WebTechniEtch TBR19 is an enabling, fluoride-free aqueous solution, designed to selectively dissolve titanium (Ti) and titanium alloy based (TiN, TiW) barriers for far back end of the line (BEOL) interconnect applications . This high performing metal etchant can significantly reduce undercut. WebAug 14, 2015 · Traditional sputtering TiW/Cu barrier/seed layer was also evaluated as reference. Results showed that electroplated Cu on the ALD TiN layer would reach higher filling ratio than TiW/Cu layer. The diffusion depth of Cu in TiN is similar to that in TiW/Cu.

WebThe UBMs were sputtered TiW/plated copper, electroless plated Ni-P/immersion gold, and electrolytic nickel (used only for solder plating). The nickel was chosen because it reacts slowly, compared to copper or gold, with tin-rich solders. The TiW/Cu used sufficient copper to survive multiple reflows with the tin-rich alloys. WebOct 17, 2024 · The binary alloy of titanium-tungsten (TiW) is an established diffusion barrier for copper metallisation schemes. However, little has been established regarding the chemical state of the TiW/Cu interface or the possible degradation mechanisms of the barrier during annealing.
