Introduction

Neutron activation analysis (NAA) is capable of a variety of materials of various elements of high sensitivity quantitative and qualitative analysis. special Notably in the semiconductor industry, it is specified raw materials (for growing semiconductor grade monocrystalline silicon wafers and for analysis and evaluation of high-purity polysilicon Material) trace element contamination. PV industry, the growth of the silicon raw material demand led to more large-scale polysilicon production and purification of various silicon atoms Research and development of alternative materials. Produced by these methods of silicon material in the current literature generally referred to as solar grade silicon, and having a plurality Shapes, such as a lump, powder and granular. With the expansion of polysilicon and solar grade silicon production scale, quality control should also be strengthened, and instrumental neutron activation analysis (INAA) is One alternative method. The method of instrumental neutron activation analysis is a direct implementation of the irradiated samples analyzed, compared with the traditional radiochemistry Neutron activation analysis (RNAA) To irradiated sample chemical separation to remove interfering substances to be tested or concentrated radioactive isotopes Su. Currently, some laboratories using different neutron source, irradiation conditions, electronic equipment and sample preparation methods, to achieve the instrumental neutron activation points Analysis, and used in various forms, types of silicon samples. Instrumental neutron activation analysis of silicon standardized analytical methods will eliminate between Difference, so as to establish a common reference method of analysis. Instrumental neutron activation analysis of silicon test methods

1 Scope

1.1 standard specifies instrumental neutron activation analysis of silicon materials testing methods. Instrumental neutron 1.2 This standard applies to chemical vapor deposition method or a method for purifying metallurgical silicon produced by activation analysis. Analysis of samples can be Be monocrystalline, polycrystalline, and polycrystalline form may be a powder, a granule, or bulk silicon. 1.3 This standard applies to macroscopic material composition analysis. As an additional test method according to the sample preparation, and in sample extraction, transport And preparation process to avoid surface contamination, but also realize the sample surface or near-surface area analysis. 1.4 Test method applies only to Appendix A thermal neutron or epithermal neutron activation analysis of trace elements listed. 1.5 test method does not apply to the amorphous silicon thin-film polycrystalline silicon thin film analysis, or microcrystalline silicon thin film. For by artificially high doping concentration Laid Silicon sample special elements do not belong to the scope of this test method, but doping checked for safety, detection limits and the minimum waiting time tw0 After impact, the test method may also be applicable. 1.6 This test method is used to analyze a wide range of trace elements (see Appendix A). Generally, the irradiation time of the sample should be higher than 31Si decay lifetime Long, and the like should be generated after irradiation 31Si fully decay analysis can be implemented.
