Abstract:
1. A semiconductor device having a rectangular semiconductor element mounted on a substrate formed with an external input terminal, an external output terminal, and a plurality of wiring patterns connected to each of the external input terminal and the external output terminal, wherein, the semiconductor element comprises: a plurality of first electrodes formed along a first edge of a surface thereof; a plurality of second electrodes formed along an edge opposite to the first edge of the surface; a plurality of third electrodes formed in the neighborhood of a functional block; and an internal wiring for connecting the first electrodes and the third electrodes, and the substrate comprises: a first wiring pattern for connecting the external input terminal and the first electrodes; a second wiring pattern for connecting the external output terminal and the second electrodes; and a third wiring pattern for connecting the first electrodes and the third electrodes, wherein: the semiconductor element further comprises a signal input electrode formed in the neighborhood of the first electrodes and along the first edge; the substrate further comprises an input signal wiring pattern for connecting the signal input electrode and the external input terminal; the first wiring pattern and the input signal wiring pattern are disposed in line; the input signal wiring pattern is disposed at an outer side of the first wiring pattern; the signal input electrode is disposed closer to a central part of the first edge than the first electrodes; the input signal wiring pattern connects to the signal input electrode via an outer side of the first electrodes as viewed from the first edge; and the third wiring pattern detours around the input signal wiring pattern and connects to the third electrodes.
