Typical CMP tools, such as the ones seen on the right, consist of rotating an extremely flat plate which is covered by a pad. The wafer that is being polished is mounted upside-down in a carrier/spindle on a backing film. The retaining ring (Figure 1) keeps the wafer in the correct horizontal position. During the process of loading and unloading the wafer onto the tool, the wafer is held by vacuum by the carrier to prevent unwanted particles from building up on the wafer sur… WebMar 12, 2015 · RESULTS4.1 Graphical Presentation removalrates over 37sites eachwafer. organizedso threeboxes within each threewafers conditionwere polished.
