摘要
Methods of analyzing the content of trace elements in silicon are considered. Silicon wafers in which the content of iron, copper and manganese were to be determined were investigated using a method based on the Hall effect, radiochemical methods and atomic absorption with electrothermal atomization. The results obtained are compared with the aim of determining the most accurate method of analysis.
