Reasons from nucleation and growth modes, film stress, interfacial adhesion, and conformality across topography through spectroscopic ellipsometry, XRR, Stoney wafer-curvature, XPS/RBS, and standards like ASTM E2244 and ISO 9211 while treating columnar porosity, barrier pinholes, reactive-sputter hysteresis drift, and uncalibrated-QCM thickness error as first-class failure modes.
