Reduction of annealed-induced wafer defects in dual-damascene copper interconnects

Interconnects in very large scale integration (VLSI) chips are susceptible to failure due to mechanical stress in passivated interconnect lines. These mechanisms play a collective role for intensive research of thermal stability for Cu interconnects reliability in CMOS technologies. This paper prese...

Description
Summary:Interconnects in very large scale integration (VLSI) chips are susceptible to failure due to mechanical stress in passivated interconnect lines. These mechanisms play a collective role for intensive research of thermal stability for Cu interconnects reliability in CMOS technologies. This paper presents capabilities and performance on samples annealed using furnace vs He in situ anneal and in-line technique developed to reduce total defect count. © 2012 Elsevier Ltd.
