Abstract
A resistor body is separated from a doped well in a substrate by a resistor dielectric material layer. The doped well is defined by at least one doped region and can include a dopant gradient in the doped well to reduce parasitic capacitance of the resistor structure while retaining heat dissipation properties of the substrate. The resistor body is formed in a cavity in a dielectric layer deposited on the substrate, which deposition can be part of a concurrent fabrication, such as part of forming shallow trench isolations, and the cavity can be lined with the resistor dielectric material.
