项目摘要

1. Seven kinds of silicon wafers with different oxygen concentration and with different production processes were irradiated by neutrons with different energy spectra, i.e., at pneumatic tube facility and thermal column facility of Kyoto University Research Reactor Institute, and at the fast neutron source of YAYOI (Nuclear Engineering Research Laboratory, University of Tokyo). The resistivities of the irradiated silicon wafers were measured by four probe method. The energy levels and their concentrations were measured at 90K to 350K by the semiconductor impurity measuring system. With these measurements, thermal neutron, which was taken as ineffective for the production of the lattice defects, was found effective. A lattice defect with unfamiliar energy level was observed.2. Oxygen ions and silicon ions were injected into silicon wafers by using tandem accelerator of Department of Engineering, Kyoto University. The concentration of the produced lattice defects were observed by the channeling method : low concentration defect with no irradiation dose dependence at the surface and high concentration defect with strong dependence on dose at the end of ion range. A model was developed which included the recombination, diffusion of point defects, production of defect clusters and amorphous and their accumulation. With model calculations, the defects at the surface were shown as point defects, and at the end of range as amorphous defects.
1. 用不同能谱的中子辐照7种不同氧浓度、不同生产工艺的硅片,分别在京都大学反应堆研究所的气动管设备、热柱设备和东京大学核工程研究实验室的快中子源辐照。用四探针法测量了辐照硅片的电阻率。用半导体杂质测量系统在90K ~ 350K温度下测量了能级和浓度。通过这些测量,发现热中子对晶格缺陷的产生是有效的,而热中子对晶格缺陷的产生是无效的。观察到一个不熟悉能级的晶格缺陷。利用日本京都大学工学系的双列加速器将氧离子和硅离子注入硅片。通过通道法观察所产生的晶格缺陷的浓度:表面低浓度缺陷与辐照剂量无关,离子范围末端高浓度缺陷与辐照剂量有很强的依赖性。建立了点状缺陷的复合、扩散、缺陷团簇和非晶态的产生及其积累的模型。通过模型计算,表面缺陷显示为点状缺陷,末端缺陷显示为非晶态缺陷。
