Abstract: Wafer-level (chip-scale) package semiconductor devices are described that have bump assemblies configured to maintain standoff (bump) height. In an implementation, the wafer-level chip-scale package devices include an integrated circuit chip having an array of bump assemblies disposed over the integrated circuit chip. The array of bump assemblies comprises a plurality of first bump assemblies that include solder bumps composed at least substantially of a solder composition (i.e., do not include a core). The array further includes at least one second bump assembly including a solder bump having a core configured to maintain standoff height of the wafer-level package device.

Abstract: Techniques for forming a wafer level package device are disclosed. In one or more embodiments, the techniques include forming a wafer level lead frame on a carrier wafer and electrically connecting the wafer level lead frame to an active semiconductor wafer. The carrier wafer and the active semiconductor wafer have at least substantially the same coefficients of thermal expansion. The carrier wafer can be removed from the wafer level package device, and a number of connectors can be formed on the wafer level package device. The wafer level package device can be singulated to form chip packages, such as DFN or QFN packages.
