Norm ASTM F1527-00
1.1 This guide covers the application of Standard Reference Materials (SRMs ) for resistivity measurements on silicon wafers. Specifically, this guide covers the use of these SRMs for preparing resistivity reference wafers and for ensuring the quality of the instrumentation used for preparing them.
1.2 This guide has not been evaluated for application to electronic materials other than silicon.
1.3 The guide covers the selection of materials for resistivity reference wafers, procedures for preparing and calibrating resistivity reference wafers, and use of resistivity reference wafers in qualifying, calibrating, and controlling various types of resistivity instrumentation.
1.4 The guide provides criteria for selection of instruments for determining the resistivity of silicon resistivity reference materials, procedures for maintaining such instruments in statistical quality control, and training requirements for operators engaged in making and using resistivity reference wafers.
1.5 Appendixes are included that cover (1) suggested control charting procedures for organizations that do not already have such procedures in place, and (2) errors in resistivity determination that result from uncertainties in wafer diameter, wafer thickness, and probe-tip spacing.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
