Perhaps technologies delivering automation in factories and other production sites? That may be what comes to mind, but advances in organic electronics are now driving the rapid development of biological sensors that measure physiological signals when in contact with the skin, organs, and other parts of the body. https://www.leica-microsystems.com//science-lab/coming-to-grips-with-biological-information-through-flexible-organic-electronics-developing-bendable-and-stretchable-biosensors-and-device/ Wed, 28 Jun 2017 10:14:00 +0000 Kuniko Yagura, PhD James DeRose https://www.leica-microsystems.com/18225 EM Sample Preparation In-Containing Compound Semiconductors - Sample Preparation for TEM Application Note for Leica EM RES102 - Previous studies showed that surface accumulation of In occurs when InP was milled in a conventional way with Ar ions. The consequence is In islands on the sample surface. This leads to low quality of TEM samples. To remove these islands, reactive ion milling with iodine ions (RIBE / CAIBE) can be used. This method has the disadvantage of polluting the ion guns and the vacuum system of the ion milling device and leads to chemical reactions with the sample material. To avoid these problems we prepared these samples very gently with low energy Ar ions. https://www.leica-microsystems.com//science-lab/in-containing-compound-semiconductors-sample-preparation-for-tem/ Mon, 12 Dec 2016 10:13:00 +0000 PhD Wolfgang Grünewald https://www.leica-microsystems.com/18999 Digital Microscopy Quality Assurance How Digital Microscopy can Contribute to Efficient Workflows for Microelectronics and Electronics This report explains how users can benefit from the digital microscope portfolio of Leica Microsystems to attain cost-effectiveness over entire workflows in research and development (R&D), product innovation, process engineering, production, quality control and assurance (QC/QA), and failure analysis (FA). https://www.leica-microsystems.com//science-lab/how-digital-microscopy-can-contribute-to-efficient-workflows-for-microelectronics-and-electronics/ Wed, 30 Nov 2016 12:36:00 +0000 PhD James DeRose, Oscar Rodriguez https://www.leica-microsystems.com/18255 EM Sample Preparation "Shallow Trench Isolation" Structures - Sample Preparation for TEM Application Note for Leica EM RES102 - The cross-sectional preparation of structured semiconductor materials requires a very thorough mechanical pre-preparation. In doing this, it must be ensured that the structure of interest should be located as close to the centre of the sample as possible. As the sample will be ion milled from both sides, a specific preparation of the structure is necessary in most cases, which means that you must thin these structures from both sides. https://www.leica-microsystems.com//science-lab/shallow-trench-isolation-structures-sample-preparation-for-tem/ Fri, 18 Nov 2016 16:50:00 +0000 PhD Wolfgang Grünewald https://www.leica-microsystems.com/18213 EM Sample Preparation Cross-Sectional Preparation of Structured Semiconductor Materials for TEM Application Note for Leica EM RES102 - The vertical layer construction of a semiconductor structure should be examined as a TEM cross-sectional sample. In addition to the specific preparation of the desired structure, the widely different sputter rates and atomic weights of the individual components represent the level of difficulty involved with this preparation problem. https://www.leica-microsystems.com//science-lab/cross-sectional-preparation-of-structured-semiconductor-materials-for-tem/ Mon, 31 Oct 2016 08:15:00 +0000 PhD Wolfgang Grünewald https://www.leica-microsystems.com/18235 EM Sample Preparation Contrast Enhancement of Polished Cross Sections of Semiconductor Structures - Sample Preparation for SEM Application Note for Leica EM RES102 - The surfaces of polished cross sections often show fine scratches and residues of the removed material or of the abrasive material. The artefacts are strongly material-dependent, and are mostly only detectable at higher resolutions in the scanning electron microscope. A further problem arises from the fact that the ground section mostly only has low contrast, i.e., in the structures of the semiconductor materials are very difficult to discern. With the use of ion beam milling, the ground sections of semiconductor structures can be "contrasted". https://www.leica-microsystems.com//science-lab/contrast-enhancement-of-polished-cross-sections-of-semiconductor-structures-sample-preparation-for-sem/ Fri, 28 Oct 2016 12:08:00 +0000 PhD Wolfgang Grünewald https://www.leica-microsystems.com/17943 Quality Assurance Digital Microscopy Fast and Reliable Inspection of Printed Circuit Boards with Digital Microscopy Digital microscopy has been used more and more for inspection, quality control and assurance (QC/QA), failure analysis (FA), and research and development (R&D) in the microelectronics industry, especially for printed circuit boards (PCBs).

Users in microelectronics quality control seek to identify deviations from the standard and improve the production processes so that defects are minimized or even eliminated. https://www.leica-microsystems.com//science-lab/galleries/image-gallery-digital-microscopy-used-in-microelectronics-and-electronics-quality-control/ Thu, 19 May 2016 11:23:00 +0000 PhD James DeRose, Claudia Müller https://www.leica-microsystems.com/17398 Quality Assurance Digital Microscopy Inspecting and Analyzing Printed Circuit Boards Quickly and Reliably with a Digital Microscope For the past several years, digital microscopy has been shown to be useful for inspection, quality control and assurance (QC/QA), and failure analysis (FA) in the microelectronics industry, especially for printed circuit boards (PCBs).
