“…An example of metrology for materials was provided from the Communications Technology Laboratory (CTL), where she served as the operating unit director before becoming the CHIPS R&D Metrology Program directorspecifically standard reference materials (SRMs) for 5G materials. As an example of the ability of metrology to enhance the security and provenance of microelectronic-based components and products, the NIST SP1278 document, which she co-authored, was highlighted [12].…”

This is the report of a hybrid working group meeting held on April 25, 2023, at the National Institute of Standards and Technology (NIST) in Boulder, CO. The working group was focused on extreme ultraviolet lithography (EUVL) research, development, and manufacturing. The meeting allowed for productive discussions on many technical aspects of EUVL. Industry participants gave presentations that helped inform this report's outline of the current state of the science, challenges, needs, and future opportunities for accelerated innovation in EUVL. The report also includes information on some of NIST's efforts that could begin or continue to support the USA semiconductor industry. Cohesively presenting some of NIST's research and capabilities at the working group meeting provided external stakeholders visibility and the opportunity to comment. The meeting was insightful for industry participants learning about NIST's research capabilities .In turn, NIST researchers gained a deeper understanding of the industry's needs to identify where NIST's metrology expertise could assist in EUVL research. The meeting and this report do not, and are not intended to, capture the entire perspective of the EUVL industry but rather serve as a discussion starting point. Future work includes expanding participation, honing NIST research sub-groups to specific needs of EUVL, and executing priority research discussed in the working group meeting or any future meetings. Through engagement with the USA EUVL industry, targeted research collaborations are hoped to be created, accelerating semiconductor manufacturing innovation and generating meaningful value for USA taxpayers.

“…Counterfeit devices generally have unknown quality and long-term reliability and are thus less trustworthy. Counterfeit devices affect many industrial sectors, including computers, communications, automotive electronics and military systems; the consequences of system failure due to low-quality components can impact safety, reliability of infrastructure and national security (Booth et al, 2022).…”

Purpose This paper aims to discuss the ethical aspects of hardware reverse engineering (HRE) and propose an ethical framework for HRE when used to mitigate cyber risks of the digital supply chain of critical infrastructure operators. Design/methodology/approach A thorough review and analysis of existing relevant literature was performed to establish the current state of knowledge in the field. Ethical frameworks proposed for other areas/disciplines and identified pertinent ethical principles have been used to inform the proposed framework’s development. Findings The proposed framework provides actionable guidance to security professionals engaged with such activities to support them in assessing whether an HRE project conforms to ethical principles. Recommendations on action needed to complement the framework are also proposed. According to the proposed framework, reverse engineering is neither unethical nor illegal if performed honourably. Collaboration with vendors and suppliers at an industry-wide level is critical for appropriately endorsing the proposed framework. Originality/value To the best of the authors’ knowledge, no ethical framework currently guides cybersecurity research, far less of cybersecurity vulnerability research and reverse engineering.

“…An important application of flexible materials at microwave frequencies is in the design of electromagnetic absorbers, [22][23][24][25][26][27] which have applications in electromagnetic interference, [28][29][30][31][32][33][34][35] antenna design, [36] IoT, [37] automotive radar, and for potential mitigation of eavesdropping via electromagnetic sidechannels, [38][39][40] with important consequences for hardware security assurance. [41] The electromagnetic absorbance of flexible materials can be engineered by varying composition to obtain desired performance and add increased functionality while minimizing deleterious effects such as loss and dispersion. Selfbiased materials such as barium hexaferrite offer the opportunity for tailoring absorption at specific frequencies, without the need for external magnetic field bias.…”

Flexible and stretchable materials have attracted significant interest in wearable electronics and bioengineering fields. Recent developments also incorporate embedded microwave circuits and systems with engineered flexible materials that operate over a broad frequency range (≈1–100 GHz). Herein, a simple flip‐chip technique is used to evaluate frequency‐dependent electromagnetic properties of flexible materials and applied to evaluate engineered microwave absorbers based on self‐biased barium hexaferrite composites. On‐wafer error correction and de‐embedding techniques are applied to determine broadband electromagnetic properties of the material‐loaded transmission lines by placing the materials on top of coplanar waveguide transmission lines. Finite‐element simulations along with broadband measurements were employed to estimate the electromagnetic material properties. To demonstrate, flexible polydimethylsiloxane (PDMS) composites are fabricated with barium hexaferrite nanoparticles and complex permittivity and permeability of the composites are quantified under zero magnetic field bias up to 110 GHz. Frequency‐dependent composite permeability is fitted to models describing the ferromagnetic resonance of the self‐biased barium hexaferrite nanoparticles in polydimethylsiloxane, and constituent nanoparticle properties are estimated using the Maxwell–Garnett mixing model. This study paves the way to exploit a wide range of engineered materials in flexible, wearable, and biomedical electronics applications and presents a convenient methodology to extract important broadband electromagnetic properties of nanoparticles for customized electromagnetic applications.
