[MOVED] metal line reistance

[Eman kamel]

hi every one
i calculate the interconnect resistance by unit length for 45 nm technology
by the equation

Rinterconnect = Resistivity/(Thickness * Width)
i am using Metal Resistivity value 1.688e-2 ohm.micro meter
Thickness = 0.280 micro meter
Width =140 micrometer
i got R interconnect 0.0004 ohm/micro meter, while i found it in litreature to be in range of .04 ohm /micro meter
what do you think make this difference??
thanks in advance
Eman

can you check the all values in the literature also once and cehck if they are also using the same as u are using.. ?

140um is not interconnect, that's a fat-@ss power bus
or something pad-scale. Maybe you wanted nm?
