Semiconductor having protective lines
A semiconductor device includes a signal transmission line extending in a first direction; an outer protective line extending in a substantially identical direction as the first direction and spaced apart from the signal transmission line by a predetermined distance along a second direction which is substantially perpendicular to the first direction; and an inner protective line, disposed between the outer protective line and the signal transmission line, and intermittently extending substantially in parallel with said signal transmission line and outer protective line.

a signal transmission line extending in a first direction;
a first outer protective line and a second outer protective line extending in a substantially identical direction as the first direction, spaced apart from the signal transmission line by a predetermined distance along a second direction which is substantially perpendicular to the first direction and symmetrically disposed on both sides of the signal transmission line;
a first inner protective line, disposed between the first outer protective line and the signal transmission line, and intermittently extending substantially in parallel with the signal transmission line and the first outer protective line; and
a second inner protective line, disposed between the second outer protective line and the signal transmission line, and intermittently extending substantially in parallel with the signal transmission line and the second outer protective line.
