Redefining Chemical Mechanical Planarization (CMP)

LET US HELP

What is chemical mechanical planarization (CMP)?

CMP (or chemical mechanical polishing) is when semiconductor wafers undergo repeated polishing and planarisation during fabrication to ensure that the wafer surface is flat and free of extraneous material before subsequent layer processing. This wafer fabrication process uses a combination of a textured hard or soft CMP pad, a CMP pad conditioner and a specialised slurry to polish the wafer.

As the CMP pad is used over time, it must be regularly conditioned with a polishing pad conditioner to maintain consistent polishing performance. CMP pad conditioners can be made of hard or soft materials, and they can be designed with a range of sizes, textures and features to condition different types of pads. Integrated optimisation of pad, slurry and conditioner is increasingly necessary to deliver the required CMP performance at advanced nodes.
