Abstract
A switch capable of decreasing parasitic inductance includes: a semiconductor device, a first top metal line, and a second top metal line. The second top metal line electrically connects a power supply input end and a current inflow end of the semiconductor device, wherein a first part of the first top metal line is arranged in parallel and adjacent to a second part of the second top metal line. When the semiconductor device is in an ON operation, an input current outflows from the power supply input end, and is divided into a first current and a second current. When the first current and the second current flow through the first part and the second part respectively, the first current and the second current flow opposite to each other, to reduce an total parasitic inductance of the first top metal line and the second top metal line.
