Claim 0:
1. A package structure for a power supply module, the package structure comprising:
a) a die and a capacitive element that are separated from each other and arranged on different horizontal planes with different heights along a vertical direction of the package structure, wherein the die is arranged on one surface of a ground layer;
b) a plurality of connection structures that connect to the die and to the capacitive element;
c) wherein a current loop comprising at least two parallel current paths on different horizontal planes with different heights along the vertical direction of the package structure is formed;
d) wherein the current loop passes through the die, the capacitive element, and the plurality of connection structures, and directions of currents of the two parallel current paths are at least partially opposite to each other in order to decrease electromagnetic interference;
e) wherein the two parallel current paths comprise a first current path that flows through the capacitive element, and a second current path that flows through the die;
f) wherein an input voltage pad is connected to corresponding contact pads on an active surface of the die through corresponding conductive bumps, and is connected to a positive terminal of the capacitive element through corresponding of the plurality of connection structures; and
g) wherein a ground potential pad is connected to corresponding contact pads on the active surface of the die through corresponding conductive bumps, and to the ground layer through corresponding of the plurality of connection structures.
