[0031] Among the benefits and improvements disclosed, other objectives and advantages of this disclosure will become apparent from the following description, accompanied by the accompanying figures. While detailed embodiments of this disclosure are disclosed herein, it should be understood that the disclosed embodiments are merely illustrative examples of the various forms in which this disclosure may be embodied. Furthermore, each of the examples given with respect to the various embodiments of this disclosure is illustrative and not limiting.
[0032] Prior patents and publications referenced herein are incorporated in their entirety by reference.
[0033] Throughout this specification and the claims, the following terms have the meanings expressly relating to this specification unless the context explicitly specifies otherwise. The phrases “in one embodiment,” “in an embodiment,” and “in some embodiments” as used herein may refer to, but not necessarily, the same embodiment. Furthermore, the phrases “in another embodiment” and “in some other embodiments” as used herein may refer to, but not necessarily, different embodiments. All embodiments of this disclosure are combinable without departing from the scope or spirit of this disclosure.
[0034] As used herein, the term “based on” is non-exclusive and allows for the basis of additional factors not explicitly stated, unless the context otherwise explicitly specifies. Furthermore, throughout this specification, the meanings of “a,” “an,” and “the” include multiple references. The meaning of “in” includes “in” and “on.”
[0035] Some embodiments of this disclosure relate to a device for cleaning substrates. The device includes a polymer pad incorporated into a frame body and a coupling member extending upward from the frame body for securing the device to equipment. The frame body and coupling member are constructed from a material that is generally rigider than the soft polymer material used to form the polymer pad. The rigidity of the frame body and coupling member improves the structural integrity of the polymer pad and replaces the soft polymer extension with a rigid coupling member, thereby more securely securing and mounting the device to equipment. Additional advantages, among many other benefits, include easier mounting and removal from equipment, a longer lifespan for the polymer pad, and improved reliability, which will become apparent based on the disclosures herein.
[0036] In some embodiments, the devices disclosed herein are employed to clean or brush substrates, such as silicon wafers used in semiconductor manufacturing. Specifically, in some embodiments, the substrate undergoes polishing processes, such as chemical mechanical planarization (CMP) processes, where chemical oxidation and mechanical abrasion are used to achieve high substrate flatness. Processes such as CMP often result in the formation of various residues and contaminants on the substrate surface. These residues and contaminants need to be removed before further semiconductor manufacturing processes. Therefore, the devices disclosed herein may be useful in post-CMP cleaning modules, pre-CMP cleaning modules, and the like.
[0037] As used herein, the term “residue” refers to particles generated during a process (one or more). The term includes “(one or more) post-CMP residues.” For example, but not limited to, post-CMP residues may include, for example, silica-containing particles, particles from the polishing slurry, reaction by-products of the polishing slurry, carbon-rich particles, polishing pad particles, brush deloading particles, metals (e.g., at least one of copper, aluminum, tungsten, or any combination thereof), metal oxides, organic residues, barrier layer residues, any other materials that are by-products of the CMP process, or any combination thereof. It will be understood that the term may include other types of residues without departing from the scope of this disclosure.
[0038] As used herein, the term “contaminant” refers to one or more undesirable substances. The term includes, for example, at least one of the following: chemicals in a CMP slurry, reaction byproducts of abrasive slurries, any other materials that are byproducts of a CMP process, or any combination thereof. An example of a contaminant is benzotriazole. It will be understood that the term may include other types of contaminants without departing from the scope of this disclosure.
[0039] Figure 1 shows a side view of one non-limiting embodiment of device 100 coupled to a mandrel 202 of apparatus 200. Device 100 may include devices described in any combination of embodiments disclosed herein. In the illustrated embodiment, device 100 includes a polymer pad 102 configured to contact a substrate surface (e.g., to clean, brush, polish, etc.). A coupling member 106, shown, extending upward from a frame body (not shown), is configured to couple device 100 to apparatus 200. In some embodiments, the coupling member 106 is configured to be sufficiently detached to couple device 100 to the mandrel 202 and is also sufficiently elastic to snap back and secure device 100 to the mandrel 202. In some embodiments, the mandrel 202 may further include a groove 204, as shown, for further securing device 100 to the apparatus.
[0040] The side view shows multiple bonding members 106, but in some embodiments, the device 100 includes a single bonding member. In some embodiments, the device 100 includes multiple bonding members. In some embodiments, the polymer pad 102 is formed in the shape of a disk, and the bonding members extend upward from the periphery or outer circumference of the disk. In some of these embodiments, the bonding members may extend around all or part of the outer circumference of the disk.
[0041] Figure 2 is a cross-sectional view of one non-limiting embodiment of device 100, according to several embodiments. Device 100 includes a polymer pad 102, a frame body 104, and a connector 106. The polymer pad 102 has an upper surface 108 and a lower surface 110. The connector 106 is integral with the frame body 104. That is, the connector 106 and the frame body are a single, integral structure formed from the same building material. Since the polymer pad 102 is generally formed from a relatively soft polymer material (e.g., polyvinyl alcohol) for cleaning substrates, the frame body 104 is generally disposed within the polymer pad 102 to provide structural rigidity to device 100. That is, the frame body 104 extends into the polymer pad 102 between the upper surface 108 and the lower surface 110. Furthermore, the frame body 104 includes through holes 112 in the surface of the frame body 104. The through-hole 112 allows the fluid polymer material to be disposed within the through-hole and above and below the frame body 104 during the manufacturing of the device 100, so that when the fluid polymer material solidifies, the resulting polymer pad 102 is formed integrally with at least the frame body 104. The connecting member 106 extends upward from the periphery of the frame body 104 and over the polymer pad 102 in order to connect the device 100 to the apparatus 200.
[0042] The polymer pad 102 generally comprises a material that is softer than the frame body 104 and the binder 106. For example, in some embodiments, the polymer pad comprises a soft polymer material such as polyvinyl alcohol. In some embodiments, the polymer pad comprises at least one of polysulfone, polyethersulfone, polyarylsulfone, nylon, polyamide, fluoropolymer, polytetrafluoroethylene (PTFE), polyethylene, polypropylene, cellulose, acetate, or any combination thereof. In some embodiments, the frame body 104, the binder 106, or any combination thereof comprises a harder polymer material such as at least one of polypropylene, polyethylene, any copolymer thereof, or any combination thereof. In some embodiments, the frame body 104, the coupling member 106, or any combination thereof, comprises a fluid polymer material, which, once solidified, produces a coupling member 106 that is sufficiently elastic so that the coupling member 106 can be bent and sufficiently extensible to bias the clamp inward to engage the device 200 (e.g., snap on to and / or snap off from the mandrel).
[0043] The polymer pad 102 may have a thickness in the range of 0.1 mm to 50 mm, or any range or partial range between 0.1 mm and 50 mm. In some embodiments, for example, the polymer pad 102 may have a thickness in the range of 1 mm to 10 mm, 1 mm to 9 mm, 1 mm to 8 mm, 1 mm to 7 mm, 1 mm to 6 mm, 1 mm to 5 mm, 1 mm to 4 mm, 1 mm to 3 mm, 1 mm to 2 mm, 2 mm to 10 mm, 3 mm to 10 mm, 4 mm to 10 mm, 5 mm to 10 mm, 6 mm to 10 mm, 7 mm to 10 mm, 8 mm to 10 mm, 9 mm to 10 mm, 2 mm to 7 mm, 2 mm to 6 mm, 2 mm to 5 mm, 2 mm to 4 mm, 3 mm to 7 mm, 4 mm to 7 mm, 5 mm to 7 mm, 6 mm to 7 mm, any range or partial range between these, or any combination thereof.
[0044] The diameter of the polymer pad 102 can range from 1 mm to 450 mm, or over any range or partial range between 1 mm and 450 mm. In some embodiments, for example, the polymer pad 102 has a thickness in the range of 1 mm to 25 mm, 1 mm to 50 mm, 1 mm to 75 mm, 1 mm to 100 mm, 1 mm to 125 mm, 1 mm to 150 mm, 1 mm to 200 mm, 1 mm to 300 mm, 1 mm to 450 mm, 25 mm to 450 mm, 50 mm to 450 mm, 75 mm to 450 mm, 100 mm to 450 mm, 125 mm to 450 mm, 150 mm to 450 mm, 200 mm to 450 mm, or 300 mm to 450 mm.
[0045] In some embodiments, the diameter of the polymer pad 102 is less than the diameter of the substrate. In some embodiments, the substrate is a silicon wafer. In some embodiments, the diameter of the polymer pad 102 is less than 25 mm (e.g., 1 mm to 24 mm), less than 51 mm (e.g., 1 mm to 50 mm), less than 76 mm (e.g., 1 mm to 75 mm), less than 100 mm (e.g., 1 mm to 99 mm), less than 125 mm (e.g., 1 mm to 124 mm), less than 150 mm (e.g., 1 mm to 149 mm), less than 200 mm (e.g., 1 mm to 199 mm), less than 300 mm (e.g., 1 mm to 299 mm), or less than 450 mm (1 mm to 449 mm).
[0046] The porosity of the polymer pad 102 can refer to the dimensionless ratio of the volume of void space to the volume of bulk material. In some embodiments, the porosity of the polymer pad 102 is 50% to 99%, or any range or partial range between 50% and 99%. In some embodiments, the porosity of the polymer pad 102 is 60% to 99%, 65% to 99%, 70% to 99%, 75% to 99%, 80% to 99%, 85% to 99%, 90% to 99%, 85% to 95%, 85% to 90%, or 90% to 95%.
[0047] The coupling member 106 eliminates the need for the polymer pad 102 to have any extensions configured to be inserted into the mandrel 202 to secure the device 100 to the apparatus 200. For example, conventional polymer pads have a dovetail joint structure on the upper surface of the polymer pad to connect the conventional polymer pad to the apparatus, but the polymer pad 102 disclosed herein does not include a structure for connecting the polymer pad 102 to the apparatus 200. That is, in some embodiments, the polymer pad 102 has a flat upper surface. In some embodiments, the polymer pad 102 has a non-flat upper surface, and the non-flat upper surface does not have a structure for connecting the polymer pad 102 to the apparatus 200.
[0048] The polymer pad 102 has a lower surface configured for cleaning, polishing, or brushing the substrate surface. In some embodiments, the polymer pad 102 has a flat lower surface. In some embodiments, the polymer pad 102 has a non-flat lower surface. For example, in some embodiments, the polymer pad 102 includes a plurality of surface structures extending from the lower surface of the polymer pad 102. Various embodiments of the surface structures are described below.
