A chemical mechanical polishing machine system includes a polishing table 100 (Polishing Table), a polishing pad 102, a wafer carrier 104, a Slurry tube 108 and a controller 110, among which polishing pad 102 is laid on polishing table 100.

The wafer carrier 104 grasps the back surface of the wafer 106, and presses the front surface of the wafer 104 on the polishing pad 102. The polishing liquid conveying pipe 108 supplies the polishing liquid continuously to the polishing pad 102. Therefore, the chemical mechanical polishing process is that when the protruding part of the front side of the wafer 106 is in contact with the polishing pad 102, the chemical assistant in the polishing liquid can be used to generate a chemical reaction on the front side of the wafer 106. And the abrasive particles in the polishing liquid (Abrasive Particles) are used to assist the mechanical polishing, so as to remove the convex portion on the front surface of the wafer 106. After repeating the above-mentioned chemical reaction and mechanical grinding, the front side of the wafer 106 can be planarized. Usually, the surface of the polishing pad 102 has a plurality of uneven structures that facilitate polishing. Therefore, the surface of the polishing pad 102 appears! Roughness from micron to 2 microns. However, after a general chemical mechanical polishing machine grinds several wafers, the uneven surface of the original polishing pad 102 will become flat, so that the polishing capability of the polishing pad 〖ο? Decreases. In addition, after grinding, the material ground from the wafer 106 may remain on the polishing pad 102, which will change the polishing characteristics and affect the polishing effect. Therefore, usually after polishing several wafers, the adjuster 11 is used to adjust the polishing pad 102, so that the surface of the polishing pad 10 is restored to an uneven surface, and at the same time, the substrate is scraped off. 102 residue.

Among them, the high-pressure liquid source 210 provides water such as water or any other applicable liquid, and the high-pressure lice body source 210 provides a companion evening, and the rolling body 206 is, for example, nitrogen or any other fluid. # I2 ί, which is supplied by a high-pressure liquid source or a high-pressure gas source 21 〇 — \ The pressure of one of the two strong gases 206 is, for example, between 10 psi to 10 (between)而, and the word is used to adjust the grind 塾 102, the adjustment is 544374. 5. Description of the invention (7) The nozzle 2 〇2 of the device 2 2 sprays the surface of Gua and Mo 102 Recover into a concave Y liquid or high-pressure gas 206 to remove the residue in the research 102. Change to an uneven surface and scrape off the liquid or gas pressure liquid source or high-pressure gas source 210 provided in the polishing pad. It is sprayed directly from the nozzle 202, == 2 04 and is passed onto the 塾 102 of the adjusting disk 200. Therefore, the surface of the polishing pad 102 is restored by spraying, pressing liquid or high-pressure gas on the grinding: The high-pressure liquid or high-pressure liquid 206 can grind the residue in the pad 102 and set it as an uneven surface and scrape it. The regulator 220, which is a chemical mechanical grinder with a 5-month kappa, does not use hard particles (diamonds + 7 '^, but high-pressure liquid or ancient factory particles) to adjust the grinding 塾 1 〇2 surface. Therefore, the second of the present invention = body 20 6 to adjust the grinding table 102 on the table 102, so that the wafer 102 has hard particles falling on the grinding table grinding machine using the hair 3; , Second question. Therefore, 'reducing wafer defects in the chemical mechanical machinery' can adjust the grinding process to improve the yield of wafers, thereby improving the yield of wafers. In summary, the present invention has the following advantages: y: The regulator of the chemical mechanical polishing machine uses high-pressure liquid ί i: ΐ Wither polishing pad 'so you can avoid the conventional regulator can = hard particles will fall off the polishing pad, resulting in wafer defects Case 2. The conditioner of the chemical mechanical polishing machine of the present invention can not only improve the yield of the wafer, but also the structure of the conditioner is not too complicated. Although the present invention has been disclosed above in a preferred embodiment, it is not To limit the invention, anyone skilled in the art, in Departing from the spirit of the invention
