US Patent 9372206 Testing of semiconductor chips with microbumps

A package includes a semiconductor chip. The semiconductor chip includes a test pad, and a plurality of microbump pads, wherein each microbump pad of the plurality of microbump pads is electrically connected to the test pad. The package further includes a substrate; and a plurality of microbumps configured to electrically connect the semiconductor chip to the substrate, wherein each microbump of the plurality of microbumps is electrically connected to a corresponding microbump pad of the plurality of microbump pads. The package further includes a package substrate, wherein the package substrate comprises a bump pad, wherein an area of the bump pad is greater than a combined area of the test pad and the plurality of microbump pads. The package further includes a bump configured to electrically connect the substrate to the package substrate.
