Disclosed is a technique for selectively replacing diffused resistors with ion-implanted resistors in those circuit functions where the absolute values do not set critical input or output interface conditions (levels, impedance, etc.). This provides fast turn-around time for satisfying a demand for semiconductor chips having similar functional characteristics but different performance and power specifications.
