Abstract:
An integrated circuit has a buried insulation layer formed over a semiconductor substrate, and a semiconductor mesa formed over the buried insulation layer. A low resistivity guard ring substantially surrounds the semiconductor mesa and is in contact with the semiconductor substrate. The low resistivity guard ring is grounded and isolates the semiconductor mesa from RF signals.
