Fan-out Wafer and Panel Level Packaging are gaining relevance as high-volume-compatible advanced packaging technologies. Providing technical advantages and optimized cost for manifold applications, FOWLP and PLP are fundamentally changing the packaging infrastructure. In the past, OSATs dominated high-volume manufacturing, but recently new players in packaging such as semiconductor foundries, PCB or LCD manufacturing companies entered this business area and are changing not only supply chains but also form factors towards larger areas. However, materials are playing an important role especially for future applications such as RF, power or advanced computing applications. In addition, materials are also a key factor for cost and sustainability. In summary, the presentation will discuss recent technical developments as well as the changing ecosystem and actual advantages and challenges when moving to large-panel-level manufacturing.

Plastic production has outgrown most other manmade materials, with more than 99% of them being petroleum-based and nonbiodegradable. Conventional plastics are difficult to recycle and persist in the environment for hundreds of years, causing great environmental concerns. In addition, the dependence on crude oil makes the plastics industry unsustainable and renders the plastics market vulnerable to oil price volatility. Therefore, there is a growing interest in developing sustainable alternatives to conventional plastics. Particularly, the electronics industry is making a switch to greener alternatives to reduce greenhouse gas emissions, lower product environmental footprints, and build positive marketing image. Here, we present a perspective on the advancement of bioplastic sustainable alternatives and the challenges and advantages associated with their potential use in electronics.

This presentation will focus on the new trajectory for Si packaging technology set by the emergence of AR/VR hardware and advanced wearable computing. We believe the next major step beyond handheld computing will be wearable computing in the form of novel, hands-off and all-day wearable AR/VR devices like AR glasses. These devices will continue the remarkable journey of miniaturization and power/performance carved out by its predecessors. We will discuss the complex array of Si and packaging technologies that lie “under the hood” of such devices, spanning these three areas: Augmented Reality Processing (ARP), Display and Imaging (D&I), and Low-energy Wireless (LW) communication. We will demonstrate unique approaches that combine advanced packaging technologies like flip chip, fan-out wafer-level packaging and TSVs, often within the same package. Finally, we will discuss the challenges created by the need to spawn new ecosystems such as heterogeneous integration and fabrication methods that often fall in the grey zone between Foundry and OSAT.

IEEE 802.11be, which is also known as Wi-Fi 7, is the next amendment to the IEEE 802.11 standard for wireless local area networks (WLAN). This amendment is anticipated to greatly enhance the performance of indoor and outdoor WLAN operations at both stationary and pedestrian speeds in the 2.4, 5, and 6 GHz frequency bands. Wi-Fi 7, also called Extremely High Throughput (EHT), is set to provide multi-gigabit Wi-Fi with faster speeds, less interference, and better performance for high-bandwidth online activities. The new standard is expected to achieve a theoretical maximum speed of 30 Gbit/s, which is a significant improvement from the previous standard, IEEE 802.11ax. In this talk, Laurent Cariou will deliver a high-level overview of the features that are defined in the upcoming standard. Additionally, he will briefly introduce the next activity in 802.11, known as Ultra High Reliability (UHR), which is expected to become Wi-Fi 8. Biography Laurent Cariou earned his Ph.D. in electronics from the National Institute of Applied Sciences in Rennes, France in 2003 and 2006, respectively. He has spent over a decade working in IEEE 802.11 and currently serves as Intel's principal engineer and technical lead for mainstream Wi-Fi in 802.11. Cariou played a key role in establishing the High-Efficiency WLAN (HEW) group that eventually led to the development of 802.11ax and Wi-Fi 6. Recently, he also initiated the Extremely High Throughput (EHT) activity. Currently, Cariou holds the position of vice-chair for the 11be/EHT task group (Wi-Fi 7) and is also the chair for the Ultra-High Reliability (UHR – Wi-Fi 8) study group.

Meanwhile, many organizations (such as national parks, vacation resorts, departments of transportation) provide real-time visual data (images or videos). These videos allow Internet users to observe events remotely. This speech explains how to discover real-time visual data on the Internet. The discovery process uses a crawler to reach many web pages. The information on these web pages are analyzed to identify candidates of real-time data. The data is downloaded multiple times over an extended time period; changes are detected to determine whether it is likely to provide real-time data. The data can be used during an emergency. For example, viewers may check whether a street is flooded and cannot pass. It is also possible using the data to observe long-term trends, such as how people react to movement restrictions during the COVID pandemic. Speaker(s): Dr Lu, Vishnu S.

presented by Dr David Ress, Baylor College of Medicine where he is the Technical Director of the Center for Magnetic Resonance Imaging. Abstract: The human brain exhibits a close relationship between neuronal electrical activity and blood flow. The phenomena, functional hyperemia, is the basis for functional magnetic resonance imaging (fMRI). In particular, a brief (~2 s) period of electrical activity evokes a stereotypical fMRI response that is often called the hemodynamic response function (HRF). Our laboratory has developed experimental methods, consisting of an audiovisual stimulus together with a speeded task, to evoke reliable HRFs across the majority of cerebral cortex in a single, hour-long fMRI scanning session. The resulting spatial pattern of response amplitudes is very similar across subjects. In healthy young subjects, the temporal dynamics of the HRFs vary only modestly across cortex. However, the dynamics show significant changes with aging possibly associated with cardiovascular changes. We have also developed a simple model for the HRF based on a linear network approximation to the vasculature, coupled with a 1.5D convection-diffusion treatment of oxygen transport. The model provides a quantitative interpretation of the HRF in terms of blood flow and cerebral oxygen metabolism. Our goal is to utilize these experimental and modeling methods as a means to diagnose various forms of brain pathology.

Hybrid Meeting On-line and In Person at Quadrant Refreshments will be available at Quadrant prior to the start of the presentation. Research on curvature effects in magnetic nanostructures is attracting much interest as they offer novel alternatives to planar systems. In particular, the cylindrical geometry introduces significant singularities in the magnetic response of ferromagnetic wires just from their curvature, which primarily depends on their diameter, length, and aspect ratio. The main magnetic configurations include axial, transverse, and vortex (circular with a singularity at the axis). Micrometric-diameter amorphous wires with high magnetostriction re-magnetize through an ideal millimeter-long single domain wall propagating at kilometer-per-second speeds that results in a square hysteresis loop. Such bistable behavior and their magnetoelastic properties are the basis for various devices (e.g., stress and temperature sensors, electromagnetic shielding). On the other hand, ultrasoft non-magnetostrictive microwires are employed in very sensitive field sensors based on their giant magnetoimpedance effect or in flux-gate magnetometers. Nanowires (20 nm to 400 nm in diameter) present an outstanding behavior where the crystalline structure plays a major role in competition with shape anisotropy. Cylindrical nanowires are considered as scaffolds for advanced three-dimensional nanoarchitectures exploiting intrinsic curvature that introduces significant differences from planar-based nanotechnologies. They are proposed for novel sensor devices and magnets, and their interconnecting arrays are considered for energy devices or brain-inspired computing. An ultimate goal is currently the investigation of the magnetization reversal modes in individual nanowires by advanced techniques, e.g., X-ray magnetic circular dichroism (XMCD) coupled to photoemission electron microscopy (PEEM), magnetic force microscopy (MFM), magneto-optical Kerr effect (MOKE), electron holography, and micromagnetic simulations. They show axial, transverse, vortex, and more complex, exotic magnetic configurations and effects (e.g., magnetization ratchets, skyrmion tubes, helical vortices). The reversal nucleates at the nanowire ends involving singularities (e.g., Bloch-point walls) and at local transition regions (e.g., modulations in diameter and compositional modulations between segments of differently designed magnetic properties, such as ferromagnetic/ferromagnetic (FM/FM) or ferromagnetic/nonmagnetic (FM/NM). Individual nanowires are currently used or proposed for biomedical applications, such as cancer treatment, magnetic resonance imaging (MRI) contrast agents, or in composites for their antimicrobial activity.

Abstract: Wideband digital active electronically scanned array systems require protection at each element against RF interference to avoid saturation of components. Such protection is offered by high performance RF filters of physical dimension that fit within the elemental spacing of the array. The COmpact Front-end Filters at the ElEment-level (COFFEE) program leverages material breakthroughs to create compact RF filters of differentiating device performance. Through COFFEE, new advances in dipole engineering of piezoelectric thin films while controlling crystallinity and composition have led to acoustic resonators, a fundamental building block of filters, with record breaking coupling coefficients and quality factors at 18 GHz and 50 GHz. Moreover, simulations of new magnetostatic filter designs enabled by newly developed ferrite processing and integration show state-of-the-art tunability in the range of 2‑18 GHz and 45‑50 GHz. COFFEE’s material developments are complemented by circuit-based approaches such as N-path and evanescent cavity filters. The diverse approaches within the COFFEE program are fighting physics against physics to determine the most promising technologies for the next generation of compact, high frequency filters with low loss and high-power handling.

Two-dimensional materials hold great promise for future nanoelectronics. Their atomic thickness enables highly scaled field-effect transistors with reduced short-channel effects and relatively high carrier mobility. In this presentation, the electrical and optical properties of 2D transition metal dichalcogenides (TMDs such as MoS 2 , WSe 2 , ReSe 2 , PtSe 2 , and PdSe 2 ), GeAs, and black phosphorus are discussed. The intrinsic electrical transport properties of 2D materials are commonly investigated using back-gated field-effect transistors, due to the low density of process-induced defects and the easy fabrication. Electrical transport, modulation of the conductivity by a back-gate, effect of electron irradiation, environmental pressure and surface adsorbates, and photoresponse are investigated in TMD nanosheets obtained by either mechanical exfoliation or chemical vapor deposition on SiO 2 /Si substrates. It is shown that the contact resistance can be tuned by electron irradiation, which reduces the Schottky barrier and improves the 2D material/metal contact. It is demonstrated that adsorbates can change the polarity of the charge carriers and enhance the hysteresis in the transfer characteristics of TMD-based field-effect transistors. It is reported that several 2D materials exhibit strong photoresponse due to their direct bandgap and density of states that favour the interaction with light. Time-resolved photocurrent measurements demonstrate that many 2D based devices exhibit slow or persistent photoresponse that is attributed to intrinsic or extrinsic trap states, photobolometric effect and desorption of adsorbates. It is highlighted how positive and negative photoconductivity can coexist in the same 2D-based device, the dominance of one type over the other being controlled by O 2 and H 2 O adsorbates. The strong dependence of the channel conductance on electrical stress, air pressure, gas type, and light make 2D materials-based devices suitable for memory, gas, and light sensing applications. Finally, as the tunable conductivity and the sharp-edge geometry facilitate the extraction of electrons under the application of an electric field, it is proved that several 2D materials are also effective field emitters and that their emission current can be modulated by a back-gate.

Hybrid Meeting On-line and In Person at Quadrant Refreshments will be available at Quadrant prior to the start of the presentation. Nanoelectronics combines physical principles of materials with the impressive capability of engineering ultra-small devices at the nanoscale. Magnetic field sensors—in particular, magnetoresistive (MR) sensors—were driven by the technological push from computers and information storage in the early 1990s. In this talk, Professor de Freitas will first introduce key concepts in spintronics and highlight the physical mechanisms defining sensor performance and the figures of merit for the classification of outstanding MR sensors. The impressive technological progress in thin film preparation and characterization, combined with nano- and microfabrication tools, offer a large spectrum for device design. The materials discussed include several varieties of thin films: oxide films as tunneling barriers, ultrathin amorphous and crystalline films, ultrathin textured layers with grain size control, magnetically soft layers, and antiferromagnetic films, all combined onto multilayer stacks, typically thinner than 60 nm in total. In addition, the noise mechanisms (the “killing factor” that limits MR sensor performance) will be discussed, and she will show successful strategies for improving the signal-to-noise ratio, which determines the ultimate field detectable by an MR sensor. Examples where spintronic sensors are useful tools for precision sensing will be provided, including integration with microfluidics, optical, and micro-electromechanical micromachined actuators. Detection principles, sensor design, simulations, and experimental validation will be discussed for exciting applications where MR sensors bring added value over competing technologies. She will show how challenging applications have inspired creative solutions, requiring joint skills in physics, materials, electronics, and mechanical engineering. Pr. de Freitas hopes that academics and engineers will be encouraged to propagate their expertise in magnetism to the young, talented people we see every day, and so promote innovation in future spintronic sensors.
