IEC 60749-18:2019

Semiconductor devices - Mechanical and climatic test methods - Part 18: Ionizing radiation (total dose)

IEC 60749-18:2019 provides a test procedure for defining requirements for testing packaged semiconductor integrated circuits and discrete semiconductor devices for ionizing radiation (total dose) effects from a cobalt-60 (60Co) gamma ray source. Other suitable radiation sources can be used. This document addresses only steady-state irradiations, and is not applicable to pulse type irradiations. It is intended for military- and aerospace-related applications. It is a destructive test. This edition includes the following significant technical changes with respect to the previous edition:
- updates to subclauses to better align the test method with MIL-STD 883J, method 1019, including the use of enhanced low dose rate sensitivity (ELDRS) testing;
- addition of a Bibliography, which includes ASTM standards relevant to this test method.

Dispositifs à semiconducteurs - Méthodes d'essais mécaniques et climatiques - Partie 18: Rayonnements ionisants (dose totale)

L’IEC 60749-18:2019 présente une procédure d’essai permettant de définir les exigences pour soumettre à essai des circuits intégrés à semiconducteurs sous boîtier et des dispositifs discrets à semiconducteurs, concernant les effets des rayonnements ionisants (dose totale) provenant d’une source de rayons gamma au cobalt-60 (60Co). D’autres sources de rayonnements appropriées peuvent être utilisées. Le présent document ne concerne que les irradiations continues et ne s’applique pas aux irradiations pulsées. Il est destiné aux applications des domaines militaire et aérospatial. Il s’agit d’un essai destructif. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
- mises à jour apportées aux paragraphes afin de mieux aligner la méthode d’essai avec la méthode 1019 du document MIL-STD 883J, comprenant l’utilisation de l’essai de sensibilité accrue au faible débit de dose (ELDRS);
- ajout d’une bibliographie, comprenant les normes ASTM correspondant à la présente méthode d’essai.

Part 18: Ionizing radiation (total dose)

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
This redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition. A vertical bar appears in the margin wherever a change
has been made. Additions are in green text, deletions are in strikethrough red text.

International Standard IEC 60749-18 has been prepared by IEC technical committee 47:
Semiconductor devices.
This second edition cancels and replaces the first edition published in 2002. This edition
constitutes a technical revision.
