Abstract
Abstract A semiconductor device includes a square pellet, a gate electrode pad, a drain electrode pad, a pair of source electrode pads, and a source electrode path. The pellet has first and second diagonal lines. The gate electrode pad is arranged on one of two corners located on the first diagonal line on the pellet. The drain electrode pad is arranged on the other of the two corners located on the first diagonal line on the pellet. The pair of source electrode pads are arranged on two corners located on the second diagonal line on the pellet. The source electrode path connects the source electrode pads to each other.
