Abstract:
A buffer layer for promoting electron mobility. The buffer layer comprises amorphous silicon layer (a-Si) and an oxide-containing layer. The a-Si has high enough density that the particles in the substrate are prevented by the a-Si buffer layer from diffusing into the active layer. As well, the buffer, having thermal conductivity, provides a good path for thermal diffusion during the amorphous active layer's recrystallization by excimer laser annealing (ELA). Thus, the uniformity of the grain size of the crystallized silicon is improved, and electron mobility of the TFT is enhanced.

An amorphous silicon thin film is formed on a substrate first. Then the thin film is irradiated by a laser plus having an irradiation interval along a first direction to re-crystallize the thin film into a polysilicon thin film. A light source is thereafter focused into a micro spot having a diameter smaller than the irradiation interval, and the polysilicon thin film is irradiated by the micro spot moving along the first direction and having a relative moving distance to obtain a spectrum.
