Abstract:
1. A semiconductor sensor reliability system, comprising: a plurality of sensors positioned on a plurality of functional blocks, wherein each of the plurality of functional blocks has at least one sensor, wherein each of the plurality of sensors models a behavior of the location with respect to aging of the location in which it is positioned and communicates real-time aging-related performance data regarding the location over a network, wherein each of the plurality of sensors is selected to have an independent optimal sensitivity based on its location, the optimal sensitivity determined according to sensing range and timing, wherein at least one of the plurality of sensors is coupled directly atop a boundary between functional blocks at a connection point to collect sensed data of variations and a behavior of the boundary, and wherein the at least one of the plurality of sensors is positioned at the connection point between functional blocks to collect sensed data about lithographic limits and gate perimeter density at the connection point.
