A method for trimming a diffused or implanted resistor located within an integrated circuit is disclosed. This technique for trimming a resistor requires the use of high current pulses and geometric shaped metal contacts. The current pulses react with the electropositive metal atoms in the thin film conductor and cause the metal atoms to migrate to another location, thus altering the value of the resistor by progressively decreasing the conductivity of the resistor.
