Patent ID: 8472911

Claim:
A semiconductor device for use in a radio communication device, comprising: a substrate including a top surface, a plurality of wirings formed in the substrate, and a bottom surface opposite to the top surface; a plurality of external terminals formed on the bottom surface of the substrate; a semiconductor chip, including a main surface; a back surface opposite to the main surface, mounted over the top surface of the substrate via a plurality of bump electrodes such that the main surface faces the same direction as the top surface of the substrate, a first low noise amplifier formed on the main surface; a first mixer which receives signals from the first low noise amplifier; a bias circuit; and a plurality of pads formed over the main surface of the semiconductor chip, wherein the bias circuit is coupled to the first low noise amplifier, wherein the plurality of pads includes a first pad electrically coupled to the first low noise amplifier, a plurality of second pads which are electrically coupled to ground voltage level, and wherein the first pad is arranged near the second pads.
