ABSTRACT:
A method for operating an integrated circuit tester information processing system includes measuring current information from test structures for an integrated circuit having dual stress liners; selecting currents from the current information or stored current information; deriving a scaling factor with the currents for a stress contribution based on an active area of a circuit element in the integrated circuit; and correlating the stress contribution with the integrated circuit.
