Latest Patents

Li-Jing Cheng holds a patent for a "Recrystallization method of polysilicon film in thin film transistor." This invention proposes a crystallization method for the poly-Si thin film in a thin film transistor. The process involves providing a substrate with an insulator layer, followed by the formation of an amorphous silicon layer or a micro-crystalline silicon layer of varying thickness. The thinner region is designated as the channel region, while the thicker region serves as the source/drain regions. An excimer laser is then utilized for crystallization, where the amorphous silicon layer of thinner is completely melted, and the thicker layer is partially melted. This method allows for the growth of a poly-Si layer with good homogeneity and large grains, enhancing the overall performance of the thin film transistor.
