Structure for electrically tunable resistor

A design structure embodied in a non-transitory machine readable medium for designing, manufacturing, or testing an integrated circuit, the design structure is executable on a computer to provide elements of the integrated circuit that comprise:

• a resistor including:
• a first resistive layer;
• at least one second resistive layer;
• and
• an intermediate interdiffused layer of the first resistive layer and the at least one second resistive layer, the intermediate interdiffused layer extending substantially between the entire length of the first resistive layer and the at least one second resistive layer;
• and
• a tuner for passing a current pulse through the first resistive layer and the at least one second resistive layers to affect a conductivity structure of the first resistive layer and the at least one second resistive layer in order to obtain a first predetermined resistance value for the resistor, wherein the tuner includes a tuning and application circuit, decode circuitry to select one of the resistive layers in the resistor for tuning, and a fine current tuning circuitry to further tune one of the resistive layers selected by the decode circuitry,
• wherein the design structure embodied in the non-transitory machine readable medium is in a data format used for an exchange of layout data of the integrated circuit.
