Abstract
A semiconductor device which has a resistor, a capacitor, and a Schottky diode all formed on a single semiconductor substrate. The capacitor comprises a dielectric region between two metal regions. The resistor comprises an N.sup.+ -type well. The Schottky diode comprises an N-type tub, a metal region in contact with the tub, and an N.sup.+ -type region formed in the N-type tub. The resistor and capacitor are coupled by a metal region which contacts one of the metal regions of the capacitor and the N.sup.+ -type well of the resistor. The resistor and Schottky diode are coupled by a metal region which contacts the N.sup.+ -type well of the resistor and the N.sup.+ -type well of the Schottky diode.
