Patent ID: 7723200

Claim:
A method of forming a resistor, the method comprising: providing a first plurality of layers of different materials between two insulating layers; passing a current pulse through the first plurality of layers for a first predetermined pulse duration to attain a first predetermined temperature to affect a conductivity structure of the first plurality of layers in order to obtain a first predetermined resistance value for the resistor; providing at least one second plurality of layers of different materials substantially identical to the first plurality of layers; passing a current pulse through each of the at least one second plurality of layers for a second predetermined pulse duration to attain a second predetermined temperature to affect a conductivity structure of each second plurality of layers in order to obtain a second predetermined resistance value different from the first predetermined resistance value; and repeating the passing of the current pulses through both of the first plurality of layers and the at least one second plurality of layers until each has attained a desired resistance value.
