Damascene Copper electroplating for chip interconnections
TL;DR: The challenges of filling trenches and vias with Cu without creating a void or seam are reviewed, and the discovery that electrodeposition can be engineered to give filling performance significantly better than that achievable with conformal step coverage is found.
Damascene copper electroplating for chip interconnections
TL;DR: Damascene copper electroplating for on-chip interconnections, a process that was conceived and developed in the early 1990s, makes it possible to fill submicron trenches and vias with copper without creating a void or a seam and has thus proven superior to other technologies of copper deposition as discussed by the authors.
Journal ArticleDOI
A High Efficiency Electrodeposited Cu2ZnSnS4 Solar Cell
Shafaat Ahmed,Kathleen B. Reuter,Oki Gunawan,Lian Guo,Lubomyr T. Romankiw,Hariklia Deligianni +5 more
TL;DR: In this article, high performance Cu2ZnSnS4 photovoltaic devices are demonstrated using electrodeposition of metal stacks and annealing of a CuZnS precursor in a sulfur atmosphere.
Journal ArticleDOI
The chemistry of additives in damascene copper plating
TL;DR: It is shown that cuprous intermediates near the copper surface affect the overpotential and the kinetics of plating, and the additives regulate the presence of cuprous species on the surface; levelers and suppressors inhibit Cu+ formation, whereas accelerating additives enhance Cu- formation.
Journal ArticleDOI
Electrodeposited Cu2ZnSnSe4 thin film solar cell with 7% power conversion efficiency
Lian Guo,Yu Zhu,Oki Gunawan,Tayfun Gokmen,Vaughn R. Deline,Shafaat Ahmed,Lubomyr T. Romankiw,Hariklia Deligianni +7 more
TL;DR: In this paper, an electrodeposited CZnSnSe4 (CZTSe) photovoltaic material was synthesized by electrodeposition of metal stack precursors followed by selenization.
