Provisional entry — research in progress
This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
What it is
It is a Strasbaugh-branded polisher in the 6 UR 4 spindle configuration.[1]
How it works
General reference — not yet source-verifiedA chemical mechanical polisher removes material by combining controlled pad motion, slurry action, and downward force on the workpiece surface. The process uses both chemical interaction and mechanical abrasion to reduce topography and improve flatness.
A multi-spindle polishing tool can process more than one workpiece position in parallel, using separate carrier heads or spindle stations to apply and control polishing action.
Where it fits in the process flow
General reference — not yet source-verifiedCMP is used after deposition, etch, and other patterning steps when a wafer surface must be planarized before subsequent lithography or interconnect processing.
Polishing equipment of this class is positioned in the wafer-finishing portion of the fab flow, where it supports surface planarity and interface preparation.
Applications
General reference — not yet source-verifiedThis class of equipment is used for wafer planarization, interlayer dielectric polishing, metal planarization, and other surface-finishing steps in semiconductor fabrication.
