Claim Text:
1. An integrated circuit (IC) with a selective temperature coefficient of resistance (TCR), the IC comprising, a first resistor having a first trench in a dielectric layer, the first trench having a first width; a second resistor having a second trench in the dielectric layer, the second trench having a second width not equal to the first width; a first conductive layer coating at least a portion of each of the first trench and the second trench, the first conductive layer having a first TCR; and a second conductive layer coating at least a portion of the first conductive layer in each of the first trench and the second trench, the second conductive layer having a second TCR, wherein the second TCR is not equal to the first TCR, and wherein the TCR of the IC is selected based on a dimension of the first trench, a dimension of the second trench, a thickness of the first conductive layer, and a thickness of the second conductive layer.
