20、ional 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 electron

21、ic 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;

22、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 Standa

23、rdization (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 rep

24、resentation 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, I

25、EC 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 publ

26、ications. 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 are

27、as, 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 includ

35、r MEMS materials 1 Scope This part of IEC 62047 specifies micro-pillar compression test method to measure compressive properties of MEMS materials with high accuracy, repeatability, and moderate effort of specimen fabrication. The uniaxial compressive stress-strain relationship of a specimen is meas

36、ured, and the compressive modulus of elasticity and yield strength can be obtained. The test piece is a cylindrical pillar fabricated on a rigid (or highly stiff) substrate by micro-machining technologies, and its aspect ratio (ratio of pillar diameter to pillar height) should be more than 3. This s

37、tandard is applicable to metallic, ceramic, and polymeric materials. 2 Normative references The following referenced documents are indispensable for the application of this document.

To minimize the size effect of a test piece, the structure and size of the test piece s

42、hould be similar to those of the device components. There are many fabrication methods of the test piece depending on the applications. 4.2 Shape of test piece This standard specifies the compressive properties of a cylindrical micro-pillar. The micro-pillars are fabricated on a substrate using micr

43、o-machining process. The shape and the verticality of the pillars should be checked using electron or optical microscopy. The boundary condition on the bottom surface of the pillar is usually regarded as the fixed boundary, and these boundary conditions are different from those of bulk scale pillars

44、 where the top and bottom surfaces are usually lubricated and regarded as the frictionless boundary. Since it is also difficult to directly measure the compressive strain of the micro-pillar during the test, the strain is estimated from the displacement of the rigid punch using the Equation (2) of 5

45、.1. This leads to errors in strain, and consequently errors in elastic modulus and yield strength as described in Annex A. The accuracy of this method depends on the friction coefficient between the punch and the top surface, and the aspect ratio of the micro-pillar. The pillar with high aspect rati

46、o is desirable for reducing the errors in strain estimation unless the buckling occurs. The upper limit of aspect ratio is dependent on boundary conditions and material properties of the pillar. The maximum aspect ratio is suggested as 10 41. When there is no buckling after test for a pillar with an

47、 aspect ratio larger than 10, the test data should be considered as a valid one. The friction coefficient on the top surface can be reduced by applying a lubricating layer for bulk pillars (see 4), but it is very difficult to apply the lubricating layer to micro-pillars. The maximum variation in dia

48、meter of a cross-section of a pillar should be less than 1 % of the nominal diameter. When this is not the case, the actual cross-sectional area should be measured. 4.3 Measurement of dimensions To analyze the test results, the accurate measurement of the test piece dimensions is required since the

49、dimensions are used to extract mechanical properties of test materials. The diameter and the height of the pillar should be measured with high accuracy with less than 1 % error. Interferometric technique or FIB (Focused Ion Beam) sectioning can be utilized to measure the height accurately. The test piece can have a changing cross-section in the longitudinal direction and the diameter or the top surface can be different from that of the bottom surface. This dimens
