Abstract
A device and method for evaluating reliability of a semiconductor chip structure built by a manufacturing process includes a test structure built in accordance with a manufacturing process. The test structure is thermal cycled and the yield of the test structure is measured. The reliability of the semiconductor chip structure built by the manufacturing process is evaluated based on the yield performance before the thermal cycling.
