How can a layer-by-layer stress budget guide film-process and thickness comparisons, rather than letting overall package warpage or carrier flattening obscure film stress?
Provide process-step curvature and film-thickness data to confirm whether the added film's contribution can be separated.
How can a layer-by-layer stress budget guide film-process and thickness comparisons, rather than letting overall package warpage or carrier flattening obscure film stress?
Process-step curvature differences with a common reference and single-layer coupon controls
Check film-stress inversion assumptions first, then validate with a multilayer model and samples not used for fitting
