Published: August 2023

The Chemical Mechanical Planarization (CMP) process (polishing and substrate cleaning) results in defects that can be classified as mechanical (i.e., scratching), chemical (i.e., corrosion), or physiochemical (i.e., adsorbed contaminants) according to the mechanism of formation. This work will focus on the rationale design of p-CMP cleaning systems for emerging materials (silicon carbide (SiC)) that activate the cleaning chemistry via external stimuli such as megasonic energy. More specifically, using megasonic energy in the presence of supramolecular assemblies such as micelles and vesicles was employed for a “soft” (low shear force) defect removal process. Results indicate a correlation between the structure of the “soft” cleaning additives and induced megasonic energy on overall simulated defect removal. It was determined that effective particle removal was a second-order kinetic process with a concentration dependency (i.e. above and below the critical micelle concentration (CMC)) emerging as a key driver for the defect removal rate. Although, one apparent drawback is the generation of post-cleaning carbon residue due to the adsorption of the supramolecular structures to the SiC substrate.
Silicon Nitride Selective Functionalization with Aqueous Cellulose
Authors: Mochida Kenji
Published: August 2023

In semiconductor device manufacturing, it is often necessary to process devices that incorporate both Si3N4 and SiO2 with etching solutions. Recently, we found that a cellulose-based polymer (DC01) selectively adsorbs onto silicon nitride and acts as a protective film against etching with buffered fluoric acid. However, the mechanism behind this selective adsorption remains unclear, and a protective film persists after etching. QCM measurements and calculations of the surface free energy indicate that the affinity between DC01 and Si3N4 was significantly stronger than that of SiO2. Notably, the same behavior was not observed with cellulose or cellulose acetate, indicating that this phenomenon is unique to our original cellulose. Additionally, we successfully prepared films using a facile dipping method. Furthermore, we discovered that the strongly adhesive DC01 film can be completely removed by subjecting it to oxidative conditions, such as SC-1 or SC-2.

The semiconductor industry is a significant consumer of water and chemicals. In particular, water is a valuable resource, and its efficient use is crucial to ensure availability for future generations. By implementing measures to reduce water and chemical consumption, the semiconductor industry can minimize its environmental footprint and contribute to sustainability efforts. Technology for the recycling of unused hot ultrapure water (H-UPW), ozonated water and reclaimed sulfuric acid-hydrogen peroxide mixtures (SPM) has been developed and installed in high-volume manufacturing (HVM) semiconductor manufacturing facilities. This paper presents an overview of the technology and expected savings in water, sulfuric acid and energy consumption from the implementation of these technologies.

Published: August 2023

We demonstrate that a uniform recess of polycrystalline Mo can be achieved using a two-step method: metal oxidation with isotropic oxygen plasma that forms a layer of MoO3 and selective etching of this oxide layer. The oxidation step fully defines the recess depth, and its uniformity is ensured by the low facet dependence of plasma oxidation. We have extensively studied the oxidation of patterned Mo nanowires (30 nm width) in isotropic oxygen plasma and achieved uniform oxide layers of predefined thickness by controlling radio-frequency (RF) power, gas pressure, and exposure time. We showed that using highly selective oxide etching, we can perform multiple etching cycles with a typical etch rate of 1-2 nm per cycle, depending on the RF power. Due to plasma isotropy, this approach can be implemented for a controlled uniform etching of large vertical stacks of metal nanostructures.
Investigation of Oxide Regrowth in the Selective Si3N4 Etching Process for 3D NAND Fabrication by Using Finite Element Modeling Simulation
Authors: Kim Tae Hyeon , Lee Yu Seok , Han Jong Won , Lim Sang Woo
Published: August 2023

In the process of manufacturing three-dimensional Not AND (3D NAND) flash memory devices, oxide regrowth occurs during the selective Si3N4 etching process on the Si3N4/SiO2 multi-stack structures. The oxide regrowth issue must be suppressed. Thus, effects of two factors, the mass transfer ability of etching byproduct and the stack number of 3D NAND structure, on oxide regrowth were investigated in this study using finite element method (FEM) simulation. Using FEM simulation, we predicted that increase in the stack number of the 3D NAND structure and decrease in the diffusivity of Si3N4 etching byproducts highly aggravated the oxide regrowth. Therefore, it was suggested that an etchant capable of promoting H2SiO3 diffusion behavior would inhibit the oxide regrowth during the selective Si3N4 etching process of the 3D NAND structure.

Published: August 2023

In this paper, we investigate the use of a wet cleaner developed to dissolve residues left after plasma etching selectively to aluminum in new applications such as the removal of various resilient ionic and halides-based surface contaminants. The compromise between efficiency and selectivity of this fluorinated acid cleaner makes it an interesting chemistry for many cleaning steps during wafer manufacturing. Two new applications were investigated: the selective removal of fluoride-based defects on aluminum pads and surface decontamination of various ionic metals with low substrate consumption. These studies showed very encouraging results in beakers level tests, but also on partly industrial equipment, opening new possibilities for this cleaner. Indeed, “water lily” defects removal seems to be possible with a low aluminum consumption in TechniClean IK73. Decontamination study carried out in static bath and in single wafer tool showed rather similar results, enabling static bath protocol and ionic metals removal to be validated and VPD-ICPMS results, after a short process time in a single wafer tool were very promising with metal levels close to the lower limit of detection of all elements tested.
Development of Intentional Contamination in Iron by Bath for Silicon Wafers and Evaluation of VPD-Bulk and LPD-Bulk for Metallic Contaminants Analyses by ICPMS
Authors: Yim Viviane , Truffier-Boutry Delphine , Mukhtarov Anna , Galtayries Anouk
Published: August 2023

This paper offers a preliminary study for the analysis of metallic contamination on front-end patterned wafers obtained by two different techniques based on the etching of the whole patterns, LPD-Bulk and VPD-Bulk coupled with an ICPMS. To elaborate the analysis of patterned wafers, methods were first verified and optimised on reference Si wafers. Both techniques are complementary methods for the etching of wafers. LPD-Bulk enables a fast etching of several micrometres of Si but with less precision than VPD-Bulk, which is more adapted for the etching of layers thinner than 1 micrometre. The intentional contamination in SC1 and H2O bath of monitoring wafers showed that contamination in H2O is better controlled due to the absence of chemical reactions, competition between oxidation and etching processes occurring during SC1. And diffusion of contaminants at the tested temperatures from 20°C to 80°C, does not occur. Heat treatment should be applied to allow the diffusion of metallic contaminants in the bulk of the wafers.

Authors: Seike Yoshiyuki , Suzuki Hiroharu , Ichino Yusuke , Mori Tatsuo
Published: August 2023

In the manufacture of semiconductor chips, the cleaning process is an important process. A two-fluid spray is used in single-wafer cleaning. However, two-fluid spray cleaning has the problem of electrostatic discharge (ESD) on devices on the wafer. In this study, we measured the current generated by two-fluid spraying of pure water using a prototype Faraday cage. We also measured the velocity and size of flying droplets using a shadow doppler particle analyzer (SDPA) to clarify the relationship between the generated current and flying droplet characteristics. As a result, it was confirmed that the current generated during two-fluid spraying shows positive polarity and that the amount of droplet charge increases as the flying droplet velocity increases. To reduce ESD generated during two-fluid spray cleaning, we have confirmed that the amount of electrification of pure water droplets can be controlled by installing an induction charging device immediately after the injection of pure water.

Published: August 2023

Fluorinated chemistries can lead to severe corrosion damage towards silicon and germanium based materials when wafers have a significant amount of electrostatic charges. This corrosion is evidenced on both single wafer and batch tools. It can be prevented by the presence of enough light, and wafer charging can also be eradicated by photo emission with UV light.

Published: August 2023

Ultrahigh vacuum (UHV) environment has been widely used in surface science, but UHV technology has been often considered too complex and expensive methodology for large-scale industrial use. Because the preparation of atomically smooth and clean Si surfaces has become relevant to some industrial processes, we have re-addressed the question if UHV could be utilized in these surface tasks using industrially feasible parameters. In particular, we have studied how UHV treatments might be combined with the widely used semiconductor cleaning methodology of wet chemistry.
Methods for Uniform Wet Etching in Narrow Trenches and Vias

Published: August 2023

Abstract. Advanced semiconductor technology features complicated three-dimensional nanostructures and nanoconfined spaces such as nanosheets, supervias, deep contact holes and nanocavities. Uniform wet etching of such nanoconfined spaces across different feature sizes or critical dimensions (CD) is extremely challenging. Typically, etch rate decreases with decrease in CD size. In this paper we report methods to achieve uniform wet etch rate (ER) of SiO2 across different CD sizes by mixing organic solvents in the etching solution. We also report a reversal of etch rate trend where SiO2 structure of smaller CD etches faster than a larger CD, by tuning the ratio of organic to water solvents in the etching solution. We also investigate the impact of parameters such as solvent type, wall material, surface tension and ionic strength on ER. Our data suggests, while surface tension and ionic strength show no impact, the type of wall material, surface potential and organic solvent amount in the etching solution show a strong influence on SiO2 ER. Also, zeta potential could explain most of our results but not all, suggesting that surface potential is not the only factor impacting CD dependent ER in a nanoconfined spaces.

Published: August 2023

A quarter of children with Specific Learning Disorder (SLD) have a comorbid attention deficit hyperactivity disorder (ADHD), which impacts the testing of intelligence. ADHD is therefore treated before proceeding with the assessment of intelligence. It is expected that the treatment of ADHD will mitigate its effects on intelligence testing. Though this is frequently done in clinical practice, we could not find any study comparing IQ profiles of children having SLD with and without ADHD after treating ADHD to look for any changes between them. Therefore, we planned this study to compare the cognitive profiles of children having SLD with and without ADHD and describe any difference in their profiles. It was a retrospective cross-sectional study. We compared 695 children having SLD with treated ADHD to 721 children having SLD without ADHD on their WISC III profiles. We found that children having SLD with treated ADHD scored significantly lower on Digit Span and Coding. We suggest routine use of Cognitive Working Memory Training, peer tutoring, and task modifications in children having SLD with ADHD along with medicines and remedial education for better outcomes.

Kecerdasan adalah tingkat kemampuan anak untuk berpikir kritis dalam menyelesaikan masalah yang dihadapi. Kemampuan tersebut terdapat dalam berbagai bidang karena kecerdasan anak bermacam-macam sesuai keahlian di bidangnya masing-masing. Umumnya, pada anak terdapat beberapa kecerdasan itu diantaranya kecerdasan bahasa linguistik, logis-matematis, visual-spasial, kinestetik, interpersonal, intrapersonal, musikal, dan naturalis. Dimana berbagai macam kecerdasan itu disebut dengan kecerdasan jamak (multiple intelligences). Tetapi proporsi tingkat kecerdasan setiap anak pasti tidak sama, tergantung pada stimulasi yang anak dapat dan tergantung pada faktor-faktor yang mempengaruhi kecerdasan anak tersebut. Namun, faktor-faktor yang bersifat tetap atau internal secara alami ada pada diri anak masih bisa diatasi dengan pemberian stimulasi dari luar, yaitu pemberian kegiatan-kegiatan diluar adanya faktor internal. Oleh karena itu, tujuan dari jurnal ini yaitu agar dapat membantu pendidik dalam menciptakan hal yang kreatif melalui kegiatan stimulasi guna mengembangkan kecerdasan jamak pada diri anak.

Published: August 2023

This article explores the possibilities of a cheap one-dollar microscope, the Foldscope, for enhancing out-of-school science education. Developed by Manu Prakash and Jim Cybulski from Stanford University, these origami-type paper microscopes make it possible to provide all students with their own microscopes, due to the low cost. This provides students the opportunity to engage in science outside of the classroom, as amateur sleuths engaged in environmental inquiries, e.g., determining the levels of pollution of local water resources. In this article the authors share two sets of research data: an activity where school students engaged in authentic problem-based learning using the Foldscopes, as well as student teachers’ experiences of engaging with Foldscope microscopes. The outcomes of the first research project indicate that affective outcomes and cognitive gains were achieved. Responses in the second research project included five categories: preparation and presentation; potential of the Foldscope; use of slideshow; energy/complements; and limitations. The conclusion reached was that Foldscopes hold possibilities for enhancing STS (science-technology-society) approaches inside and outside the classroom. One recommendation is that such frugal-science approaches are emphasized more in both pre-and in-service teacher education.

Numeracy and digital skills are among the most crucial skills that any graduate should possess before entering the workforce, regardless of their field of study.  Therefore, both skills should not be treated as an “add on” skill but viewed as essential graduate attributes needing to be purposefully incorporated into the curriculum instead of mere chance. By understanding the learners’ numeracy and digital skills abilities, educators can create suitable learning outcomes, activities, and assessments, enabling them to acquire the skills. The objective of this study is to create a framework for testing numeracy (NSI) and digital skills (DSI) using a cross-sectional design and quantitative methodology. The research entails generating a questionnaire, verifying it via a rigorous procedure of expert content validation, and focusing on sufficiency, clarity, coherence, and relevance.  A pilot study involving 218 students from various disciplines was conducted to measure the reliability of the framework using Cronbach Alpha. Feedback from experts was then used to enhance the questionnaire, resulting in the finalisation of five components for the Digital Skills Instrument (DSI): information literacy, computer and technology literacy, digital communication and collaboration skills, digital identity and well-being, and digital ethics. Meanwhile, the five components of the Numeracy Skills Instrument (NSI) encompassed operation and calculation, graphical representation, quantitative reasoning and logical thinking, complex number (advanced concept), spatial visualisation and geometric reasoning. The results indicated a strong internal consistency across all components for both tools, with alpha values ranging from 0.847 to 0.958 for DSI and 0.916 to 0.964 for NSI. Corrected item-total correlations also depicted intercorrelation between items for both instruments. To sum up, the findings demonstrate that the DSI and NSI have high reliability and validity. Because both tools are reliable and valid for measuring digital and numeracy skills in the Malaysian context, they can be confidently used for future research.
A dataset and template for assessing the ecological status of marine sediments and waters, based on microbial taxa
Authors: Borja Angel
Published: August 2023

Microbes have often been overlooked as indicators of how the ecological status is affected by human pressures. Recently, the biotic index microgAMBI was proposed to assess the status of marine sediments and waters, and it has been tested under different pressures and biogeographical areas. This index is based on the assignation of microbial taxa to one of two ecological groups: sensitive or tolerant to pollution or disturbance. The resulting taxa list has grown significantly since its first publication. Given the growing use of microgAMBI, it is crucial to make it more FAIR: Findable, Accessible, Interoperable and Reusable. Hence, this work provides the calculation template, the updated taxa list (1,974 taxa currently), and instructions on how to access and use them for assessing marine microbial ecological status.

This paper aims to review the performance of different machine learning (ML) models and develop models for the automated diagnosis of chronic kidney disease. To detect chronic kidney disease with better precision, selecting the right and better-performing ML model is significant as it improves the precision and accuracy of the chronic kidney disease diagnosis. The study uses the Joana Briggs Institute (JBI) scoping review methodology, which involves different steps such as searching relevant literature, conducting the review, and reporting the review result. In the search, the year of publication and the indexing of journals where the studies are published is used as inclusion and exclusion criteria. The review result shows that the current chronic kidney disease detection has focused on the development of ensemble-based and deep-learning methods. The deep learning method can achieve a higher accuracy of 99.75%.
Spokes of the Same Wheel: How Collaboration Between Resource Providers Impacts Outcomes for Female Small Business Owners in Western North Carolina

Published: August 2023

Female small business owners face numerous hurdles to maintaining and growing their firms and these barriers have become increasingly difficult to surmount in the wake of the Covid-19 pandemic. While small business resource providers deliver needed funding and technical assistance, the perspectives and experiences of female small business owners are often missing from dialogues regarding the efficacy of local small business ecosystems. Interviews reveal that while female clients of the Western Women’s Business Center (WWBC) benefit from the program’s services – including business coaching, community events, and access to capital – some of the BIPOC and Spanish-speaking small business owners that were interviewed feel alienated from the resource provider community more broadly. Although collaboration between resource providers maximizes available services, increases their quality, and minimizes redundant offerings, organizations must employ a culturally competent, linguistically accessible approach to effectively serve marginalized populations.
Safety Assessment: Outcome of assessment of Cetylated Fatty Acids as a Novel Food
Authors: Risk Assessment FSA Regulated Products
Published: August 2023

An application was submitted to the Food Standards Agency (FSA) and Food Standards Scotland (FSS) in February 2021 from Pharmaneutra S.p.a., Italy (“the applicant”) for the authorisation of cetylated fatty acids as a novel food. The novel food is a mixture of cetylated fatty acids, cetyl myristate and cetyl oleate, which are synthesised from cetyl alcohol with myristic acid and, cetyl alcohol with oleic acid, respectively. These two cetylated fatty acids are then blended with olive oil to give a finished product containing 70 – 80% cetylated fatty acids. The application is a new application, seeking to use cetylated fatty acids within the food category: food supplements. To support the FSA and FSS in their evaluation of the application, the Advisory Committee on Novel Foods and Processes (ACNFP) were asked to review the safety dossier and supplementary information provided by the applicant. The Committee concluded that the applicant had provided sufficient information to assure the novel food, cetylated fatty acids, was safe under the proposed conditions of use. The anticipated intake levels and the proposed use in foods and food supplements was not considered to be nutritionally disadvantageous and does not mislead consumers. The views of the ACNFP have been taken into account in this safety assessment which represents the opinion of the FSA and FSS on cetylated fatty acids.
