Abstract:
1. A method for manufacturing a semiconductor device comprising: forming a first conductive layer and a second conductive layer over a substrate; forming a first insulating layer over the first conductive layer and the second conductive layer; forming an oxide semiconductor layer over the first insulating layer, wherein the oxide semiconductor layer continuously extends over the first conductive layer and the second conductive layer; forming a second insulating layer over the oxide semiconductor layer; forming a third conductive layer and a fourth conductive layer over the second insulating layer, wherein the third conductive layer, the first conductive layer and the oxide semiconductor layer overlap with each other; wherein the fourth conductive layer, the second conductive layer and the oxide semiconductor layer overlap with each other; wherein the third conductive layer contacts the first conductive layer through openings of the first insulating layer and the second insulating layer; and wherein the fourth conductive layer contacts the second conductive layer through openings of the first insulating layer and the second insulating layer.
