Ta del standarda IEC 62047 določa preskusno metodo na mestu uporabe za merjenje spojne trdnosti mikro spojnega mesta, ki je izdelano z mikromehansko tehnologijo proizvodnje MEMS na siliciju.
Ta dokument se uporablja za merjenje potezno-potisne in strižne trdnosti spojnih mest, ki so izdelana v procesu mikroelektronske in druge mikromehanske tehnologije.
Mikro sidro, pritrjeno na substrat skozi mikro spojno mesto, zagotavlja mehansko podporo premičnih funkcijskih komponent zaznavanja/aktiviranja v napravah MEMS. S spreminjanjem velikosti naprav je spojna moč zaradi napak, onesnaženja in toplotnega neujemanja na spojnem mestu vse manjša. Ta standard določa preskusno metodo na mestu uporabe za potezno-potisno in strižno trdnost na podlagi strukturirane tehnike.
Ta dokument ne zahteva uporabe zapletenih instrumentov (na primer mikroskopije s sondo za skeniranje in nanoindenterjev) in posebne priprave preskusnega primerka.
Ker je preskusno strukturo v tem standardu mogoče vključiti v izdelavo naprave kot standardni vzorec odkrivanja, je ta dokument lahko most, prek katerega oblikovalec iz proizvodnega obrata dobi kvantitativno referenco.

Overview

EN 62047-25:2016 (adoption of IEC 62047-25:2016, published by CLC/CENELEC) defines an in‑situ measurement method for assessing the bonding strength of micro bonding areas in silicon‑based MEMS fabrication technology. The standard targets the mechanical integrity of micro anchors and bonded interfaces produced by microelectronic and micromachining processes and specifies procedures for pull‑press (tension/compression) and shearing strength measurements that can be implemented as part of standard device fabrication.

Key topics and requirements

• Scope: Applies to silicon‑based MEMS bonding areas fabricated by microelectronic and other micromachining technologies for in‑situ testing.
• Testing structure design and fabrication: Requirements for embedding dedicated test patterns/structures into wafers so bond strength can be evaluated without separate specimen preparation (see Annex A/B for example dimensions and test structure guidance).
• Testing environment: Conditions and basic environment requirements for consistent, repeatable measurements.
• Testing methods:
  • Pull‑press testing (tensile/compressive) - method for imposing load, operation sequence and result processing (sections 5.2.x).
  • Shearing testing - procedure for lateral load application, operation sequence and result processing (sections 5.3.x).
• Result reporting: Procedures for processing measured data and deriving tensile, compressive and shear strength values for micro bonding areas.
• Practical instrumentation: Designed to avoid reliance on intricate instruments (e.g., scanning probe microscopy or nanoindenters) and instead use patterned test structures compatible with standard test equipment.

Applications and who should use it

• MEMS foundries and process engineers - for inline process control and statistical monitoring of bonding quality during fabrication.
• Device designers and packaging engineers - to obtain quantitative bond strength data to inform anchor design and material selection.
• Quality assurance and reliability labs - for production acceptance tests, failure analysis and thermal‑mismatch assessments.
• R&D teams - validating new bonding processes, surface treatments, or micromachining variants with standardized, repeatable tests.

Practical benefits include enabling on‑wafer, reproducible bond strength measurements, providing a bridge between foundry process control and designer requirements, and reducing the need for specialized nanoscale instruments.

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.

Part 25: Silicon based MEMS fabrication technology – Measurement
method of pull-press and shearing strength of micro bonding area

1 Scope
This part of IEC 62047 specifies the in-situ testing method to measure the bonding strength of
micro bonding area which is fabricated by micromachining technologies used in silicon-based
micro-electromechanical system (MEMS).
This document is applicable to the in-situ pull-press and shearing strength measurement of
the micro bonding area fabricated by microelectronic technology process and other
micromachining technology.
Micro anchor, fixed on the substrate through the micro bonding area, provides mechanical
support of the movable sensing/actuating functional components in MEMS devices. With the
devices scaling, the bonding strength degradation, induced by defects, contaminations and
thermal mismatch stress on bonding surface, becomes severer. This standard specifies an in-
situ testing method of the pull-press and shearing strength based on a patterned technique.
This document does not need intricate instruments (such as scanning probe microscopy and
nanoindenter) and to prepare the test specimen specially.
Since the testing structure in this standard can be implanted in device fabrication as a
standard detection pattern, this document can provide a bridge, by which the fabrication
foundry can give some quantitat
