Abstract
A method and system for determining an operating voltage for a semiconductor device. A first plurality of lifetimes may be determined for a first plurality of semiconductor device where the polysilicon lines in each of the first plurality of semiconductor devices have the same total area but different peripheral lengths. A second plurality of lifetimes may be determined for a second plurality of semiconductor devices where the polysilicon lines in each of the second semiconductor device have the same peripheral length but different total areas. Further, the STI structures (used to separate one or more active areas) in each of the second plurality of semiconductor devices may have the same length as the STI structures (used to separate one or more active areas) in each of the first plurality of semiconductor devices. The operating voltage may be determined based on the first and second plurality of lifetimes.
