Patent ID: 8263421

Claim:
A manufacturing method of a display device comprising: forming a gate electrode and a pixel electrode over a substrate having an insulating surface; forming an insulating film over the gate electrode and the pixel electrode; introducing the substrate into a vacuum chamber; forming a lower part of a microcrystalline semiconductor film in a vacuum chamber under a first film formation condition in which glow discharge plasma is generated by superposed application of a first high-frequency power having a frequency with a wavelength of 10 m or longer and a second high-frequency power having a frequency with a wavelength of shorter than 10 m, to an electrode that generates glow discharge plasma; and depositing an upper part of the microcrystalline semiconductor film under a second film formation condition in which at least one of substrate temperature, power, frequency, flow rate of source gas, and degree of vacuum is different from that under the first film formation condition.
