    Notes:
    Pattern dependence of the growth rate and Ge content in selective epitaxial Si1−xGex growth using reduced-pressure chemical vapor deposition has been examined for the SiH2Cl2-GeH4-H2 system. Contrary to selective epitaxial Si growth where pattern dependence diminishes at low growth temperatures, the growth rate of selectively grown Si1−xGex layers depends on the ratio of the exposed Si area to the oxide-covered area on a wafer, at temperatures as low as 600 °C. The Ge content in the layers also depends on the ratio, and the dependence is greater at higher temperatures. Adding HCl to the gas phase decreases the pattern dependence of both growth rate and Ge content. Although, in terms of the growth rate, an optimum HCl flow rate for pattern-insensitive growth exists, the Ge content in the layers is always higher for the wafer with a smaller exposed area. © 1995 American Institute of Physics.

    Notes:
    We have investigated the effects of boron doping on the electrical properties of glow-discharge amorphous silicon (a-Si:H) films prepared at a high-deposition rate (HDR), comparing these effects with those of lower rates. The HDR a-Si:H showed a higher doping efficiency, i.e., a larger portion of substitutionally doped boron than the other films by means of dark conductivity, activation energy measurements and quantitative analysis of boron. It also showed that the minimum B2H6 to SiH4 ratio which changes the film from intrinsic to p-type in photoconductivity is one order of magnitude smaller than that for dark conductivity.

    Notes:
    Hard hydrogenated amorphous carbon (a-C:H) films were coated on amorphous silicon photoreceptors by the plasma decomposition of acetylene (C2H2). This overlayer proved to be a much better protective layer for the adsorption of external species compared to an a-SiNx or a-Si1−xCx overcoating layer, and the image degradation induced by such adsorption was considerably reduced. The highly protective properties were attributed to the hydrophobic nature of C–Hn (n=1–3) and C–C bonds contained in the a-C:H film. The optical properties of the a-C:H films are also described.

    Notes:
    We have found a strong correlation between intrinsic stress and hydrogen bonding in glow-discharge amorphous silicon (a-Si:H) films. The stress of high-deposition-rate (HDR) films continuously changes from tensile to compressive with increasing rf power. In contrast, low-deposition-rate (LDR) films indicated compressive stress in all the rf power range which was varied. However, adding a small amount of Ar to SiH4 in the LDR film deposition changes its stress from compressive to tensile as in the HDR films. IR absorption spectroscopies showed that films with compressive stress always indicated a smaller ratio of absorptions at 2070 and 2000 cm−1 α(2070)/α(2000) than the value Rc(=0.9–1.2), whereas those with tensile stress showed a larger ratio. Consequently, zero or very weak stress is reached at the ratio approximately equal to Rc, regardless of varying deposition parameters. It is also shown that annealing alters the stress of all the HDR films to strong tensile, and that α(2070)/α(2000) decreases, differing from the correlation where the rf power and Ar mixing ratio are varied.

    Notes:
    The dependences of the Ge/Si ratio in epitaxial Si1−xGex layers grown using a SiH2Cl2–GeH4–H2 mixture by reduced-pressure chemical vapor deposition on the flow rate ratio of GeH4/SiH2Cl2 and on the total flow rate have been examined in the temperature range from 480 to 600 °C. As previously reported, the Ge/Si ratio does not increase linearly with the flow rate ratio; instead, the rate of increase decreases at high flow rate ratios. Additionally, it increases with increasing total flow rate when the ratio of GeH4/SiH2Cl2 is fixed. It is found that these flow rate dependences are well accounted for by assuming that the reaction order for SiH2Cl2 adsorption is twice as large as that for GeH4 adsorption. © 1996 American Institute of Physics.
