Abstract
Different threshold voltages of transistors of the same conductivity type in a complex integrated circuit may be adjusted on the basis of different Miller capacitances, which may be accomplished by appropriately adapting a spacer width and/or performing a tilted extension implantation. Thus, efficient process strategies may be available to controllably adjust the Miller capacitance, thereby providing enhanced transistor performance of low threshold transistors while not unduly contributing to process complexity compared to conventional approaches in which threshold voltage values may be adjusted on the basis of complex halo and well doping regimes.
