Patent Classification: ["355", "067000"]

Abstract:
A target formed on a substrate, the target having: an alignment structure; and a metrology structure; wherein the alignment structure comprises structures that are arranged to generate a beat pattern when the alignment structure is illuminated with source radiation. Advantageously, when the target is illuminated, the beat pattern that appears in an image of the target allows the target to be easily identified using a pattern recognition technique.

Claim (Index 20):
A metrology apparatus for measuring a target formed on a substrate, the apparatus comprising:\n a first measurement system configured to illuminate the target with first radiation and detect radiation resulting from scattering of the first radiation from the target; a second measurement system configured to illuminate the target with second radiation and detect radiation resulting from scattering of the second radiation from the target; and a controller configured to:\n detect a position of the alignment structure using the radiation detected by the first measurement system; and \n control the second measurement system to use the detected position of the alignment structure to align a radiation spot of the second radiation onto a desired location within the metrology structure, \n wherein the target is a target according to  claim 1 .
