Abstract
The present disclosure provides a semiconductor device and a semiconductor layout structure. In the semiconductor device, a guard ring of a first type is arranged on at least one side of a transistor of a second type, and a guard ring of a second type is arranged on at least one side of a transistor of a first type, such that a plurality of signal lines in a first metal layer in the semiconductor layout structure may be arranged between a first power source line and a first ground line. Furthermore, in a second metal layer, a plurality of second power source lines are connected to one first power source line, and a plurality of second ground lines are connected to one first ground line.
