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 TPT using the crystallized silicon film, TFT provided such that the crystallization direction is roughly parallel...http://www.google.com.au/patents/US6482686?utm_source=gb-gplus-sharePatent US6482686 - Method for manufacturing a semiconductor device
