Abstract
Method for forming a polycrystalline silicon (ploy-Si) film of a semiconductor device includes forming the gate electrode on a substrate and depositing a dielectric layer on the substrate and the conductive layer. Then a first layer (microcrystalline silicon:.mu.c-Si) is formed on the dielectric layer and a second layer (hydrogenated amorphous silicon:a-Si:H) is deposited on the first layer. Noted that the polycrystalline silicon (poly-Si) can be fabricated by applying the laser annealing to the first layer and the second layer to transform them to poly-Si. Annealing the first layer and the second layer by laser, followed by fabricating the source and drain electrodes, thus the TFT with good electrical characteristics is fabricated.
