What it is
How it works
General reference — not yet source-verifiedIn a CMP polisher, a wafer is mounted on a carrier head and pressed face-down against a rotating polishing platen covered with a pad.
A chemically active slurry is dispensed onto the pad; the chemistry weakens the surface layer while the abrasive particles mechanically remove material.
Where it fits in the process flow
General reference — not yet source-verifiedCMP is used after thin-film deposition steps, such as dielectric or metal deposition, to planarize the surface before subsequent lithography.
The planarized surface enables tighter depth-of-focus for lithography and improves step coverage in subsequent layers.
Applications
General reference — not yet source-verifiedCommon applications of CMP include planarization of interlayer dielectrics, copper damascene processing for interconnect metallization, and shallow trench isolation.
CMP is also used in the fabrication of MEMS devices and compound semiconductor substrates.
