ABSTRACT:
A method of measuring a damaged structure formed on a semiconductor wafer using optical metrology includes directing an incident beam on the damaged structure. A diffracted beam is received from the damaged structure. The received diffracted beam is processed to determine a profile of an undamaged portion of the damaged structure and to measure an amount of dielectric damage of the damaged structure.
