What is CMP
This page is introducing the basic knowledge of CMP processing.
CMP is a processing method that smooths the surface of the product by the synergistic effect of a chemical and mechanical approach. It is widely used mainly in the semiconductor field.
What is CMP
One of the advantages of CMP processing is that the surface roughness can be adjusted at the atomic level.
By rearranging the composition of the slurry (slurry = mixture of solid abrasive grains in a liquid), different substances existing on the same substrate can be polished together, and also it is possible to polish only the selected substances.
This technology is widely used mainly in the semiconductor field.
Examples of some applications are wafers for power devices and MEMS devices, polishing of difficult-to-cut materials such as SiC and GaN.
TDC’s CMP processing
TDC’s “ultra-precision polishing” means not only lap polishing, but also CMP processing

How the CMP process works
Unlike general polishing, CMP processing uses a chemical approach with slurry (suspended free abrasive grains) processing solution and a mechanical approach that uses abrasive grains such as silica, alumina, and zirconia to polish at the same time. By doing so, it refers to a way to make the surface of the product smoother.
Another feature is that the speed and quality of polishing can be improved due to the synergistic effect of each.
It is a technology used for finishing precision equipment such as chemical mechanical flattening of SiC substrates and wafers.
CMP in TDC
CMP processing is a synergistic effect of chemical and mechanical approaches that makes the surface of the product smooth.
Therefore, if you are not familiar with the construction method, you may not be able to perform optimal processing for the product.
TDC can deliver products according to your desired delivery date, and has accumulated unique technological development and know-how in processing, making it possible to handle any shape.
