UMass Amherst researchers have developed a laser-based holographic alignment method that could revolutionize overlay accuracy in semiconductor manufacturing, though its industrial adoption may hinge ...

Laser alignment is tricky, but we’ve seen a few other solutions out there. For a more classic mechanism that traces the actual beam path with burn marks, have a look at [Stephen’s] method.

The approach uses lasers and holograms to detect misalignments as small as 0.017 nanometers. Researchers at the University of ...

Innovative laser alignment methods enable precise imaging of biomolecules, advancing single-particle diffraction techniques ...
