  • Abstract
    Describes process characterization techniques and key structural dependencies of chemical-mechanical polishing (CMP) planarization. Also presented are a closed-solution model for simple analysis and a differential model for more complex analysis of CMP planarization and its pattern and polishing pad dependencies. The modelling and characterization give insights into and quantify the effects of `down´ area dimensions, `up´ area patterning, and feature step heights. Differentially modelled results predict corner-rounding and, in doing so, suggest a mechanism
