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： 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.
