A Method to Enhance the Front-Side Lapping Process for Localisation of Sub-Surface Defect for Advanced Packages
Authors: Tan Sze Yee , Wong Chiu Soon , Lo Chea Wee , Goh Cin Sheng 
Published: December 2020

Abstract
In the back-end assembly process, all of the packages will be tested prior to disposition to the customers in order to filter out any device with failure. For a reject unit with an unknown failure mechanism, it will be subjected to a comprehensive failure analysis (FA) to identify the root cause of the failure. Non-destructive verification, following by front-side decapsulation and internal physical inspection is the common way to visualise and identify the physical defect that usually causes the failure of a device during the back-end assembly process. For certain failures, visualization of the defect might not be straight forward after the decapsulation because the defect may be embedded or buried underneath a layer or wedge bond on the die. In this case, a more complicated FA analysis flow which comprises various precision techniques such as parallel lapping, hotspot localisation and focused-ion-beam (FIB) analyses will be needed to thin down the top layer/wedge bond for a precise localisation of the defect prior to precision analysis by FIB. However, the process to thin down the top layer/wedge bond with an exposed die of a partially decapsulated package is a tricky job as artefacts such as crack/scratches on die are likely to be introduced during the process of polishing. Also it is relatively difficult to control the thickness and levelling of the top layer/wedge bond during the thinning process. In this work, we developed a method that allows the analyst to re-cap the partially decapped package, and also to precisely measure and thin down the top layer to an accuracy of less than &lt; 2um without the introduction of artefacts.
Dynamic Photon Emission on FinFET Devices Through Novel Scan Test Approaches
Authors: Gopinath Ranganathan , Venkat Krishnan Ravikumar , Winson Lua , Angeline Phoa , Jie Jin 
Published: December 2020

Abstract
Dynamic Photon Emission Microscopy (D-PEM) is an established technique for isolating short and open failures, where photons emitted by transistors are collected by sensitive infra-red detectors while the device under test is electrically exercised with automated test equipment (ATE). Common tests, such as scan, use patterns that are generated through Automatic Test Pattern Generator (ATPG) in compressed mode. When these patterns are looped for D-PEM, it results in indeterministic states within cells during the load or unload sequences, making interpretation of emission challenging. Moreover, photons are emitted with lower probability and lesser energies for smaller technology nodes such as the FinFET. In this paper, we will discuss executing scan tests in manners that can be used to bring out emission which did not show up in conventional test loops.

Authors: Asano Natsuko , Asahina Shunsuke , Erdman Natasha 
Published: December 2020

Abstract
Voltage contrast (VC) observation using a scanning electron microscope (SEM) or a focused ion beam (FIB) is a common failure analysis technique for semiconductor devices.[1] The VC information allows understanding of failure localization issues. In general, VC images are acquired using secondary electrons (SEs) from a sample surface at an acceleration voltage of 0.8–2.0 kV in SEM. In this study, we aimed to find an optimized electron energy range for VC acquisition using Auger electron spectroscopy (AES) for quantitative understanding.

Published: December 2020

Abstract
The potential benefits and challenges of low kV SEM imaging and EDS elemental analysis have been discussed in the SEM community since at least the early 1990s [1,2]. Concurrent with steady progress in the performance of so-called extreme high-resolution ‘XHR’ SEM imaging [3], is an advancement in low-energy EDS using windowless, large solid angle ‘racetrack’ EDS detectors [4]. As lower kV imaging and EDS analysis becomes accessible, refined models of the interaction of low energy electron beam and real-world samples continues at full speed even today [5].

Published: December 2020

Abstract
In this paper, the stacking fault defects in FinFETs are described as the root cause of the PLL failure. Failure analysis approaches such as photon emission microscopy and nano probing were applied to pinpoint the exact stacking fault location in even transistor level and High resolution TEM confirmed the stacking fault defects in the Fin which was isolated by nano probing. RX local density was confirmed as the key factor in stacking fault generation by TCAD simulation. RX new mask with dummy addition was made to mitigate stress and was confirmed to be effective to reduce the compressive strain at the channel in FinFETs by Geometric Phase Analysis (GPA) which provided sufficiently practical local strain measurement data. The GPA techniques demonstrated here are informative for process improvement and failure analysis in FinFET devices.

Robust Test Method of TSOP PEMs for Space Application
Authors: Iwai Yasunobu , Shinozaki Koichi , Tanaka Daiki 
Published: December 2020

Abstract
Compared with space parts, consumer parts are highly functional, low cost, compact and lightweight. Therefore, their increased usage in space applications is expected. Prior testing and evaluation on space applicability are necessary because consumer parts do not have quality guarantees for space application [1]. However, in the conventional reliability evaluation method, the test takes a long time, and the problem is that the robustness of the target sample can’t be evaluated in a short time.
In this report, we apply to the latest TSOP PEM (Thin Small Outline Package Plastic Encapsulated Microcircuit) an evaluation method that combines preconditioning and HALT (Highly Accelerated Limit Test), which is a test method that causes failures in a short time under very severe environmental conditions. We show that this method can evaluate the robustness of TSOP PEMs including solder connections in a short time. In addition, the validity of this evaluation method for TSOP PEM is shown by comparing with the evaluation results of thermal shock test and life test, which are conventional reliability evaluation methods.
Deep drawing of a stellar shape using finite element simulation and experimental
Authors: Khalid Jawad Waleed , T. Ikal Ali 
Published: December 2020

The process of deep drawing of complex shapes is a difficult process compared to the process of drawing simple shapes such as cylindrical, square and rectangle because of the complex shape is subjected to the higher stresses concentration compared to simple shapes. This work aims to study the effect of the wall corner radius of punch and radial clearance on deep drawing operation using the experimental work and numerical simulation. In this work, an analysis of the deep drawing process is performed for process design of stellar cup drawing. A deep drawing die was designed and manufacturing to perform the experimental procedure required to produce a stellar cup with inner dimensions (major axis equal to 43.7 mm and minor axis equal to 36.64 mm) formed from a circular flat sheet (80 mm diameter) comprised of low carbon steel of (0.08%) carbon content, without any intermediate annealing. A commercially finite element program code (ANSYS 18.0) is utilized to simulate the stellar deep drawing operation. From the comparison between the results, it has been found that the thinning at cup corner increases by decreasing the wall corner radius of the punch and the maximum thinning with the wall corner radius of the punch equal to ( 16Rcp'> = 2 mm) at the corner of the minor axis of completely drawn cup

BACKGROUND: Long-non-coding RNAs, a class of transcripts with lengths > 200 nt, play key roles in tumour progression. Previous reports revealed that LINC00052 (long intergenic non-coding RNA 00052) was strongly downregulated during breast cancer multicellular spheroids formation and suggested a role in cell migration and oxidative metabolism. OBJECTIVE: To examine the function of LINC00052 in MCF-7 breast cancer cells. METHODS: Loss-of-function studies were performed to evaluate LINC00052 role on MCF-7 breast cancer cells. Microarray expression assays were performed to determine genes and cellular functions modified after LINC00052 knockdown. Next, the impact of LINC00052 depletion on MCF-7 cell respiration and migration was evaluated. RESULTS: 1,081 genes were differentially expressed upon LINC00052 inhibition. Gene set enrichment analysis, Gene Ontology and Key Pathway Advisor analysis showed that signalling networks related to cell migration and oxidative phosphorylation were enriched. However, whereas LINC00052 knockdown in MCF-7 cells revealed marginal difference in oxygen consumption rates when compared with control cells, LINC00052 inhibition enhanced cell migration in vitro and in vivo, as observed using a Zebrafish embryo xenotransplant model. CONCLUSION: Our data show that LINC00052 modulates MCF-7 cell migration. Genome-wide microarray experiments suggest that cancer cell migration is affected by LINC00052 through cytoskeleton modulation and Notch/β-catenin/NF-κB signalling pathways.
Additive DenseNet: Dense connections based on simple addition operations
Authors: Yu Dawei , Yang Jie , Zhang Yun , Yu Shujuan 
Published: December 2020

The Densely Connected Network (DenseNet) has been widely recognized as a highly competitive architecture in Deep Neural Networks. And its most outstanding property is called Dense Connections, which represent each layer’s input by concatenating all the preceding layers’ outputs and thus improve the performance by encouraging feature reuse to the extreme. However, it is Dense Connections that cause the challenge of dimension-enlarging, making DenseNet very resource-intensive and low efficiency. In the light of this, inspired by the Residual Network (ResNet), we propose an improved DenseNet named Additive DenseNet, which features replacing concatenation operations (used in Dense Connections) with addition operations (used in ResNet), and in terms of feature reuse, it upgrades addition operations to accumulating operations (namely ∑ (·)), thus enables each layer’s input to be the summation of all the preceding layers’ outputs. Consequently, Additive DenseNet can not only preserve the dimension of input from enlarging, but also retain the effect of Dense Connections. In this paper, Additive DenseNet is applied to text classification task. The experimental results reveal that compared to DenseNet, our Additive DenseNet can reduce the model complexity by a large margin, such as GPU memory usage and quantity of parameters. And despite its high resource economy, Additive DenseNet can still outperform DenseNet on 6 text classification datasets in terms of accuracy and show competitive performance for model training.

The global economic crisis, which is linked to the coronavirus pandemic, has also affected pharmaceutical logistics. Therefore, the improvement of logistics processes within the pharmaceutical supply chain to increase the access to health care to the population in a pandemic becomes especially important.
The aim of the work is to study and summarize the main problems of pharmaceutical logistics in a coronavirus pandemic and substantiate the reserves to improve the functioning of pharmaceutical supply chains.
To achieve the goal of the study, an analysis of the domestic scientific literature and the current regulatory framework of Ukraine was conducted. It has used abstract-logical, monographic research methods and system analysis, as well as the method of expert survey.
Realizing the importance of providing the population with necessary medicines during the pandemic in Ukraine on October 14, 2020, the Law «Changes to the article 19 of the Law of Ukraine "On Medicinal Products" on Electronic Retail Trade in Medicines» of September 17, 2020 № 904-IX has enforced.
It has been evaluated the factors influencing the efficiency and coordination of the activities of pharmaceutical supply chain participants. A risk management algorithm for pharmaceutical supply chains has been developed, its structural elements and relationships have been identified. The presented algorithm will allow analyzing and estimating any deviations from the planned parameters in pharmaceutical supply chains on the basis of establishment of system of the corresponding indicators and on the basis of this information to define effective methods to counter the risks.
The urgency of the problem of increasing the reliability and safety of domestic pharmaceutical supply chains in a pandemic has proved. It is justified that the introduction of digital technologies will increase the reliability, transparency and quality of business processes in the pharmaceutical supply chains during a pandemic, drastic changes in the pharmaceutical market and low predictability of demand for medicines and medical devices. The main problems of logistics in a pandemic in the domestic pharmaceutical industry are studied. It has established that the narrowest places in the organization of pharmaceutical supply chains are the improper organization of information exchange between pharmaceutical supply chain participants and the insufficient professional level of production interaction of managers. It has established the priority directions of increase of stability and reliability of functioning of pharmaceutical supply chains which is a necessary condition of accessibility of pharmaceutical provision of the population, especially in the conditions of a pandemic.

Published: December 2020

Background: Hemorrhagic transformation after acute ischemic stroke is a dreaded and severe complication of thrombolysis and thrombectomy. However, its detection on post-thrombectomy conventional non-contrast computed tomography (CT) scan can be complicated by the frequent (and sometimes concomitant) presence of contrast, resulting in changes in management.Aims: Our objective was to assess the inter- and intra-rater reliability for the detection of blood and/or contrast on day-1 post-thrombectomy CT scans.Methods: A total of 18 raters across 3 different specialties independently examined 30 post-thrombectomy CT scans selected from the Aspiration vs. STEnt-Retriever (ASTER) trial. They were asked to judge the presence of blood and contrast. Thirty days later, the same 18 raters again independently judged the 30 scans, in randomized order. Agreement was measured with Fleiss' and Cohen's K statistics.Results: Overall agreement on blood and/ or contrast presence was only fair, k = 0.291 (95% CI = 0.273–0.309). There were 0 scans with consensus among the 18 readers on the presence of blood and/or contrast. However, intra-rater global agreement across all 18 physicians was relatively high, with a median kappa value of 0.675. This intra-rater consistency was seen across all specialties, regardless of level of training.Conclusion: Physician judgment for the presence of blood and/or contrast on day-1 post-thrombectomy non-contrast CT scan shows limited inter-observer reliability. Advanced imaging modalities may then be warranted for challenging clinical cases.

Satuan stratigrafi dari karbonat tebal akibat siklus sedimen yang terendapkan di wilayah Zagros pesisir selatan Neotitis, Iran dikenal dengan formasi Sarvak sebagai rangkaian karbonat yang tersusun atas batuan sedimen non – klastik sebagai penghasil hidrokarbon yang signifikan. Perbedaan nilai vp yang didapat pada tiap lapisan membuat penelitian ini ingin mengetahui kisaran nilai impedansi akustik pada lapisan karbonat formasi sarvak dengan Persamaan Gassman dan juga Differential Effective Medium (DEM). Gassman yang digunakan secara luas dalam industri minyak dan gas dapat mengidentifikasi fluida serta pemantauan reservoir, sedangkan Differential Effective Medium (DEM) dapat memprediksi sifat elastis batuan agregat berpori pada semua jenis batuan tanpa asumsi spesifik seperti Gassman. Pengukuran kecepatan gelombang P batuan karbonat menggunakan alternatif lain (metode DEM) akibat asumsi Gassman yang tidak valid. Setelah didapat nilai kecepatan gelombang P pada formasi Sarvak, kisaran nilai impedansi pada tiap lapisan didapatkan. Kisaran tersebut dapat mengidentifikasi litologi lapisan formasi Sarvak menggunakan klasifikasi tabel 1 dan 2. Pada praktiknya, klasifikasi menurut tabel 1 dan 2 tidak sinkron hanya dengan salah satu indikator yaitu vp saja atau impedansi akustik saja, sehingga dibutuhkan penelitian lanjutan untuk mengetahui karakterisasi batuan penyusun litologi menggunakan software AVO, data log, serta parameter pendukung lainnya seperti EEI (Extended Elastic Impedance).

Cet article montre comment, dans la pensée de Jean-Louis Déotte, les notions centrales d’appareil (compris aussi comme condition d’apparaître) et de disparition sont liées. C’est la disparition des corps, dans le cadre d’une stratégie d’oubli organisée par certains régimes, et aussi la structure spectrale peut-être inhérente à toute technique de représentation depuis la perspective albertienne et jusqu’au cinéma, qui sont en jeu. La spectralité permet ainsi d’envisager de manière originale les rapports entre arts, techniques et politique.
