The surface morphology characterization of electroless nickel immersion gold under bump metallurgy (UBM) using SEM
(American Institute of Physics, 2007-05-09)
This paper presents the surface morphology characterization at each process step in electroless nickel immersion gold (ENIG) deposition using Scanning Electron Microscope (SEM). The characterization start at initial bond ...
