What it is
The Strasbaugh 6 DA 4 is a polisher used in semiconductor manufacturing.[1]
How it works
General reference — not yet source-verifiedA chemical mechanical polisher combines controlled pad motion, slurry chemistry, and applied pressure to remove material from a wafer surface. The process uses both chemical action and mechanical abrasion to reduce topography and produce a flatter surface for later fabrication steps.
Where it fits in the process flow
General reference — not yet source-verifiedCMP is typically used after patterning or deposition steps when a wafer surface must be leveled before subsequent processing. It supports integration between front-end film formation and later lithography or interconnect steps that depend on surface planarity.
Applications
General reference — not yet source-verifiedEquipment of this class is used for wafer planarization and surface finishing across semiconductor process flows, including oxide, metal, and dielectric polishing tasks. It is also used when a process requires uniform removal of material from a substrate rather than simple cleaning or inspection.
