ABSTRACT:
A silicon film is crystallized in a predetermined direction by selectively adding a metal element having a catalytic action for crystallizing an amorphous silicon and annealing. In manufacturing TFT using the crystallized silicon film, TFT provided such that the crystallization direction is roughly parallel to a current-flow between a source and a drain, and TFT provided such that the crystallization direction is roughly vertical to a current-flow between a source and a drain are manufactured. Therefore, TFT capable of conducting a high speed operation and TFT having a low leak current are formed on the same substrate.
