met.
`
`A conventional diamond conditioner fixes diamond particles of an average particle
`
`size on a metal disc. This diamond conditioner is suitable for conditioning hard polishing
`
`pads (e.g., IC1000). A conventional conditioner not only needs to remove the waste
`
`generated during polishing of wafers but also needs to cut a layer of polishing pad to
`
`restore certain roughness of the polishing pad, but this conventional type of diamond
`
`conditioner is not suitable for the CMP process of below 45 nm. As the line width of
`
`integrated circuits is getting smaller, for example, a 65 nm process was implemented as of
`
`2006, the requirements for flattening and smoothness of the wafer surface are getting
`
`higher, and the requirements for conditioning polishing pads are also increasing. It is
`
`expected that in the 45nm process in 2010, the polishing must adopt an extremely low
`
`pressure to avoid wearing through the nano-scale copper wires and the fragile low-k
`
`resistance layer. Therefore, the conditioned polishing pad needs higher flatness and needs
`
`to be redesigned to meet the requirements of large-size wafers. In the future, higher
`
`requirements will be set for the diamond particle distribution rules and leveling of
`
`3
`
`Page 6 of 58
`
`KINIK EXHIBIT 1017
`
`
`
`21100198
`
`diamond conditioners. In addition, the conditioner also needs to score finer and more
`
`uniform marks on the polishing pad, but conversely, the conditioner shall have a lower
`
`removal rate of the polishing pad. Such requirements cannot be met by conventional
`
`conditioners.
`
`There are patents for different conditioners. For example, Taiwan patent I228066
`
`discloses a conditioner for polishing cloth and a method for conditioning the polishing
`
`cloth. The conditioner comprises a metal table provided with an adjusting mechanism to
`
`adjust the height difference of a reference plane formed by front ends of most grindstone
`
`particles in all or some of the grindstone particle groups.
`
`Taiwan public patent 200821093 discloses a diamond conditioner, wherein different
`
`types of diamond grits are respectively bonded to diamond grit bonding portions, and the
`
`diamond grit bonding portions are fixed to a conditioner substrate by bolts or adhesive.
`
`US patent US6, 054, 183 discloses a conditioner, wherein a plurality of diamond
`
`particles and a layer of CVD diamonds are formed on a substrate; and the plurality of
`
`diamond particles are clad with the CVD diamonds, thereby being fixed to the substrate
`
`surface.
`
`International patent with publication number WO00/64630 discloses that a polishing
`
`layer comprises a plurality of grits, and the grits comprises organic resin, metal salt and
`
`diamond grits averagely distributed among a plurality of grits.
`
`US public patent US20060128288 discloses a conditioner, comprising a plurality of
`
`diamond particles fixed to a metal substrate by a metal adhesive.
`
`Japanese public patent JP2006-315088 discloses a conditioner comprising a
`
`disc-shaped base bonded to a plurality of round PCD diamond pieces.
`
`In general, the diameter of a conditioner is approximately 108 mm. Due to the large
`
`area, the amount of deformation is large, too. It is not easy to bond various grits of
`
`different sizes, shapes and materials and keep the apices of most grits at the same height.
`
`Further, conditioners with a large area are expensive.
`
`[SUMMARY OF THE INVENTION]
`
`In order that a conditioner with a large area can more easily bond various grits of
`
`different sizes, shapes and materials and keep the apices of most grits at the same height,
`
`the present invention is proposed.

`
`A main object of the present invention is to provide a composite conditioner in a way
`
`that the same polishing end of a large substrate bonds most of the small substrates having
`
`grits, the cutting ends of a plurality of grits are kept at the same height easily and various
`
`grits of different sizes, shapes and materials are bonded more easily.
`
`Other objects and effects of the present invention are shown in the drawings and
`
`embodiments. The detailed description is as follows.
`
`[DETAILED DESCRIPTION]
`
`As shown in Fig. 1 and Fig. 2, a composite conditioner 1 in the first embodiment of
`
`the present invention, particularly a conditioner used as a CMP pad, comprises a large
`
`substrate 11 and a plurality of polishing units 12.
`
`As shown in Fig. 2, the large substrate 11 is provided with a bonding surface 110, a
`
`bottom surface 111 and a plurality of through holes 112 corresponding to a plurality of
`
`polishing units 12; the plurality of through holes 112 respectively accommodate the
`
`plurality of polishing units 12 and the plurality of polishing units 12 protrude from the
`
`bonding surface 110; and the plurality of polishing units 12 and the large substrate 11 are
`
`fixed and bonded with a bonding agent 13.
`
`The plurality of polishing units 12 respectively comprise a small substrate 120 and a
`
`plurality of grits 121; a side 122 of the small substrate 120 bonds the plurality of grits 121;
`
`each grit 121 has a cutting end 123 that can cut a work piece; the other side 124 of the
`
`small substrate 120 opposite to the side provided with the plurality of grits 121 and the
`
`bottom surface 111 of the large substrate 11 are approximately on the same reference plane
`
`14. A plurality of inner walls 113 forming a plurality of through holes 112 of the large
`
`substrate 11 and a plurality of outer walls 125 of the plurality of polishing units 12
`
`respectively have a plurality of concave-convex structures 114 and 126. After the bonding
`
`agent 13 permeates into the plurality of concave-convex structures 114 and 126 and is
`
`cured to bond the plurality of inner walls 113 and the plurality of outer walls 125, the
`
`bonding between the large substrate 11 and the plurality of polishing units 12 will be even
`
`firmer. In a polishing operation, the plurality of polishing units 12 cannot move
`
`perpendicularly relative to the large substrate 11, so they will not break away from the
`
`large substrate 11. Alternatively, the plurality of concave-convex structures 114 and 126
`
`are not arranged in the plurality of inner walls 113 and the plurality of outer walls 125, or
`
`are arranged in either the plurality of inner walls 113 or the plurality of outer walls 125.

`
`As shown in Fig. 1, the section between the plurality of through holes 112 of the large
`
`substrate 11 and the plurality of polishing units 12 may be round or polygonal, for
`
`example in a square shape.
`
`The plurality of polishing units 12 in this embodiment are respectively higher than the
`
`large substrate 11. From the height of the plurality of polishing units 12, the height that a
`
`plurality of cutting ends 123 of a plurality of grits 121 protrude from the bonding surface
`
`110 of the large substrate 11 is determined. The difference in the height that the plurality
`
`of cutting ends 123 protrude from the large substrate 11 is within 20 microns to keep the
`
`height difference between the plurality of cutting ends 123 and a plane 15 within 20
`
`microns. The height that the plurality of cutting ends 123 protrude from the bonding
`
`surface 110 of the large substrate 11 is 0.05 to 5 mm.
`
`As shown in Fig. 2 and Fig. 3, a composite conditioner 2 in the second embodiment of
`
`the present invention is roughly the same as the composite conditioner 1 in the foregoing
`
`first embodiment in terms of structure except that a plurality of through holes 212 of a
`
`large substrate 21 are in a tapered shape, the diameter of the through holes are larger at the
`
`top and smaller at the bottom and the tilt angle of inner walls 213 is 1 to 15 degrees. The
`
`large substrate 21 is provided with a bonding surface 210, a bottom surface 211 and a
`
`plurality of through holes 212 corresponding a plurality of polishing units 12, the plurality
`
`of inner walls 213 forming the plurality of through holes 212 of the large substrate 21 also
`
`have a plurality of concave-convex structures 214 opposite to the plurality of
`
`concave-convex structures 126; the plurality of polishing units 12 are respectively placed
`
`in the plurality of through holes 112, the other side 124 of the plurality of grits 121 is
`
`inlaid in the lower end of one of the plurality of through holes 212 with a smaller diameter
`
`in a clamped manner and in on the same reference plane 14 with the bottom surface 211,
`
`and then are fixed and bonded with a bonding agent 22. During a polishing operation,
`
`when a plurality of polishing units 12 are pressed, perpendicular movement should be
`
`avoided, and the plurality of through holes 212 are designed to be in a tapered shape for
`
`the purpose of ensuring that the plurality of polishing units 12 when being pressed are
`
`unable to move towards the narrower sides of the plurality of through holes 212, thereby
`
`becoming firmer. Alternatively, the plurality of concave-convex structures 214 are 126 are
`
`not arranged in the plurality of inner walls 213 and the plurality of outer walls 125, or are
`
`arranged in either the plurality of inner walls 213 or the plurality of outer walls 125.
`
`As shown in Fig. 2, Fig. 4A and Fig. 4B, a composite conditioner 3 in the third

`enter the template 32, the amount of protrusion of the plurality of polishing units 31 is
`
`controlled through the thickness of the template 32, then a bonding agent 13 is injected
`
`from the plurality of through holes 112 of the large substrate 11 so that the large substrate
`
`11 is fixed and bonded to the plurality of polishing units 31, and then the template 32 is
`
`separated from the large substrate 11 to form a composite conditioner 3 as shown in Fig.
`
`4A.

`grooves 511 of the large substrate 51 respectively accommodate a plurality of polishing
`
`units 12; the plurality of polishing units 12 and the large substrate 11 are fixed and bonded
`
`by means of close fit. In this embodiment, the polishing units 12 are mechanically
`
`squeezed into the metal accommodating grooves 511 of the large substrate 51 and are
`
`fixed using the deformation of the concave-convex structures, and finally, a bonding agent

`provided with a plurality of grits 121 has a certain distance from a plurality of bottom
`
`walls 612 forming bottoms of the plurality of accommodating grooves 611 of the large
`
`substrate 61; and the bonding agent 13 is respectively filled between the other side 124 of
`
`the plurality of grits 121 and the plurality of bottom walls 612.

`
`The bonding agent of the present invention is made of metal, metal alloy, polymer,
`
`ceramic, or a mixture of the foregoing materials, polymer is a representative embodiment,
`
`and the bonding agent may also be made of a welding alloy material.
`
`The large substrate of the present invention may be in a disc shape, with a diameter of
`
`approximately 90 to 120 mm. The small substrates may be in a disc shape, with a diameter
`
`of approximately 10 to 30 mm, preferably 20 mm. The size of the grits is 100 to 500
`
`microns, preferably 160 to 200 microns. A preferred embodiment of the large substrate of
`
`the present invention is stainless steel; a preferred embodiment of the bonding agent may
`
`be resin; and a preferred embodiment of the method for fixing the grits and the small
`
`substrates may be resin gluing or bonding by copper zinc alloy containing chromium and
`
`titanium; the external surface of the small substrates has a nickel-containing electroplated
`
`layer.
`
`The present invention adopts a composite method, a plurality of polishing units are
`
`manufactured at first, it is easier for smaller polishing units to make cutting ends of most
`
`grits at the same height, then a large substrate bonds a plurality of polishing units to form a
`
`large-area composite conditioner, and it is easier to make the cutting ends of most grits of
`
`a large-area composite conditioner at the same height. The advantage of the present
`
`invention is that the manufacturing of smaller polishing units has a lower cost and the
`
`composite conditioner may change grits as needed. For example, diamonds in a larger
`
`particle size may be used on the outer ring of the composite conditioner, and diamonds in a
`
`smaller particle size may be used on the inner ring; or diamonds with a poor cutting ability,
`
`but high wear resistance and a complete crystal form may be used on the outer ring, and
`
`diamonds with a good cutting ability, but lower wear resistance and a poor crystal form
`
`may be used on the inner ring. The diamond particles of the same small polishing unit are
`
`the same in size, shape and material, but the diamond particles of a plurality of polishing
`
`units in the composite conditioner may be the same or different in size, shape and material.
`
`A plurality of polishing units are combined into a larger composite conditioner. The
`
`cutting rate and wear rate of the composite conditioner can be controlled.
`
`The above record is only embodiments applying the technical content of the present
`
`invention. All the modifications and changes made by those skilled in the art by using the
`
`present invention shall fall in the scope of the claims of the present invention. The present
`
`invention is not limited to the embodiments.
