Abstract

The present disclosure provides an apparatus for manufacturing a semiconductor structure. The apparatus includes a stage, an optical transceiver over the stage, configured to obtain a first profile of a first surface of a substrate, an acoustic transceiver over the stage, configured to obtain a second profile of a top surface of a photo-sensitive layer over the substrate, wherein the stage is adapted to be displaced based on the first profile and the second profile.
