Abstract
A semiconductor device receives differential input signals, performs predetermined signal processing, and outputs differential output signals. Plural rear surface electrodes, disposed in an m-row, n-column (m and n being integers) matrix form, on a rear surface of the semiconductor device, are formed. The rear surface electrodes for the differential input signals or differential output signals are disposed in rows, 1, 2, m−1, and m, or in columns, 1, 2, n−1, and n, of a matrix. Furthermore, a pair of rear surface electrodes for differential input signals that for a pair, and a pair of rear surface electrodes PAD for differential output signals that form a pair, are respectively disposed so as to be adjacent.
