Claim Text:
1. A method for fabricating a package structure, comprising the steps of: providing a substrate having opposite top and bottom surfaces, wherein the substrate has a plurality of conductive pads and a plurality of conductive posts formed therein, the conductive pads are exposed from the bottom surface of the substrate and the conductive posts are electrically connected to the conductive pads and exposed from the top surface of the substrate; forming a conductive layer on the top surface of the substrate; forming a plurality of first conductive bumps and a plurality of second conductive bumps on the conductive layer, wherein the second conductive bumps are higher than the first conductive bumps; removing the conductive layer exposed from the first conductive bumps and the second conductive bumps; and disposing and electrically connecting at least a first electronic element to the first conductive bumps.
