Interconnect R/C Notes
As we scale down in technology, metal cross section becomes more square
- Cannot neglect fringing capacitance
Technology scaling by alpha (0.8u to 0.4u, alpha = 0.8/0.4 = 2)
- Rnew = (rho/t)/alpha * [( L/alpha ) * (W/alpha)] Rnew = alpha * Rold (‘t’ is metal thickness, ‘rho’ is resistivity)
