Abstract
A transmission line device includes a daisy chain structure composed of at least three daisy chain units arranged periodically and continuously. Each of the daisy chain units includes first, second and third conductive lines, and first and second conductive pillars. The first and second conductive lines at a first layer extend along a first direction and are discontinuously arranged. The third conductive line at a second layer extends along the first direction and is substantially parallel to the first and second conductive lines. The first conductive pillar extends in a second direction. The second direction is different from the first direction. A first part of the first conductive pillar is connected to the first and third conductive lines. The second conductive pillar extends in the second direction. A first part of the second conductive pillar is connected to the second and third conductive lines.
