The Archer 300 is an overlay metrology system built on the Archer platform. The Archer 300 provides robust overlay registration and CD measurements on various substrates. The Archer 300 supports 300mm wafer sizes.[1]
In semiconductor manufacturing, overlay metrology is performed after lithography and before etch to verify alignment of the new pattern to previous layers. Measurement results are used to feed forward corrections to lithography tools or to monitor process stability.
