interesting...... the best of both worlds

but they're only making digital logic and RF transistors with it.

There are a couple of mixed signal SiGe processes out there; and I think somebody (from memory TI) is even shipping some op-amps that use it. A quick google shows that the THS4304, OPA211 and OPA827 all use SiGe.

The new degree of freedom that it gives is to combine a change in doping with a change in bandgap; the main advantage is seen in HBT (Heterojunction Bipolar Transistors), where the SiGe is used in the base.
