    摘要: A semiconductor device in which a semiconductor layer is formed over a gate electrode with a large aspect ratio, thereby obtaining a channel length of a transistor which hardly causes a short-channel effect even when the transistor is miniaturized. A lower electrode is provided under the gate electrode with an insulating layer provided therebetween so that the electrode overlaps with the semiconductor layer. A potential (electric field) of the lower electrode imparts a conductivity type to the semiconductor layer overlapping with the lower electrode, so that a source region and a drain region are formed in the semiconductor layer. The gate electrode serves as a shield, so that a region in the semiconductor layer, which faces the gate electrode with the gate insulating layer provided therebetween, is not influenced by the electric field from the lower electrode.

    摘要: A method for manufacturing a semiconductor device such as a thin film transistor using a crystal silicon film is provided. The crystal silicon film is obtained by selectively forming films, particles or clusters containing nickel, iron, cobalt, ruthenium, rhodium, paradium, osmium, iridium, platinum, scandium, titanium, vanadium, chrome, manganese, copper, zinc, gold, silver or silicide thereof in a form of island, line, stripe, dot or film on or under an amorphous silicon film and using them as a starting point, by advancing its crystallization by annealing at a temperature lower than a normal crystallization temperature of an amorphous silicon. A transistor having low leak current and high mobility are obtained in the same time in a dynamic circuit having a thin film transistor by selectively forming a cover film on a semiconductor layer which is to become an active layer of the transistor and by thermally crystallizing it thereafter.
