ALPHA RADIATION MEASUREMENT IN ELECTRONIC MATERIALS

JESD221

Published: May 2011

This standard applies generally to gas proportional instruments and the use thereof in measuring materials with an alpha emissivity of less than 10 a·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.

TEST METHOD FOR ALPHA SOURCE ACCELERATED SOFT ERROR RATE

JESD89-2A

Published: Oct 2007

Status: Reaffirmed> January 2012

This test method is offered as standardized procedure to determine the alpha particle Soft Error Rate (SER) sensitivity of solid state volatile memory arrays and bistable logic elements (e.g. flipflops) by measuring the error rate while the device is irradiated by a characterized, solid alph source.
