Abstract
A thin film integrated circuit resistor is disclosed that is substantially linear at applied voltages greater than 100 volts. The integrated circuit resistor comprises a substrate, a plurality of resistive blocks electrically connected in series, a shield associated with each resistive block, and passivation means for isolating the substrate from the resistive blocks and the shields, and for isolating the shields from the resistive blocks except where they are electrically connected. Each shield substantially surrounds its associated resistive block with conductive material, and each shield is electrically connected to its resistive block such that each shield is at a potential of some point along the length of its associated resistive block.
