Patent attributes
A package structure includes a circuit substrate, a semiconductor package, first bump structures and second bump structures. The semiconductor package is disposed on the circuit substrate, wherein the semiconductor package includes a center region and side regions surrounding the center region. The first bump structures are disposed on the center region of the semiconductor package and electrically connecting the semiconductor package to the circuit substrate. The second bump structures are disposed on the side regions of the semiconductor package and electrically connecting the semiconductor package to the circuit substrate, wherein the first bump structures and the second bump structures have different heights and different shapes.
