Patent ID: 7196782

Claim:
A system configured to determine at least two properties of a specimen during use, comprising: a stage configured to support the specimen during use; a first measurement device coupled to the stage, wherein the first measurement device is configured to generate one or more output signals responsive to at least one thin film characteristic of the specimen during use, and wherein the first measurement device comprises an X-ray reflectometer; a second measurement device coupled to the stage, wherein the second measurement device is configured to generate one or more output signals responsive to at least one electrical property of the specimen during use, wherein the second measurement device comprises a device configured to deposit a charge on an upper surface of the specimen, and wherein the second measurement device is further configured to anneal the specimen to drive metal contamination into a dielectric material formed on the specimen and to measure a tunneling voltage of the dielectric material subsequent to annealing of the specimen; and a processor coupled to the first measurement device and the second measurement device, wherein the processor is configured to determine the at least one thin film characteristic from the one or more output signals of the first measurement device during use and to determine the at least one electrical property of the specimen from the one or more output signals of the second measurement device during use, wherein the at least one electrical property comprises the metal contamination of the dielectric material, and wherein the processor is further configured to determine the metal contamination as a function of the measured tunneling voltage.
