Abstract
Superconformal filling of fine trenches during electrodeposition of copper is described. Copper electrodeposition was accomplished durectly on a ruthenium layer. The ruthenium layer, as well as a titanium layer to promote adhesion, was evaporated on patterned silicon oxide. The electrolyte used was previously shown to yield superconformal feature filling on copper seeded features.Citation
