In the semiconductor industry polishing process,the polishing surface of the polishing pad will accumulate the material to be removed from the wafer and the polishing particles in the polishing liquid. These particles will fill up and block the micro-holes on the polishing surface,causing the polishing pad to lose its polishing ability. Therefore, the industry has introduced polishing pad dressers to dress the polishing pads.The polishing pad dresser is pressed on the polishing surface of the polishing pad to generate the ability to remove the particles that fill the micropores on the polishing surface of the polishing pad,remove the particles remaining on the polishing surface, and restore the polishing surface of the polishing pad.Return to a more ideal state.
