Latest Patents: Xuejie Shi holds a patent titled "Metal-induced crystallization of amorphous silicon, polycrystalline silicon thin films produced thereby and thin film transistors produced therefrom." This patent describes a process where crystallization-inducing metal elements are introduced onto an amorphous silicon thin film. A first, low-temperature heat treatment induces nucleation of metal-induced crystallization (MIC), resulting in the formation of small polycrystalline silicon 'islands.' A metal-gettering layer is formed on the resulting partially crystallized thin film. A second, low-temperature heat treatment completes the MIC process while gettering metal elements from the partially crystallized thin film. This innovative process results in the desired polycrystalline silicon thin film.
