View source notes and limits
The manufacturer describes tracking film stress or stress-thickness product from substrate curvature during deposition and thermal processing.
Requires optical access and substrate and film-thickness data. It does not show that one thin-film formula can uniquely recover each layer's stress in patterned multilayer RDL.

The official information lists warpage, flatness and thermal-warpage measurement with heating equipment.
Topography measurement is not film-stress identification. Confirm a common reference, support and temperature before and after each step.
