Semiconductor devices - Mechanical and climatic test methods - Part 26: Electrostatic discharge (ESD) sensitivity testing - Human body model (HBM) (IEC 60749-26:2018)

This part of IEC 60749 establishes the procedure for testing, evaluating, and classifying
components and microcircuits according to their susceptibility (sensitivity) to damage or
degradation by exposure to a defined human body model (HBM) electrostatic discharge (ESD).
The purpose of this document is to establish a test method that will replicate HBM failures and
provide reliable, repeatable HBM ESD test results from tester to tester, regardless of
component type. Repeatable data will allow accurate classifications and comparisons of HBM
ESD sensitivity levels.
ESD testing of semiconductor devices is selected from this test method, the machine model
(MM) test method (see IEC 60749-27) or other ESD test methods in the IEC 60749 series.
Unless otherwise specified, this test method is the one selected.

Dispositifs à semiconducteurs - Méthodes d'essais mécaniques et climatiques - Partie 26: Essai de sensibilité aux décharges électrostatiques (DES) - Modèle du corps humain (HBM) (IEC 60749-26:2018)

L'IEC 60749-26:2018 établit une procédure pour les essais, l'évaluation et la classification des composants et des microcircuits en fonction de leur susceptibilité (sensibilité) aux dommages ou de leur dégradation à la suite de leur exposition à des décharges électrostatiques (DES) sur un modèle de corps humain (HBM) défini.
Le but du présent document est de déterminer une méthode d'essai permettant de reproduire les défaillances du HBM et de fournir des résultats d'essais de DES de HBM fiables et reproductibles d'un appareil d'essai à un autre, sans tenir compte du type de composant. Des données reproductibles autoriseront des classifications et des comparaisons précises des niveaux de sensibilité de DES de HBM.
Les essais de DES des dispositifs à semiconducteurs sont choisis entre la présente méthode d'essai, celle du modèle de machine (MM) (voir IEC 60749-27) ou toute autre méthode d'essai de la série IEC 60749. Sauf indication contraire, la présente méthode d'essai est celle qui prévaut.
Cette quatrième édition annule et remplace la troisième édition parue en 2013. Cette édition constitue une révision technique. La présente norme se base sur l'ANSI/ESDA/JEDEC JS-001-2014. Elle est utilisée avec l'autorisation des détenteurs des droits d'auteur, ESD Association et JEDEC Solid state Technology Association.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a)   un nouveau paragraphe sur la contrainte de HBM avec un simulateur à faibles parasites est ajouté, ainsi qu'un essai visant à déterminer si un simulateur de HBM est un simulateur à faibles parasites;
b)   un nouvel article est ajouté pour les broches clonées n'assurant pas l'alimentation et une nouvelle annexe est ajoutée pour les essais des broches clonées n'assurant pas l'alimentation.

Polprevodniški elementi - Metode za mehansko in klimatsko preskušanje - 26. del: Preskušanje občutljivosti na elektrostatično razelektritev (ESD) - Model človeškega telesa (HBM) (IEC 60749-26:2018)

Ta del standarda IEC 60749 določa standardni postopek za preskušanje, ocenjevanje in razvrščanje sestavnih delov in mikrovezij glede na občutljivost na poškodbe in degradacijo, ki so posledica izpostavljenosti določenim elektrostatičnim izpraznitvam (ESD) modela človeškega telesa (HBM).
Namen tega dokumenta je določiti preskusno metodo, ki bo ponovila napake modela človeškega telesa ter zagotovila zanesljive in ponovljive preskusne rezultate elektrostatičnih izpraznitev modela človeškega telesa pri vseh preskuševalcih ne glede na vrsto sestavnega dela. Ponovljivi podatki bodo omogočili natančne opredelitve in primerjave ravni občutljivosti na elektrostatične izpraznitve (ESD) modela človeškega telesa (HBM).
Preskus elektrostatične izpraznitve elementov se izbere iz te preskusne metode, preskusne metode modela stroja (MM; glej standard IEC 60749-27) ali drugih testnih metod iz serije standardov IEC 60749.
Če ni navedeno drugače, je treba izbrati to preskusno metodo.

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 60749-26 has been prepared by IEC technical committee 47:
Semiconductor devices in collaboration with technical committee 101: Electrostatics.
This fourth edition cancels and replaces the third edition published in 2013. This edition
constitutes a technical revision. This standard is based upon ANSI/ESDA/JEDEC JS-001-
2014. It is used with permission of the copyright holders, ESD Association and JEDEC Solid
state Technology Association.
This edition includes the following significant technical changes with respect to the previous
edition:
a) a new subclause relating to HBM stressing with a low parasitic simulator is added,
together with a test to determine if an HBM simulator is a low parasitic simulator;

---------------------- Page: 9 ----------------------

Part 26: Electrostatic discharge (ESD) sensitivity testing –
Human body model (HBM)



1 Scope
This part of IEC 60749 establishes the procedure for testing, evaluating, and classifying
components and microcircuits according to their susceptibility (sensitivity) to damage or
degradation by exposure to a defined human body model (HBM) electrostatic discharge (ESD).
The purpose of this document is to establish a test method that will replicate HBM failures and
provide reliable, repeatable HBM ESD test results from tester to tester, regardless of
component type. Repeatable data will allow accurate classifications and comparisons of HBM
ESD sensitivity levels.
ESD testing of semiconductor devices is selected from this test method, the machine model
(MM) test method (see IEC 60749-27) or other ESD test methods in the IEC 60749 series.
Unless otherwise specified, this test method is the one selected.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their
content constitutes requirements of this document. For dated references, only the edition
cited applies. For undated references, the latest edition of the referenced document (including
any amendments) applies.
There are no normative references in this document.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following
addresses:
