Abstract:
1. A resistor structure for an integrated circuit, comprising: a first set of contacts connected between a first area of a semiconductor layer and a first pad of a first conductive layer, wherein the contacts comprise conductive material-filled vias disposed on the first area of the semiconductor layer; a second set of contacts disposed adjacent to the first set of contacts and connected between a second area of the semiconductor layer and a second pad of the first conductive layer, wherein the first pad is electrically isolated from the second pad and the first area is electrically isolated from the second area; a first set of plugs connected between the first pad of the first conductive layer and a first pad of a second conductive layer, wherein the plugs comprise conductive material-filled vias disposed between any two vertically adjacent conductive layers; and a second set of plugs disposed adjacent to the first set of plugs and connected between the second pad of the first conductive layer and a second pad of the second conductive layer, wherein the first set of contacts and the first set of plugs are coupled together to form a first resistor segment, and the second set of contacts and the second set of plugs are coupled together to form a second resistor segment to provide a predetermined resistance for the integrated circuit.
