摘要
本文借助于双晶x 射线衍射( D C D) 和椭园偏光谱( E S) 研究了注入能量为160ke V.不同剂量和不同退火温度(500 ~700 ℃) As + 注入 Si 的性质.用x 射线衍射的动力学理论和多层模型拟合了双晶衍射的摇摆曲线,得到了晶格应变随深度的分布.结果表明,注入剂量1 ×1016cm - 2 ,退火温度600 ℃形成了外延层.
The properties of As + implanted silicon with an energy 160 keV, different doses and annealing temperatures (500~700℃) were studied by means of x ray double crystal diffraction (DCD) and ellipometric spectra (ES). The rocking curves of DCD were simulated by multilayer model of dynamical theory, to obtain strain distributions as a function of depths. The 1×10 16 cm -2 annealed at 600℃ was found that a epitaxial layer was formed. The ES result proves above conclusion.The properties of As + implanted silicon with an energy 160 keV, different doses and annealing temperatures (500~700℃) were studied by means of x ray double crystal diffraction (DCD) and ellipometric spectra (ES).
