AbstractIn this paper the reaction kinetics of Remote Plasma-enhanced Chemical Vapor Deposition (RPCVD) are investigated. Growth rate characterization has been performed for substrate temperatures of 220 – 400°C, r-f powers from 4 – 8 W, and silane flow rates of 10 – 30 sccm. Growth rate has been found to increase exponentially with r-f power, which is, as yet, unexplained. An approximate square root dependence of growth rate on silane partial pressure agrees with the theory of Claasen et. Al for Chemical Vapor Deposition (CVD) of silicon from silane with an inert carrier gas. From an Arrhenius plot of the temperature dependence of growth rate, we note a change of slope at ∼300°C which we have attributed to the behavior of hydrogen at the silicon surface.

ABSTRACTWe have deposited thin Ge films on GaAs(111) crystals over a temperature range of 250-400° C by Remote Plasma Enhanced Chemical Vapor Deposition (RPECVD). Rutherford Backscattering (RBS)/channelinf analysis of these heteroepitaxial films were carried out using 2.07 MeV He ions channeled along the <111> axis. RBS/channeling analysis showed that the best Ce films were grown at a substrate temperature of 300° C. The minimum yield for <111> channeling on films deposited at 300° C was 0.08, slightly greater than that of the GaAs crystal. Films grown at temperatures below 300° C showed poor epitaxy. No channeling was observed for the film grown at 250° C. Films grown at substrate temperatures above 350° C showed high dechanneling near the interface and poor epitaxy indicating films are highly defective. The RBS/channeling results are correlated with microstructural characterization using transmission electron microscopy of these films.

ABSTRACTChemical vapor deposition (CVD) of copper using both a novel Cu(II) β-diketonate source and hydrogen reduction process was studied to fill contact vias with the smallest diameter in the 32nm and more advanced generation chip. Pure Cu films were grown under the condition with the product of hydrogen partial pressure and H2/Cu source molar ratio being over 1,000,000. We succeeded in filling the 40-nm-diameter contact vias by optimizing the growth condition of the Cu-CVD in both substrate temperatures and reaction pressures.

Diffraction Patterns

Heteroepitaxial growth of Ge on Si(100) has been accomplished using remote plasma enhanced chemical vapor deposition at 300*#x00B0;C. Reconstructed surfaces with diffraction patterns showing non-uniform intensity variations along the lengths of the integral order streaks are observed during the first 100 Å of deposit. This observation of an atomically rough surface during the initial stages of growth is an indication of three-dimensional growth. As the epitaxial growth proceeds, the diffraction patterns become uniform with extensive streaking on both the integral and fractional order streaks. Subsequent growth, therefore, takes place in a layer-by-layer, two-dimensional mode. X-ray photoelectron spectroscopy of the early nucleation stages, less than 80 Å, show that there is uniform coverage with no evidence of island formation.
