Patent ID: 8759206

Claim:
A method for manufacturing a semiconductor device, comprising: stacking a first conductive layer having a light-transmitting property and a second conductive layer over a substrate having an insulating surface; forming a first mask over the second conductive layer; etching the first conductive layer to form a first electrode and a second electrode and etching the second conductive layer to form a third conductive layer, by using the first mask; recessing the first mask to form a second mask; etching the third conductive layer by using the second mask to form a first wiring; forming a semiconductor layer that has a light-transmitting property and is electrically connected to the first electrode and the second electrode; forming an insulating layer so as to cover the semiconductor layer; stacking a fourth conductive layer having a light-transmitting property and a fifth conductive layer over the insulating layer; forming a third mask over the fifth conductive layer; etching the fourth conductive layer to form a third electrode and etching the fifth conductive layer to form a sixth conductive layer, by using the third mask; recessing the third mask to form a fourth mask; and etching the sixth conductive layer by using the fourth mask to form a second wiring.
