Semiconductor layout structure

The invention discloses a semiconductor layout structure. The semiconductor layout structure comprises at least one first signal line and a pair of low-power supply potential lines, wherein the first signal line and the low-power supply potential lines extend along a first direction, the low-power supply potential lines are arranged along a second direction, the first direction and the second direction are perpendicular to each other, and more importantly, the low-supply potential lines are formed at two opposite sides of the first signal line. 本发明公开种半导体布局结构，其包含有至少第信号线，以及对低电源电位线。该第信号线与该等低电源电位线都沿第方向延伸，且该等低电源电位线沿第二方向排列，而第方向与该第二方向彼此垂直。更重要的是，该等低电源电位线形成于该第信号线的相对两侧。
