Optimization of Cu Pillar Bumping Process for Probing Mark in Al Pad
碩士 === 國立高雄大學 === 電機工程學系--先進電子構裝技術產業研發碩士專班 === 102 === Wafer test procedure have 2 types that are pre-bumping and post-bumping. However, pre-bumping induce probing mark in Al pad. The probing mark would impact adhesion issue for wire bounding process. So, Al pad of roughness can effect bump strongth...
