摘要:
In an effort to determine the low-temperature limit for the growth of Si and Si(1-x)Ge(x) epitaxial layers in an atmospheric-pressure chemical vapor deposition (CVD) reactor, good quality material has been obtained at temperatures down to 600-degrees-C, using SiH2Cl2 and GeH4 in H-2 ambient. Si/Si(1-x)Ge(x)/Si heteroepitaxial structures are of good crystalline quality as well, showing abrupt interfaces. The Si-growth rate enhancement, caused by the addition of GeH4 to the gas flow at low temperatures, turns into growth-rate inhibition at higher temperatures. In this experiment oxygen and water partial pressures are several orders of magnitude higher than in ultrahigh vacuum CVD, without causing noticeable negative effects.
