Faced with these problems, in particular, bonding problems, the microelectronics industry is constantly looking for techniques to characterize the bonding quality of wafer assemblies of electronic chips. We propose here, within the framework of the ANR DACLOS project, a non-destructive inspection method based on an original approach called acoustic field correlation to image this type of defects.<\/strong><br \/>\nObjectives :\nThe originality of the DACLOS project is to study the propagation of high frequency diffuse Rayleigh wave patterns in inhomogeneous LOS and their interaction with possible defects. The physical principle is based on proper processing of random high frequency elastic wave fields.<br \/>\nThis \u2018\u2019jump\u201d in frequency from (10-30 kHz) to approximately (10-30 MHz) for the DWC technique presents a double challenge: 1) creating an artificial high frequency diffuse noise and, 2) elaborating new mathematical algorithms for 2D LOS NDT&amp;E from Rayleigh waves. Recently, it is shown that the Rayleigh dispersion is still exploitable when the layer thickness is 100 times smaller than the wavelength. Consequently, the proposed method will allow performing 2D LOS NDT&amp;E with sparse measurement sources for LOS thickness smaller than the wavelength of the instrument operation.<\/p>\n<div class=\"\"><strong>The DACLOS team expect the following advantages:\u00a0\u00a0<\/strong><\/div>\n<div><\/div>\n<ul>\n<li>The proposed method will allow performing 2D LOS NDT&amp;E for LOS thickness smaller than the wavelength of the instrument operation;<\/li>\n<li>Implementing of DWC for LOS evaluation based on SAW-IDTs allows full 2D characterization with low number of IDTs sources.<\/li>\n<li>Due to the use of contact IDTs, there is no limitation on layer\u2019s material type. For example, this concerns transparent or fragile layers often causing difficulties when using other measurement methods such as \u201claser-ultrasound\u201d<\/li>\n<li>Using a laser vibrometer for detecting diffuse waves permits to obtain a high density of information. Therefore, several signal processing based on matrix imaging algorithms can be applied and consequently retrieve significant information about the state of health of the LOS samples.<\/li>\n<\/ul>\n<p style=\"font-weight: 400;\"><strong><span style=\"color: #800000;\">CONTACT :<\/span><\/strong><\/p>\n<p><strong>Dr. Lynda CHEHAMI<\/strong><br \/>\nIEMN site de Valenciennes, Groupe TPIA<br \/>\nUniversit\u00e9 Polytechnique des Hauts de France<br \/>\nF-59313 Valenciennes cedex 9<br \/>\nTel\u00a0: +33(0)3 27 51 11 87<br \/>\n<a href=\"mailto:Lynda.chehami@uphf.fr\"><span style=\"font-weight: 400;\">Lynda.chehami@uphf.fr<\/span><\/a><\/p>\n<\/div><\/section>\n<div class='flex_column_table av-237o9w1-e31f98e4cf06d668c03c0d3978576c28 sc-av_one_half av-equal-height-column-flextable'>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-237o9w1-e31f98e4cf06d668c03c0d3978576c28\">\n@keyframes av_boxShadowEffect_av-237o9w1-e31f98e4cf06d668c03c0d3978576c28-column {\n0%   { box-shadow:  0 0 0 0 #d3d3d3; opacity: 1; }\n100% { box-shadow:  0 0 10px 0 #d3d3d3; opacity: 1; }\n}\n.flex_column.av-237o9w1-e31f98e4cf06d668c03c0d3978576c28{\nbox-shadow: 0 0 10px 0 #d3d3d3;\nborder-width:2px;\nborder-color:#cccccc;\nborder-style:solid;\nborder-radius:10px 10px 10px 10px;\npadding:20px 20px 20px 20px;\n}\n<\/style>\n<div  class='flex_column av-237o9w1-e31f98e4cf06d668c03c0d3978576c28 av_one_half  avia-builder-el-8  el_after_av_textblock  el_before_av_one_full  first flex_column_table_cell av-equal-height-column av-align-bottom shadow-not-animated  column-top-margin'     ><section  class='av_textblock_section av-l48gdxv4-2ae09003fd94017ae2e0fee6578cc2d3'   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><h4><a href=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2020\/09\/logo_iemn_def.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-42329\" src=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2020\/09\/logo_iemn_def-300x110.jpg\" alt=\"\" width=\"300\" height=\"110\" srcset=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2020\/09\/logo_iemn_def-300x110.jpg 300w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2020\/09\/logo_iemn_def.jpg 340w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/h4>\n<h4><strong>Institut d\u2019Electronique, de Micro\u00e9lectronique et de Nanotechnologie, IEMN<\/strong><\/h4>\n<h4><em>Coordinator: Dr. Lynda Chehami <\/em><\/h4>\n<h4><em>Membres du projet : Marc Duquennoy, Emmanuel Moulin, et Nikolay Smagin<\/em><\/h4>\n<\/div><\/section><\/div><\/div><!--close column table wrapper.
