Method of making a high resistance drain junction resistor in a SRAM

摘要

An improved SRAM resistor structure having implanted therein ions of an material in the surface layer of a drain junction region juxtaposed to an overlying metal contact layer providing the benefits of high resistance, low energy consumption, a single ion implantation step in an easily controlled process while producing a precise resistance desired and a method of making the SRAM resistor structure.
