Abstract:
1. A semiconductor device for use in a radio communication device, comprising: a semiconductor chip including a differential low noise amplifier having a pair of radio signal inputs; a first electrode and a second electrode for the pair of radio signal inputs disposed on a main surface of the semiconductor chip; a chip mounting portion over which the semiconductor chip is mounted; a plurality of leads disposed around the chip mounting portion; a first conductive wire electrically connecting the first electrode and a first lead of the plurality of leads; a second conductive wire electrically connecting the second electrode and a second lead of the plurality of leads; a resin sealing body covering the semiconductor chip, parts of the leads and part of the chip mounting portion, wherein the semiconductor device has a Quad Flat Non-leaded Package (QFN) structure; each of the first and second leads has a first portion and a second portion; the second portion extends inwardly from the first portion toward the chip mounting portion; the first portion is exposed from a back surface of the resin sealing body; the second portion has a thickness smaller than that of the first portion; the second portion is positioned in the inside of the resin sealing body; in a plan view, the second portion extends obliquely from the first portion is wider than the first portion; and the first and second conductive wires are bonded to the second portions of the first and second leads, respectively.
