Semiconductor devices - Micro-electromechanical devices - Part 8: Strip bending test method for tensile property measurement of thin films
IEC 62047-8:2011 specifies the strip bending test method to measure tensile properties of thin films with high accuracy, repeatability, moderate effort of alignment and handling compared to the conventional tensile test. This testing method is valid for test pieces with a thickness between 50 nm and several mum, and with an aspect ratio (ratio of length to thickness) of more than 300. The hanging strip (or bridge) between two fixed supports are widely adopted in MEMS or micro-machines. It is much easier to fabricate these strips than the conventional tensile test pieces. The test procedures are so simple to be readily automated. This international standard can be utilized as a quality control test for MEMS production since its testing throughput is very high compared to the conventional tensile test.

La CEI 62047-8:2011 spécifie la méthode d'essai de flexion de bandes, afin de mesurer les propriétés de traction des couches minces avec une haute précision, répétabilité, un effort modéré d'alignement et de manipulation en comparaison de l'essai de traction conventionnel. La méthode d'essai est valable pour les éprouvettes d'essai dont l'épaisseur est comprise entre 50 nm et plusieurs mum, et dont le rapport, (soit le rapport de la longueur de l'éprouvette à son épaisseur) est supérieur 300. La bande suspendue (ou le pont) entre deux supports fixés est largement adoptée dans les MEMS ou dans les micromachines. Ces bandes sont bien plus faciles à fabriquer que les éprouvettes d'essai à la traction conventionnelles. Les procédures d'essai sont si simples qu'elles sont aisément automatisées. La présente norme internationale peut être utilisée en tant qu'essai de contrôle de la qualité pour la production des MEMS étant donné que son débit d'essai est très élevé comparé à l'essai de traction conventionnel.
Polprevodniški elementi - Mikroelektromehanski elementi - 8. del: Preskusna metoda z upogibanjem traku za merjenje nateznih lastnosti tankih plasti
Ta mednarodni standard opredeljuje preskusno metodo z upogibanjem traku za merjenje nateznih lastnosti tankih plasti z visoko natančnostjo, ponovljivostjo, zmernim naporom pri naravnavi in ravnanju v primerjavi s konvencionalnim nateznim preskusom. Ta metoda preskušanja velja za preskušance debeline med 50 nm in nekaj mm in z razmerjem dolžina/debelina več kot 300. Viseči trak (ali most) med dvema pritrjenima oporama se široko uporablja pri MEMS ali mikrostrojih. Mnogo lažje je proizvesti te trakove kot preskušance za konvencionalni natezni preskus. Postopki preskušanja so tako preprosti, da jih je mogoče hitro avtomatizirati. Ta mednarodni standard se lahko uporabi kot kontrolni preskus kakovosti za proizvodnjo MEMS, saj je njegova prepustnost količine na enoto časa zelo visoka v primerjavi s konvencionalnim nateznim preskusom.

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.
