The characterization of Al Bond pad surface treatment in Electroless Nickel Immersion Gold (ENIG) deposition
Mohd Khairuddin, Md Arshad; Azman, Jalar; Ibrahim, Ahmad; Ghazali, Omar (Science Publications, 2007)This study reports a number of experiments that were designed to characterize aluminum bond pad surfaces prior to electroless nickel immersion gold (ENIG). In the ENIG process, aluminum bond pads need special treatment ... -

The effects of multiple zincation process on Aluminum Bond Pad surface for Electroless Nickel Immersion Gold deposition
Mohd Khairuddin, Md Arshad; Ibrahim, Ahmad; Azman, Jalar; Ghazali, Omar; Uda, Hashim (American Society of Mechanical Engineers (ASME), 2006-09)This paper reports the effects of a multiple zincation processon the Al bond pad surface prior to electroless nickel immersion gold deposition. The study of multiple zincation comprises the surface topogtaphy and morphology ... -
The surface characteristics of under bump metallurgy (UBM) in electroless nickel immersion gold (ENIG) deposition
Mohd Khairuddin, Md Arshad; Ibrahim, Ahmad; Azman, Jalar; Ghazali, Omar (Elsevier Science, 2006)This paper discusses on the surface characteristics of each of the seven set-up process steps prior completion of under bump metallurgy (UBM) deposition. The Atomic Force Microscopy (AFM) and Scanning Electron Microscopy ...
