Abstract

A cell library intended to be used to form an integrated circuit, this library defining a first cell including a first MOS transistor of minimum dimensions, and a second cell including a second MOS transistor of lower leakage current, wherein the second cell takes up the same surface area as the first cell, and the second MOS transistor has a gate of same length as the gate of the first MOS transistor across at least a first width in its central portion, and of greater length across at least a second width on either side of the central portion.
