Semiconductor devices - Micro-electromechanical devices - Part 17: Bulge test method for measuring mechanical properties of thin films
IEC 62047-17:2015 specifies the method for performing bulge tests on the free-standing film that is bulged within a window. The specimen is fabricated with micro/nano structural film materials, including metal, ceramic and polymer films, for MEMS, micromachines and others. The thickness of the film is in the range of 0,1 μ to 10 μ, and the width of the rectangular and square membrane window and the diameter of the circular membrane range from 0,5 mm to 4 mm. The tests are carried out at ambient temperature, by applying a uniformly-distributed pressure to the testing film specimen with bulging window. Elastic modulus and residual stress for the film materials can be determined with this method.

L'IEC 62047-17:2015 spécifie la méthode permettant d'effectuer des essais de renflement sur une couche autonome bombée dans une fenêtre. Le spécimen est fabriqué avec des matériaux de couche de structure micrométrique ou nanométrique, y compris les couches en métal, céramique et polymère, pour des MEMS, des micromachines et autres. L'épaisseur du film est comprise entre 0,1 μ et 10 μ et la largeur de la fenêtre à membrane rectangulaire et carrée ainsi que le diamètre de la membrane circulaire sont compris entre 0,5 mm et 4 mm. Les essais sont effectués à température ambiante par l'application d'une pression uniformément répartie sur le spécimen de couche d'essai avec fenêtre bombée. Le module d'élasticité et la contrainte résiduelle des matériaux de la couche peuvent être déterminés avec cette méthode.
Polprevodniški elementi - Mikroelektromehanski elementi - 17. del: Izboklinska preskusna metoda za merjenje mehanskih lastnosti tankih plasti
Ta del standarda IEC 62047 določa metodo za izvajanje izboklinskih preskusov na samostojnem filmu, ki je izbočen v oknu. Primerek je izdelan z makro/nano strukturnimi filmskimi materiali, vključno s kovinskimi, keramičnimi in polimernimi filmi, za MEMS, mikrostroje in drugo. Debelina filma je med 0,1 μm in 10 μm, širina pravokotnega in kvadratnega membranskega okna in premer krožne membrane pa je med 0,5 mm in 4 mm. Preskusi se izvajajo pri okoljski temperaturi tako, da se na preskusni primerek filma z izbočenim oknom nanaša enakomerno razporejen pritisk. S to metodo se lahko določa elastični modul in preostalo mehansko napetost filmskih materialov.

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 reasonabl
