step of retardation
step of retardation 双语例句
The degree of retardation of oxygen precipitation was different by n-type heavily dopants. On the condition of the same concentration of dopants and oxygen in heavily doped Cz-si, dopant of As had stronger retardation-3-than dopant of P.(3) The morphology of induced defects by oxygen precipitate in heavily doped Cz-si was affected by n-type dopants. Stacking faults were observed in heavily P-doped Cz-siliocn, but dislocation loops were observed in heavily As-doped Cz-si. Because of that the nucleation critical radius of oxygen precipitate in heavily doped Cz-si is affected by dopants, combined with free-electron effect and dopant-intrinsic point defect interaction, there are reverse influence on oxygen precipitation in heavily doped Cz-si between p-type and n-type dopants. Owing to the covalent radii effect of dopant, the degree of retardation of oxygen pricipitation and the morphology of induced defects by oxygen precipitates are not same among n-type heavily P-doped Cz-si.2. With different nucleation annealing, the behavior of oxygen precipitates and induced defcts in heavily As-doped Cz-si after two step Lo-Hi temperature annealing was investigated. It was found that (1) Heavily dopant of Sb only retarded the nucleation of oxygen precipitates and had no influence on the growth of oxygen precipitates, and stacking faults was observed. Heavily dopant of As retarded not only the nucleation but also the growth of oxygen precipitation, and dislocation loops was observed.(2) oxygen precipitation behavior in heavily doped Cz-si wafers wer
采用不同低温形核条件，对低高温两步退火重掺As、Sb硅片氧沉淀及其诱生缺陷行为深入研究，指出：重掺sb原子对氧沉淀的低温形核有抑制作用，而对氧沉淀的高温长大不产生影响，氧沉淀诱生缺陷形态与轻掺P硅片表现相同，均为层错；重掺As原子不仅对氧沉淀的低温形核有抑制作用，同时还影响氧沉淀的高温长大，使氧沉淀诱生缺陷形态不同于轻掺硅片，氧沉淀诱生缺陷为位错环；(2)低温形核条件对重掺硅片氧沉淀及其诱生缺陷行为有很大影响，慢速线性升温退火由于能使低温氧沉淀核心的形成与长大同时进行，相对于等温退火而言，显著地促进了后续高温氧沉淀形成，氧沉淀诱生缺陷密度增高。3，本文对RTP方法应用于重掺N型硅片氧的内吸杂作了研究，指出：(1) RTP方法可以成功地应用于重掺N型硅片氧的内吸杂：经高温RTP预处理并结合后续退火处理，重掺N型硅片表面形成有效的洁净区，体内形成氧沉淀及其诱生缺陷；(2)为了使重掺N型硅片体内形成合理密度的体缺陷富集区，硅片在RTP方法预处理后仍需结合低高温两步退火，低温氧沉淀形核预处理是必不可少的步骤。
