Abstract
This description relates to an integrated circuit device including a conductive pillar formed over a substrate. The conductive pillar has a sidewall surface and a top surface. The integrated circuit device further includes an under-bump-metallurgy (UBM) layer between the substrate and the conductive pillar. The UBM layer has a surface region. The integrated circuit device further includes a protection structure on the sidewall surface of the conductive pillar and the surface region of the UBM layer. The protection structure is formed of a non-metal material.
