SEMICONDUCTOR DEVICE PACKAGE WITH BUMP OVERLYING A POLYMER LAYER |
摘要 |
A semiconductor device package, for example a flip-chip package, having a solder bump mounted above a polymer layer for use in flip-chip mounting of a semiconductor device to a circuit board. A polymer layer such as polybenzoxazole is formed overlying a wafer passivation layer. Solder bumps are attached to an under-bump metallization layer and electrically coupled to conductive bond pads exposed by openings in the wafer passivation layer.
