Abstract
A high frequency IC package mainly includes a substrate, a bumped chip, and a plurality of conductive fillers where the substrate has a plurality of bump holes penetrating from the top surface to the bottom surface. The active surface of the chip is attached to the top surface of the substrate in a manner that the bumps are inserted into the bump holes respectively. The conductive fillers are formed in the bump holes to electrically connect the bumps to the circuit layer of the substrate. The high frequency IC package has a shorter electrical path and a thinner package thickness.
