Abstract :
The present paper investigates the sensitivity of on wafer interconnect to the Si CMOS process parameters. In particular the tapered (trapezoid) etching and the conductor surface profile (Rrms) of copper foils are numerically analyzed in order to quantify their effect on the electrical performance of a stripline structure. Line impedance, insertion loss and time signal attenuation are evaluated by means of three dimensional (3D) electromagnetic (EM) simulations. Hammerstad and Jensen analytical model is implemented and results are compared with those coming from the full 3D EM simulation model. Good agreement in the frequency range 0- 50 GHz is observed.
