Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 1550-1997 "Test method for conductivity type of extrinsic semiconductor materials", compared with GB/T 1550-1997 The main technical changes are as follows. --- The scope of application was changed to "This standard applies to the testing of conductivity types of silicon and germanium non-intrinsic semiconductor materials, and other extrinsic semiconductors. Materials can be tested with reference to this standard" (see Chapter 1, Chapter 1 of the.1997 edition); --- Added terms and definitions (see Chapter 3); --- Change the original standard 1.2~1.9 to "4.1 General" (see 4.1,.1997 version 1.2~1.9); --- Revised the scope of application of Method A, Method D1, Method D2 (see 4.1.2, 4.1.5, 4.1.6,.1997, 1.3, 1.6, 1.7); --- Added method E (surface photovoltage method) to test the conductivity type (see 4.1.7, 4.5, 5.5, 7.6, 9.5); --- Added "If you use 9.1 ~ 9.5 test steps to obtain stable readings and good sensitivity, then the sample table No stain or oxide layer on the surface. If the reading is unstable or the sensitivity is poor, it indicates that the surface of the sample has been stained or has an oxide layer. The surface of the sample was treated by the method of 8.2. " (see 9.6); --- Added analysis of test results (see Chapter 10). This standard is supported by the National Semiconductor Equipment and Materials Standardization Technical Committee (SAC/TC203) and National Semiconductor Equipment and Materials Standards. The Technical Subcommittee Materials Branch (SAC/TC203/SC2) jointly proposed and managed. This standard was drafted.

1 Scope

This standard specifies the test method for the conductivity type of extrinsic semiconductor materials. This standard is applicable to the testing of conductivity types of silicon and germanium non-intrinsic semiconductor materials. Other extrinsic semiconductor materials may be tested with reference to this standard. test. This standard method can ensure reliable results for uniform materials of the same conductivity type; for materials with non-uniform conductivity types, Different conductive type regions are measured on the surface. This standard does not apply to the testing of conductive types of layered structural materials such as epitaxial wafers.
