Abstract(in English) | Microstructures of Si_<0.6>Ge_<0.4> films were investigated by using a transmission electron microscopy (TEM) in order to clarify the low temperature crystallization mechanism in the Ni-metal induced lateral crystallization (Ni-MILC) process. In the specimen annealed at 450 ℃, narrow needlelike Si_<0.6>Ge_<0.4> crystallites about 30 nm in width are formed and a hemispherical Ni (Si_<1-x>Ge_x) nodule was recognized at each crystallization front. At 550 ℃, on the other hand, dendritic crystals composed of many SiGe grains about 200 nm in diameter was observed in the MILC region. In addition, needlelike crystallites were also found to penetrate the center of the dendritic aggregates. These results suggest that the needlelike SiGe crystallites are formed first in association with the formation and migration of Ni (Si_<1-x>Ge_x) precipitate, and subsequently SiGe grains are crystallized on the needlelike crystallites by the spontaneous nucleation and growth. |
