摘要： An object is to provide a manufacturing method of a microcrystalline semiconductor film with favorable quality over a large-area substrate. After forming a gate insulating film over a gate electrode, in order to improve quality of a microcrystalline semiconductor film formed in an initial stage, glow discharge plasma is generated by supplying high-frequency powers with different frequencies, and a lower part of the film near an interface with the gate insulating film is formed under a first film formation condition, which is low in film formation rate but results in a good quality film. Thereafter, an upper part of the film is deposited under a second film formation condition with higher film formation rate, and further, a buffer layer is stacked on the microcrystalline semiconductor film.

摘要： After a gate insulating film is formed over a gate electrode, in order to improve the quality of a microcrystalline semiconductor film which is formed in an early stage of deposition, a film near an interface with the gate insulating film is formed under a first deposition condition in which a deposition rate is low but the quality of a film to be formed is high, and then, a film is further deposited under a second deposition condition in which a deposition rate is high. Then, a buffer layer is formed to be in contact with the microcrystalline semiconductor film. Further, plasma treatment with a rare gas such as argon or hydrogen plasma treatment is performed before formation of the film under the first deposition condition for removing adsorbed water on a substrate.

摘要： To provide a photoelectric conversion device with improved photoelectric conversion characteristics and cost competitiveness. A photoelectric conversion device including a semiconductor junction has a semiconductor layer in which a needle-like crystal is made to grow over an impurity semiconductor layer. The impurity semiconductor layer is formed of a microcrystalline semiconductor and includes an impurity imparting one conductivity type. An amorphous semiconductor layer is deposited on a microcrystalline semiconductor layer by setting the flow rate of a dilution gas (typically silane) to 1 time to 6 times the flow rate of a semiconductor source gas (typically hydrogen) at the time of deposition. Thus, a crystal with a three-dimensional shape tapered in a direction of the deposition of a film, i.e., in a direction from the microcrystalline semiconductor layer to the amorphous semiconductor layer is made to grow.

摘要： When semi-amorphous TFTs are used for forming a signal line driver circuit and a pixel, a large amplitude is required for driving the pixel, and a large power supply voltage is thus needed. On the other hand, when a shift register is made up of transistors having a single conductivity, a bootstrap circuit is required, and a voltage over a power supply is applied to a specific element. Therefore, not both the driving amplitude and the reliability can be achieved with a single power supply. According to the invention, a level shifter having a single conductivity is provided to solve such a problem.
摘要翻译：当使用半非晶TFT来形成信号线驱动电路和像素时，驱动像素需要大的幅度，因此需要大的电源电压。另一方面，当移位寄存器由具有单一导电性的晶体管构成时，需要自举电路，并且将电源上的电压施加到特定元件。因此，不能通过单个电源实现驱动振幅和可靠性。根据本发明，提供具有单一电导率的电平移位器来解决这个问题。
