Abstract:
1. A method for increasing an electrical resistance of a resistor, comprising the steps of: providing a predetermined target resistance in terms of a value R providing a semiconductor structure that includes the resistor; exposing a fraction F of an exterior surface of a surface layer of the resistor to oxygen-containing particles; and oxidizing a portion of the surface layer by reacting said portion with said oxygen-containing particles, such that an electrical resistance of the resistor is increased, wherein an exterior surface of said portion consists essentially of the fraction F of the exterior surface of the surface layer, and testing the resistor during the oxidizing step to determine whether the electrical resistance of the resistor is within R wherein if during the testing step the electrical resistance of the resistor is determined to not be within R
