Granted: 2000-07-11
Abstract: In order to produce an integrated CMOS circuit, a dielectric layer (22) and a silicon layer (23) are applied to a substrate (21). During the formation of insulation structures (26) which insulate neignbouring active regions in the substrate (21), the silicon layer (23) is structured in such a way that is comprises separate subregions which are subsequently doped differently. By full-surface deposition of an electrically conductive layer and common structuring of the electrically conductive layer and the structured silicon layer, differently doped gate electrodes (215, 216) and a metallization plane (217), by which the gate electrodes (215, 216) are electrically connected, are formed. Division of the silicon layer before doping prevents lateral dopant diffusion.
