Abstract:
1. A method of manufacturing a semiconductor device having a thin film transistor, comprising; forming a thin film transistor on a substrate, the thin film transistor having a semiconductor layer, a first electrode, a second electrode, a gate electrode, and a gate insulator layer, the semiconductor layer being located between the first electrode and the second electrode, the gate electrode overlapping the semiconductor layer, and the gate insulator layer located between the semiconductor layer and the gate electrode; applying a first liquid material including a first insulating material to form a first applied film over the gate electrode; drying the first applied film at a temperature from 80 to 150 centigrade to form a dried film, the dried film not being completely dried but being partially dried; applying a second liquid material including a second insulating material to form a second applied film on the dried film, the second insulating material being different than the first insulating material; and annealing the second liquid material and the first applied film at a temperature from 300 to 500 centigrade to form an interlayer insulator layer over the gate electrode, the thickness of the insulator layer being not less than 500 nm.
