Abstract
A power line layout structure of the semiconductor device may include first through fifth power lines. The first and second power lines may be located at a first layer, and may provide different types of power-supply voltages. The third power line may be located at a second layer disposed at a level different from that of the first layer. The third power line may be coupled to the first power line through a first contact, and may extend in the same direction as the first power line. The fourth power line may be located at the second layer, and may be coupled to the second power line through a second contact. The fourth power line may extend in the same direction as the second power line. The fifth power line may be disposed between the first power line and the second power line in the first layer.

A power line layout structure for a semiconductor device comprising:
- a first power line and a second power line located at a first layer and providing different types of power-supply voltages;
- a third power line located at a second layer disposed at a level different from that of the first layer, the third power line being coupled to the first power line through a first contact and extending in the same direction as the first power line;
- a fourth power line located at the second layer and coupled to the second power line through a second contact, the fourth power line extending in the same direction as the second power line;
- and
- a fifth power line disposed between the first power line and the second power line in the first layer.
A power line layout structure for a semiconductor device comprising:
- two or more first power lines providing the same type of power-supply voltages, the two or more first power lines being disposed at different levels and extending in the same direction, at least one of the two or more first power lines is narrower in width than another first power line disposed at an adjacent level;
- and
- a second power line disposed next to the at least one of the two or more first power lines at the same level as the at least one of the two or more first power lines, the second power line providing a power supply voltage different from those the two or more first power lines provide.
