Abstract :
In this paper, coplanar waveguide (CPW) lines are measured up to 110 GHz to characterize 8000 Ω-cm, 15 Ω-cm and 0.015 Ω-cm silicon substrates. The characteristic impedance and attenuation constant for the three substrates are compared and analyzed. The effects of the conductor surface roughness are investigated. The attenuation as a function of high-low doping profile has been investigated for 8000 Ω-cm and 15 Ω-cm substrates. Based on the simulation results, a thin layer of high doping concentration is shown to dominate the attenuation.
