  • Patent number: 7629209
    Abstract: A method for fabricating polysilicon film is disclosed. First, a first substrate is provided, wherein a plurality of sunken patterns has been formed on the front surface of the first substrate. Then, a second substrate is provided and an amorphous polysilicon film is formed on the second substrate. Next, the amorphous polysilicon film formed on the second substrate is in contact with the front surface of the first substrate. The amorphous polysilicon film is transferred into a polysilicon film by performing an annealing process. Then, the first substrate and the second substrate are separated from each other. This method reduces the cost and the time for fabricating polysilicon film.

  • Publication number: 20080116461
    Abstract: A manufacturing method of a semiconductor device, includes the following steps: providing a substrate with an insulated surface; forming an amorphous silicon layer on the insulated surface; imposing a catalytic metal element on the amorphous silicon layer; heating and catalyzing the amorphous silicon layer to form a poly-silicon layer; forming a diffusion layer and a gettering material layer on the poly-silicon layer in order; proceeding an annealing process on the gettering material layer and the poly-silicon layer to move the residual metal catalyst element from the poly-silicon layer toward the gettering material layer due to the concentration gradient; and removing the diffusion layer and the gettering material layer.

  • Patent number: 6475835
    Abstract: A method for forming a thin film transistor (TFT) is disclosed. The invention uses metal electroless plating or chemical displacement processes to form metal clusters adjacent the sidewall of amorphous silicon active region pattern so as to crystallize the amorphous silicon amid the subsequently performed metal induced lateral crystallization (MILC) process. The amorphous silicon is crystallized to form polysilicon having parallel grains. Since the amorphous silicon will crystallize with a specific angle which is measured between the grain orientation and the side wall of the amorphous silicon, a tilt channel connecting the source and drain region of the TFT is utilized to upgrade the electron mobility across the tilt channel, wherein the grain orientation of polysilicon in the tilt channel perpendicular to a gate electrode which is subsequently formed above the tilt channel.
