Crystallized silicon
WebNov 1, 1999 · Very thin (25–50-nm-thick) amorphous silicon (a-Si) films were crystallized into polycrystalline silicon (polysilicon) films by the combination of low temperature solid phase crystallization (SPC) and subsequent excimer laser annealing (ELA). These films are, then, subjected to a standard low temperature process (<600 °C) of thin film transistor … WebJan 1, 1991 · During the crystallization process of micro amorphous silicon nitride powder, the chlorine impurities inhibit grain growth, resulting in a delay of the initiation of crystallization.
