Latest Patents

Yu-Ching Lee's latest patents revolve around a bumping process and bump structure. This process involves forming a passivation layer with a planarized surface that covers a pad on a substrate. A hole is then created to expose the contact surface of the pad, followed by the formation of a bump on both the contact surface and the planarized surface. The planarized surface provides a larger effective area for pressing, which minimizes the pad and enhances the mechanical strength at its periphery. This innovation offers greater selection flexibility for anisotropic conductive film, reduces the chances of short circuits and current leakage within the bump gap, and ultimately increases the yield of the pressing process along with the conductive quality of the bump.
