25nm vias
Current 65nm technologies use
copper interconnects with dimensions of 90nm
Our laboratory is fabricating
interconnect structures with 30nm dimension
Three generations
beyond current technologies: Questions….
Will the resistivity
of copper be limited by mesoscopic scattering
effects?
Can copper grains grow in sub-50nm
structures?
Will eltromigration
reliability be degraded?
Will stress gradients exceed the yield stress of
the interconnect layers?
