Abstract:
An under-bump metallization (UBM) structure for a semiconductor device is provided. The UBM structure has a center portion and extensions extending out from the center portion. The extensions may have any suitable shape, including a quadrangle, a triangle, a circle, a fan, a fan with extensions, or a modified quadrangle having a curved surface. Adjacent UBM structures may have the respective extensions aligned or rotated relative to each other. Flux may be applied to a portion of the extensions to allow an overlying conductive bump to adhere to a part of the extensions.
