Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard uses the translation method equivalent to ISO 12406..2010 "Surface chemistry analysis of secondary ion mass spectrometry in the depth of arsenic analysis of silicon method". And the normative reference in this standard international documents are consistent with the relationship between China's documents are as follows. GB/T 22461-2008 Surface chemistry analysis Glossary (ISO 18115..2001, IDT) This standard is proposed by the National Micro-Standardization Technical Committee (SAC/TC38). This standard is responsible for drafting units. China Electronics Technology Group Corporation forty-sixth Institute. The main drafters of this standard. Ma Nongong, Chen Xiao, He Youqin, Wang Dongxue.

Introduction

This standard is the use of secondary ion mass spectrometry (secondary-ionmassspectrometry, SIMS) on the quantitative analysis of arsenic in silicon And developed. For quantitative depth analysis, concentration and depth calibration are essential. The national standard GB/T 20176 specifies the boron concentration in silicon The method of determination. The International Standard ISO 17560 [1] specifies the boron depth analysis method for silicon. National standard GB/T 25186 provides A method for the determination of the relative sensitivity factor (RSF) of the ion implantation reference substance. National standards GB/T 22461 established in the surface chemistry Glossary of terms in the field of terminology and spectral terminology. The standard method for quantitative analysis of arsenic in silicon in this standard will refer to these national standards. This standard is suitable for the use of secondary ion mass spectrometry for single crystal silicon, polysilicon, amorphous silicon arsenic elements in depth analysis, and with stylus Surface profiler or optical interferometer depth calibration method. Surface chemistry analysis secondary ion mass spectrometry Depth analysis of arsenic in silicon

1 Scope

This standard specifies the method of depth analysis of arsenic in silicon with a sector magnetic field or a quadrupole secondary ion mass spectrometer, Stylus profiler or optical interferometer depth calibration method. This standard applies to arsenic atoms in the range of 1 × 1016 atoms/cm3 ~ 2.5 × 1021 atoms/cm3 monocrystalline silicon, polysilicon, amorphous silicon samples, pit depth of 50nm and above.
