Abstract:
An overlay metrology system may measure a first-layer pattern placement distance between a pattern of device features and a pattern of reference features on a first layer of an overlay target on a sample. The system may further measure, subsequent to fabricating a second layer including at least the pattern of device features and the pattern of reference features, a second-layer pattern placement distance between the pattern of device features and the pattern of reference features on the second layer. The system may further measure a reference overlay based on relative positions of the pattern of reference features on the first layer and the second layer. The system may further determine a device-relevant overlay for the pattern of device-scale features by adjusting the reference overlay with a difference between the first-layer pattern placement distance and the second-layer pattern placement distance.

Claim (Index 16):
The overlay metrology system of  claim 14 , wherein the particle-based imaging system comprises:\n an ion-beam imaging system.
