ABSTRACT:
A method of forming a resistor from semiconductive material includes, a) providing a substrate; b) providing a layer of semiconductive material over the substrate; c) providing a pair of openings into the semiconductive material layer; d) plugging the pair of openings with an electrically conductive material to define a pair of electrically conductive pillars within the semiconductive material, the pair of pillars having semiconductive material extending therebetween to provide a resistor construction; and e) providing a conductive node to each of the electrically conductive pillars. An integrated circuit incorporating a resistor construction includes, i) a layer of semiconductive material; ii) a pair of electrically conductive pillars provided within the semiconductive material layer, the pair of pillars being separated from one another and thereby having a mass of the semiconductive material extending therebetween; and iii) an electrically conductive node in electrical connection with each of the respective conductive pillars. Alternately, a resistor is provided within a semiconductive substrate using different concentration diffusion regions.
