Methods and systems for monitoring semiconductor fabrication processes are
provided. A system may include a stage configured to support a specimen
and coupled to a measurement device. The measurement device may include
an illumination system and a detection system. The illumination system
and the detection system may be configured such that the system may be
configured to determine multiple properties of the specimen. For example,
the system may be configured to determine multiple properties of a
specimen including, but not limited to, critical dimension and overlay
misregistration. In this manner, a measurement device may perform
multiple optical and/or non-optical metrology and/or inspection
techniques.
