ABSTRACT:
Collective transistors in a high-current IC are arranged in the column and row directions on a substrate, with each row having two collective transistors. The collective transistors are connected in a multi-phase half bridge circuit by wiring conductors which extend in the row direction and by a pair of wiring conductors which extend in the column direction. Each wiring conductor in the row direction includes a top conductive layer which is positioned over a first one of the collective transistors in the respective row and a bottom conductive layer which is positioned over the second collective transistor in the respective row, the top and bottom conductive layers being connected to one another through a connecting hole in an interlayer insulation film. One of the wiring conductors which extends in the column direction includes a bottom conductive layer which is positioned above the first collective transistor and the other wiring conductor which extends in the column direction includes a top conductive layer which is positioned over the second collective transistor.
