ABSTRACT:
An integrated circuit comprises a resistor that is formed by doping a semiconductor region that is defined by a layer, typically polysilicon, that also defines the gate electrode of field effect transistors in the integrated circuit. The well-controlled linewidth of features defined in this layer provides for tight resistor tolerance, and also allows the value of the resistor to track changes in other features defined by this layer.
