ABSTRACTMicrocrystalline silicon with high crystallinity was fabricated on a glass substrate at a rather low temperature (320 C) by alternately repeating the deposition of Si thin layer 10 nm thick from fluorinated precursors and the treatment with atomic hydrogen. Hydrogen content was reduced to 0.5 at% or less. According to the in situ ellipsometric observation, the sticking of precursors followed the reactions for the construction of the ordered structure with the aid of atomic hydrogen. In addition, the defects were passivated efficiently with the treatment down to 4×1016 spins/cm3. A marked improvement was simultaneously verified in the efficiency of the substitutional P-doping in the films fabricated by this layer-by-layer technique.

AbstractGrazing incidence x-ray diffraction has been employed to perform the depth-profile analysis on SrBi2Ta2O9 (SBT) thin films with different preferential orientations. For the polycrystalline SBT thin film, the change in structural orientation occurs only within the 15-nm-thick top layer, which is associated with the formation of the (200)-predominant SBT thin film prepared by the layer-by-layer annealing process. The inhomogeneity of structural orientation is more significant in the full film thickness for the (200)- predominant SBT thin film. (0010) peak can only be observed for the grazing angle larger than 0.6°. A layer with the highest ratio of I(200)/I(115) is found in the top surface layer (i.e., the latest layer during deposition) of the (200)-predominant SBT thin film.

AbstractFor application as nucleation layer in thin film devices, microcrystalline silicon was deposited with the layer-by-layer technique using plasma excitation frequencies between 27 and 95 MHz, various hydrogen treatment times and various film thicknesses per layer. An optimum phase transformation is found at an intermediate plasma excitation frequency, i.e. at this frequency the shortest hydrogen annealing time is necessary for an effective amorphous-to-crystalline phase transformation.
