Abstract
The resistance of a thin-film resistor is substantially increased by forming the thin-film resistor to line one or more non-conductive trenches. By lining the one or more non-conductive trenches, the overall length of the resistor is increased while still consuming approximately the same surface area as a conventional resistor.
