Abstract:
A method of improving the voltage linearity of a semiconductor resistor for use, for example, in integrated circuit manufacture, which linearity is deteriorated by the loss of carriers in the resistor at the vicinity of a junction separating the resistor region from the semiconductor body. The method consists of bombarding the semiconductor to implant therein in the vicinity of the junction neutral ions, such as neon, forming lattice damage. The concentration of implanted ions and lattice damage is so high as to reduce the effective mobility of charge carriers in the region resulting in the improved voltage linearity.
