Claim 3:
4. The method of claim 1, further comprising:
forming a first insulation layer covering the semiconductor layer before forming the first conductive line;
forming a second insulation layer covering the first conductive line before forming the second conductive line;
forming a third insulation layer covering the second conductive line;
forming a first contact hole passing through the first insulation layer, the second insulation layer, and the third insulation layer to expose a portion of the semiconductor layer, and a second contact hole passing through the third insulation layer to expose a portion of the second conductive line; and
forming a third conductive line on the third insulation layer, the third conductive line filling the first contact hole and the second contact hole.
