Role of the Oxidation State in Cobalt Chemical Mechanical Planarization

ABSTRACT Cobalt (Co) is a promising next‐generation contact metal to replace tungsten for the system‐large‐scale integration devices beyond the 5 nm technology node due to its low resistivity and high gap‐filling capability at high aspect ratios. To complete Co metallization, surface roughness contr...
