摘要
A lateral power semiconductor device with a metal interconnect layout for low on-resistance. The metal interconnect layout includes first, second, and third metal layers, each of which include source bars and drain bars. Source bars in the first, second, and third metal layers are electrically connected. Drain bars in the first, second, and third metal layers are electrically connected. In one embodiment, the first and second metal layers are parallel, and the third metal layer is perpendicular to the first and second metal layers. In another embodiment, the first and third metal layer are parallel, and the second metal layer is perpendicular to the first and third metal layers. A nonconductive layer ensures solder bumps electrically connect to only source bars or only drain bars. As a result, a plurality of available pathways exists and enables current to take any of the plurality of available pathways.
