Alpha Radiation Measurement in Electronic Materials
Organization:
JEDEC - Solid State Technology Association
Year: 2011
Abstract: This standard applies generally to gas proportional instruments and the use thereof in measuring materials with an alpha emissivity of less than 10 ·khr-1·cm-2. The primary focus will be on materials used in semiconductor fabrication.
The purpose of this document is to specify the recommended method for measuring alpha emissivity in materials utilized in the manufacturing of semiconductors. The method specifically applies to gas proportional instruments and designates recommended instrument settings. In addition, the method discusses operation of ionization counters. The document also recommends methods for determining sample size and for evaluating instrument background accurately. Treatment of data is also outlined, including identification and elimination of systematic errors. The calculation of results and detection limits is detailed with examples in the annexes. A standard format for reporting results is specified.
