<p>A spiral inductor having a lower metal line and an upper metal line with an insulating layer interposed therebetween is provided. In the spiral inductor, the lower and upper metal lines are connected to each other through a via contact passing through the insulating layer. The upper metal line spirally turns inward from the periphery to the center, and the lower metal line includes a first lower metal line crossing the upper metal line and disposed to be parallel with another adjacent first lower metal line, and a second lower metal line disposed to be parallel with the upper metal line.</p> |
