CETR – Tabletop CMP / eCMP System
CETR is the worldwide leading tribology equipment manufacturer, their most updated model eCP-4 is worldwide unique tabletop type CMP machine which can operate both CMP & eCMP mode. The machine can widely use for research & development of CMP, eCMP processes and the related consumables. The computerized real-time motor-control and data-acquisition allows for a repeatable CMP process with crucial process parameters monitored and analyzed in-situ, real-time:
- Dynamic coefficient of friction between both wafer-pad and conditioner-pad, changes of which allow for evaluation of material removal rate and non-uniformity of polishing,
- In-situ monitoring of current and voltage during eCMP mode,
- Energy and peaks of contact high-frequency acoustic emission, which allow for detection evaluation of polishing intensity and detection of micro-scratches and delamination,
- Process temperature in the slurry and on the pad,
- Pad wear during conditioning and/or polishing.
