- the present invention relates to an aluminum alloy target, an aluminum alloy wiring film, and a method for manufacturing an aluminum alloy wiring film.
- TFTs thin film transistors
- a low resistance metal such as Al may be used as a wiring material.
- the gate electrode since the gate electrode is formed in the middle of the manufacturing process, it receives a thermal history due to annealing treatment after the gate electrode is formed. Therefore, as the material of the gate electrode, a refractory metal (for example, Mo) having a heat resistance capable of withstanding the heat history is often used (see, for example, Patent Document 1).
- a refractory metal for example, Mo
- a refractory metal such as Mo
- the refractory metal does not have sufficient bending resistance. Therefore, the electrode may break due to bending.
- a refractory metal such as Mo has a higher resistivity than a low resistivity metal such as Al. This can lead to display delays on the display as the size of the display increases.

If the thickness is less than 100 nm, it becomes difficult to reduce the resistance of the gate electrode 13.
