MeV 4He离子的背散射已被用于分析沉积在单晶GaAs衬底上的SiO2和Si3N4电介质层中的Ga和As含量。在750 ° C和800°C等温退火后,观察到杂质浓度和分布的变化。Ga向外扩散的证据是清楚的。
Backscattering of MeV 4He ions has been used to analyze the Ga and As content in SiO2 and Si3N4 dielectric layers deposited on single‐crystal GaAs substrates. Changes in impurity concentrations and distributions are seen after isothermal annealing at both 750 and 800°C. Evidence for Ga outdiffusion is clear.
