Abstract

A submicron resistor having negligible parasitic capacitance includes an isolated released beam carried on a single crystal silicon wafer. The resistor is fabricated by defining a resistor region in the substrate, doping the region to produce the desired resistivity, and etching around the region to produce a resistive island. The island is then isolated from the substrate by oxidation, and is released by removing the oxide to produce an isolated, released resistor beam.
