The Current Status and Forecast for the 450 mm CMP Equipment

The paper analyze the current status and trend of the consumable, then alleging the urgently for developing the 450mm wafer's CMP tool and its technology;Basing on the viewpoint which above mentioned, the paper forecasts the 450mm CMP tools will adopt integrated technology、Multi-zone back pressure control technology、pad conditioner technology、endpoint detection technology、post CMP cleaning technology, then analyze each technology specialty. At last, the paperindicate the wafer fabrication compete drastically and invest continually in the near future, which must make the 450mm wafer's CMP tool break through.
