Abstract

A power chip includes: a first power switch, formed in a wafer region and having a first and a second metal electrodes; a second power switch, formed in the wafer region and having a third and a fourth metal electrodes, wherein the first and second power switches respectively constitute an upper bridge arm and a lower bridge arm of a bridge circuit, and the first and second power switches are alternately arranged along a first direction; and a metal region, at least including a first metal layer, a second metal layer and a third metal layer that are stacked, each metal layer including a first to a third strip electrodes, and strip electrodes with the same voltage potential in two adjacent metal layers are electrically coupled, wherein a routing direction of the strip electrode in the first metal layer is substantially perpendicular to the first direction.
