Abstract :
Deep-silicon etching was applied to an inductor in a 0.25 μm SiGe:C BiCMOS process. Significant increase of quality factor was achieved. Different simulations of the inductor were done with a planar EM simulator. The way how to handle non-homogenous dielectrics in a planar EM simulator is shown. A good agreement between measurement and simulation can be seen. The effect of back side etching is well predicted by EM simulation.
