WebAug 2, 2012 · Planarization is a flattening or smoothing out of the wafer surface topography by 1) filling in the deep “trench” areas; 2) etching the top surface of an etched structure; 3) filling in via holes; or 4) some combination of these. Planarization modeling is used to map optimal parameters for layer thickness. WebThe process involves a uniform removal of copper and the planarization of surface topography of copper interconnects by dispensing abrasive free etchants to a rotating wafer. The primary process parameters comprise of (a) Physics and chemistry of etchants, and (b) Nature of fluid flow on a spinning wafer.
