Semiconductor devices - Mechanical and climatic test methods - Part 29: Latch-up test
IEC 60749-29:2011 covers the I-test and the overvoltage latch-up testing of integrated circuits. The purpose of this test is toestablish a method for determining integrated circuit (IC) latch-up characteristics and to define latch-up failure criteria. Latch-up characteristics are used in determining product reliability and minimizing 'no trouble found' (NTF) and 'electrical overstress' (EOS) failures due to latch-up. This second edition cancels and replaces the first edition published in 2003 and constitutes a technical revision. The significant changes with respect to the previous edition include: - a number of minor technical changes; - the addition of two new annexes covering the testing of special pins and temperature calculations.

La CEI 60749-29:2011 couvre l'essai I et l'essai de verrouillage de surtension des circuits intégrés. L'objet de cet essai est d'établir une méthode pour déterminer les caractéristiques de verrouillage des circuits intégrés (CI) et pour définir les critères de défaillance de verrouillage. Les caractéristiques de verrouillage sont utilisées pour la détermination de la fiabilité de produit et la minimisation des défaillances en rapport avec 'l'absence d'observation de problèmes' (NTF, No Trouble Found) et la 'contrainte électrique excessive' (EOS, Electrical Overstress) dues au verrouillage. Cette deuxième édition annule et remplace la première édition publiée en 2003 et constitue une révision technique. Les modifications importantes apportées par rapport à l'édition antérieure concernent: - un certain nombre de modifications techniques mineures; - l'addition de deux nouvelles annexes traitant de l'essai des broches spéciales et des calculs de température.
Polprevodniški elementi - Mehanske in klimatske preskusne metode - 29. del: Preskus zapore
Ta del IEC 60749 zajema preskus I in prenapetostni preskus zapore integriranih vezij Ta preskus je klasificiran kot porušitveni. Namen tega preskusa je vzpostaviti metodo za določanje zapornih značilnosti integriranega vezja (IC) in opredeliti merila za neuspešnost zapore. Zaporne značilnosti se uporabljajo pri ugotavljanju zanesljivosti proizvoda in zmanjševanju napak zaradi zapore »Ne najdem težave« (NTF) in »Električna prenapetost« (EOS). Ta preskusna metoda se uporablja predvsem za elemente CMOS. Uporabnost za druge tehnologije je treba ugotoviti. Klasifikacija zapore kot funkcije temperature je opredeljena v 3.1, merila za stopnjo neuspešnosti pa v 3.2.

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.
International Standard IEC 60749-29 has been prepared by IEC technical committee 47:
Semiconductor devices.
This second edition cancels and replaces the first edition published in 2003 and constitutes a
technical revision. The significant changes with respect to the previous edition include:
– a number of minor technical changes;
– the addition of two new annexes covering the testing of special pins and temperature
calculations.

voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 60749 series, under the general title Semiconductor devices –
Mechanical and climatic test methods, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
