Large grain silicon thin films produced by excimer laser annealing

总结: Polycrystalline silicon thin film transistors used in active matrix liquid crystal display devices are produced by melting and recrystallization of amorphous silicon. However, the boundaries between silicon crystal grains created during annealing reduce electron mobility, thereby increasing electrical resistance and reducing efficiency. This technology uses an excimer laser annealing method with multiple laser tubes to increase silicon crystal grain size. The larger grain sizes increase electron mobility, improve the performance of silicon thin film transistors, and enable the production of higher quality displays in electronic devices.
