Abstract
An integrated circuit package structure includes a circuit board, an integrated circuit die and a conductive stair structure. The circuit has an upper surface. The integrated circuit die is located on the upper surface of the circuit board. The conductive stair structure is located on the upper surface of the circuit board. The conductive stair structure includes steps along a first direction substantially perpendicular to the upper surface of the circuit board. The steps have different heights relative to the upper surface of the circuit board.
