New description: [New technical field] This work is about a grinder, especially a grinder with ultraviolet light irradiation unit and suitable for chemical mechanical polishing (Chemica丨Meehanieal Polishing; CMP). [Prior Art] In the development of the semiconductor industry, the chemical mechanical polishing process is a preferred method for polishing or polishing a + conductor substrate. Chemical Mechanical Polishing, or Chemical Mechanics, is a chemical polishing agent (ie, a polishing slurry) that is ground on a polishing pad of a grinder. The action of the object to be polished (for example, wafer) is to flatten the dielectric layer and the metal layer on the member to be polished to be fully planarized to provide the next layer of circuit formation, thereby achieving three-dimensional wiring or multilayer wiring. Increase the pattern density while reducing the defect density and improving the process yield. In the field of semiconductor technology, chemical mechanical polishing using nanotechnology is currently the most effective method for achieving wafer surface flattening. The main factors affecting the chemical mechanical polishing efficiency include: the rotational speed of the wafer and the grinding crucible, the chemical composition of the grinding and grinding particles, the polishing temperature, the material of the polishing pad, and the surface roughness of the polishing pad. As shown in FIG. 1 , it is a conventional chemical mechanical grinding mill 1 which comprises a grinding wheel, a support frame 13 , a bearing table 12 , a grinding (4) supply M419644 single weir 14 , and a rotating unit (not shown). ) and other components. The polishing pad η is disposed above the load σ12 and is rotatable by the rotation unit. Generally, the material of the polishing pad 11 is usually an opaque material (for example, polyamine methacrylate) and the carrier 12 is made of a metal material. It is placed under the support frame 13. The support frame pushes the wafer 1 in the direction of the grind mark 11. The abrasive slurry supply unit 丨4 provides a polishing slurry, and the abrasive slurry flows between the wafer i 〇 and the polishing 塾1 i. The abrasive slurry generally contains a chemical material that chemically dissolves the wafer 10 and an abrasive material that physically removes the surface portion of the wafer 10. However, conventional chemical mechanical polishing still does not achieve very good results, and sometimes there is a case where the chemical material reacts well with the object to be polished to cause a flat abrasive surface. Because & 'If you can use the illumination method to improve the reactivity of the polishing slurry with the object to be polished, it can not only improve the grinding effect of chemical mechanical polishing, but also shorten the grinding time and provide the factory production. [New content] The main purpose is to provide a grinding machine, preferably for chemical mechanical polishing, which can provide ultraviolet light irradiation during the grinding process to enhance the grinding effect, and can also shorten the production rate of the m-plant production. 1: The mill 'includes ···the carrying platform' has a plurality of through-holes of the carrying platform; the rotating unit is connected with the carrying platform to rotate the carrying platform; a grinding potential, matching The material of the polishing pad is a light transmissive material; the abrasive material supply unit 俜M419644 provides a polishing slurry to the surface of the poem; at least the ultraviolet light is coupled to the carrier; And a control module, which is respectively connected to the ultraviolet light unit and connected to the ultraviolet light unit, wherein the ultraviolet light emits ultraviolet light, and the ultraviolet light passes through the carrier. The holes are irradiated to the polishing slurry. In the grinding machine of the present invention, since the material of the polishing crucible is a light transmissive material, and the carrying platform has a plurality of through holes, the ultraviolet light emitted by the external illumination unit disposed under the carrying platform can pass through the carrying platform. The through holes are directly irradiated to the polishing slurry. In this way, during the operation of the grinder (in the process of chemical mechanical polishing), the ultraviolet light can be directly irradiated to the contact surface of the grinding (4) and the member to be polished (instead of indirect irradiation, such as reflection), improving the chemical mechanical polishing efficiency, and making the chemical Mechanical grinding is accelerated. The conventional grinding machine is not equipped with an ultraviolet light unit, so the polishing efficiency cannot be improved by illumination. In addition, even if the external light unit is placed above the polishing pad in the conventional grinding machine, the ultraviolet light cannot be directly "irradiated" to the contact surface of the polishing slurry and the member to be polished, so that the efficiency of irradiating the ultraviolet light is limited. The efficiency of chemical mechanical polishing cannot be greatly improved. However, the grinding machine of the present invention can directly irradiate ultraviolet light to the contact surface of the polishing slurry and the workpiece to be polished, so that the effect of improving the chemical mechanical polishing efficiency and accelerating the chemical mechanical polishing rate can be achieved. The grinding machine of the present invention preferably further includes a stopper which is disposed on the grinding ram. When the workpiece to be polished is disposed on the grinding ram, the stopper is disposed on one side of the workpiece to be polished. The stopper does not move with the rotation of the stage, so that the piece to be polished can be stopped in one place, so that the piece to be polished does not flow clockwise or counterclockwise with the rotating material. The number of stops used can be adjusted as needed. Compared with the support frame used in the conventional grinding machine (as shown in Fig. 1, it is disposed above the workpiece to be polished, and the workpiece is fixed by suction). The structure is relatively simple 'operation is also convenient. In the grinding machine of the present invention, the polishing pad is preferably in the shape of a disk, and the material of the polishing pad is preferably selected from the group consisting of i: glass, quartz, and oxidized. The thickness of the polishing pad may preferably be from 5 mm to 80 mm, and the thickness of the polishing pad may decrease with the number of uses. In the grinder of the present invention, the wavelength of the ultraviolet light is preferably from 100 nm to 400 nm. In the grinder of the present invention, the ultraviolet light unit is preferably arranged in a geometric shape. For example, when the number of ultraviolet illumination light units is six, they may exhibit a positive hexagonal arrangement with each other; #When the number of ultraviolet illumination light units is seven, 'they may exhibit a regular heptagon arrangement with each other to increase Illumination uniformity. In the grinding machine of the present invention, the grinding machine is preferably used for grinding a group selected from the group consisting of a stone anti-fossil wafer, a stone wafer, a nitride wafer, and a wafer. That is, the material to be polished may be a carbonized wafer, a stone wafer, a gallium nitride wafer, an aluminum oxide wafer, or other semiconductor substrate. In the grinding machine of the present invention, the ultraviolet light unit may preferably be a light emitting diode (LED), and the heat of the ultraviolet light unit is particularly limited as long as ultraviolet light can be emitted. 7 M41^644 In the grinding machine of the present invention, the control module preferably controls the carrying platform (4) to turn it, and the control module preferably controls the ultraviolet light unit to emit ultraviolet light, that is, the switch for controlling the ultraviolet light unit. In addition, the control module preferably also controls the illuminance (or 'intensity", and/or time of the ultraviolet light emitted by the ultraviolet light unit, so that the chemical reaction rate, time, etc. can be adjusted according to requirements. In the machine, when the workpiece to be polished is disposed on the polishing pad for grinding, the polishing slurry flows between the workpiece to be polished and the polishing pad, and the ultraviolet light irradiated to the polishing slurry can cause the polishing slurry to be carried out or strengthened. Chemical reaction. In the grinding machine of the present invention, the composition of the polishing slurry preferably includes a group selected from the group consisting of hydrogen peroxide, nitric acid, potassium citrate, ferricyanide, barium sulfate, and mixtures thereof. Preferably, the composition of the abrasive slurry further comprises abrasive particles, and the material of the abrasive particles is preferably selected from the group consisting of alumina, dioxin, oxidization, and mixtures thereof. The particle size is preferably "claw to curse between the claws. In the grinding machine of the present invention, the carrying table is preferably disc-shaped, and the material of the carrying platform is preferably free: aluminum, stainless steel, A group consisting of titanium and its alloy. The diameter of the through hole of the carrying platform is preferably from 1 〇〇 to 1 50 mm, which can be adjusted according to the needs of use. In the present invention, the bearing platform is used to support the polishing pad and is supported. The table is connected to the rotating unit to be rotatable and ground. The through hole of the carrying table is used to pass the ultraviolet light, so the diameter and distribution density of the through hole are adjusted according to the use requirements. M419644 The grinding machine of the present invention is preferably Furthermore, a substrate support frame is attached to the polishing pad. When a workpiece to be polished is disposed on the polishing pad, the substrate support frame is disposed on the workpiece to be polished. Method of absorbing Below the carrier. Therefore, in the grinding machine of the present invention, since the material of the polishing pad is a light-transmitting material, and the carrying platform has a plurality of through holes, the ultraviolet light unit disposed under the carrying platform can emit ultraviolet light. Light, and the ultraviolet light is passed through the through hole of the carrying platform, and directly irradiated to the polishing slurry. Thus, during the operation of the grinder (in the process of chemical mechanical polishing), the ultraviolet light can be directly irradiated to the polishing slurry. The contact surface with the member to be polished (instead of indirect irradiation), the chemical mechanical polishing efficiency is improved, and the chemical mechanical polishing is accelerated. [Embodiment] [Example 1] Please refer to FIG. 2 and FIG. a grinder 2 comprising: a carrier 22' having eight through holes 22 1 extending through the carrier 22; a #rotating unit 23 coupled to the carrier 22 for rotating the carrier 22; The mat 21 is attached to the loading table 22, and the material of the polishing pad 21 is glass; the polishing slurry supply unit 24 provides a polishing mass 27 to the surface of the polishing pad 21; The unit 25 is disposed under the loading platform 22; three stops 28 are disposed on one side of the workpiece 3 to be polished; and a control module 26 is respectively associated with the rotating unit 23 and the ultraviolet light unit 25; wherein the ultraviolet light unit 25 emits an ultraviolet 9 M419644 light and the ultraviolet light passes through the through hole 2 1 of the stage 22 to be irradiated to the polishing slurry 27. In the present embodiment, the member to be polished 3 is a tantalum carbide substrate, and the components of the polishing slurry 27 used include hydrogen peroxide, alumina abrasive particles (having an average diameter of about 100 nm) and the like. The material of the carrier 22 is aluminum, wherein the through hole is formed to have a diameter of about 80 mm; the polishing pad 21 is made of glass and has a thickness of 50 mm; and the ultraviolet light unit 25 is a light emitting diode unit. The control module 26 controls the rotational speed of the stage 22, the switch of the ultraviolet illumination unit 25, the illumination of the ultraviolet illumination unit 25, and the illumination time of the ultraviolet illumination unit 25. When the grinding is performed using the grinder 2 of the present embodiment, the polishing slurry supply unit 24 drops the polishing slurry 27 onto the polishing pad 21, and the polishing slurry 27 flows between the polishing pad 21 and the polishing member 3. The rotating unit 23 rotates the stage 22 and the grinding boring 21, but the ultraviolet light unit located below the stage 22 is stationary. When the through hole 221 is moved over the ultraviolet light unit 25, ultraviolet light passes through the through hole 2 and the polishing pad 21 of the light transmitting material, and is irradiated to the polishing slurry 27. Accordingly, in the present invention, the ultraviolet light emitted from the ultraviolet light unit 25 disposed under the stage 22 can be directly irradiated to the polishing slurry 27 through the through hole 221' of the stage 22. Thus, during the operation of the grinder 2 (in the process of chemical mechanical polishing), the ultraviolet light can be "directly" irradiated to the contact surface of the spun material 27 and the member to be polished 3, instead of indirect irradiation, thereby improving the chemical mechanical polishing efficiency. And accelerate the chemical mechanical polishing. [Embodiment 2] The grinder 2 of the present embodiment is substantially the same in construction as the grinder 2 of the embodiment i, but the difference is that, as shown in Fig. 4, the stage 22 of the grinder 2 of the present embodiment The through hole 221 has a small diameter (about 40 mm) and a large number. Therefore, when the polishing is progressed (when the stage 22 is rotated), the ultraviolet light emitted from the outer beam light unit 25 under the stage 22 is more easily irradiated onto the upper polishing slurry 27. In summary, since the conventional grinder is not equipped with an ultraviolet light unit, the polishing efficiency cannot be improved by illumination. In addition, even if the ultraviolet light unit is added to the polishing pad in the conventional grinding machine, the external light can not be directly irradiated to the contact surface of the polishing slurry and the workpiece to be polished, so the efficiency of irradiating the ultraviolet light is limited. The efficiency of chemical mechanical polishing cannot be greatly improved. However, in the grinding machine of the present invention, since the material of the polishing pad is a light-transmitting material, and the carrying platform has a plurality of through holes, the ultraviolet light emitted from the ultraviolet light unit disposed under the carrying table can pass through the carrying platform. The through holes are directly irradiated to the polishing slurry. In this way, during the operation of the grinder (in the process of chemical mechanical polishing), the ultraviolet light can be directly irradiated to the contact surface of the polishing slurry and the member to be polished (instead of indirect irradiation, such as reflection), so that the chemical mechanical polishing can be surely achieved. Efficiency, and the effect of accelerating the rate of chemical mechanical polishing.
