Test and Diagnosis Challenges for High-Yield Manufacturing in the Ångström Era

Plenary Session Summary:

As semiconductor technology advances into the Ångström era, the complexity of integrated circuits and manufacturing processes has reached unprecedented levels. This evolution introduces significant challenges for test, diagnosis, and failure analysis, where traditional approaches struggle to keep pace with shrinking geometries, increasing device variability, and heightened defect sensitivity. Ensuring diagnostic accuracy, identifying systematic issues, and minimizing test time is no longer just a technical objective; it is a strategic imperative for yield improvement and overall fab competitiveness.

This talk will examine the critical obstacles in test and diagnosis for advanced nodes, including the impact of ultra-scaled features on fault isolation, the limitations of conventional methodologies, and the growing need for adaptive, data-driven strategies. We will showcase innovative solutions that leverage machine learning, real-time analytics, and design-for-test enhancements to improve diagnostic quality, accelerate root-cause analysis, and enable faster corrective actions. These advancements contribute to higher yield, reduced cost, and quicker time-to-market. Special emphasis will be placed on the challenges of analyzing large-scale diagnostic data to uncover systematic defects early, enabling proactive process improvements, design corrections, and preventing costly excursions.

Attendees will gain insights into how leading-edge fabs are redefining test and diagnosis strategies to achieve uncompromising precision, accelerate time-to-yield, and maintain competitiveness in today’s most advanced manufacturing environments.

Low Power Challenges in IoT and IoE

Plenary Session Summary:

The increasing number of devices connected to the internet is providing the concept of Internet of Things, that together with Internet of Health, Internet of People and Internet of Something is constructing the Internet of Everything (IoE). There is also an overlapping between IoT and CPS (Cyber Physical Systems) that have as components not only electronic ones, but also mechanical components, optical components, organic components, chemical components, etc. A keyword in IoT is optimization, mainly power optimization. Power optimization must be done in all levels of design abstraction, and at physical level is related to the number of transistors. Also, many systems are critical ones, like in Internet of Heath, where reliability is a major issue. Most of the circuits designed nowadays use much more transistors than it is needed. The increasing leakage power and routing issues are an important reason to optimize the number of transistors, as leakage power is related to the number of transistors. Also, the replacement of a set of basic gates by a complex gate reduces the number of connections to be implemented using metal layers as well the number of vias. The reduction of the number of connections to be implemented using metal layers helps to improve routing and also helps to improve reliability. To cope with this goal, it is needed to provide tools to automatically generate the layout of any transistor network.

Embodied AI for Next Generation Intelligent Systems

Plenary Session Summary:

Embodied AI represents a major evolution in intelligent systems by tightly coupling perception, cognition, and action within physical or cyber-physical platforms. Moving beyond disembodied, prompt-driven models, embodied intelligent systems integrate sensing, reasoning, and decision-making to autonomously interact with and adapt to dynamic environments. These systems decompose high-level objectives into actionable plans, coordinate perception and control loops, and execute tasks through continuous feedback from sensors, actuators, and external digital resources. Such goal-directed behavior enables intelligent agents to operate reliably under real-world constraints, including latency, energy efficiency, and uncertainty. This paradigm shift supports the development of autonomous and collaborative systems capable of managing complex tasks, learning from interaction, and adjusting strategies in real time. In healthcare-oriented intelligent systems, embodied AI enables diagnostic and decision-support platforms that fuse multimodal sensor data, patient context, and clinical knowledge to assist practitioners. Wearable and embedded sensing devices further support personalized and adaptive care by enabling continuous monitoring and closed-loop adjustment of treatment strategies. By unifying embedded intelligence, real-time inference, and system-level integration, embodied AI paves the way for scalable, efficient, and trustworthy intelligent systems operating at the edge.

Embedded Systems application in systemic approach with societal issues

Plenary Session Summary:

Modern technological systems are becoming increasingly complex, interconnected, and deeply embedded in social, economic, environmental, and organizational contexts. From artificial intelligence and digital transformation to smart cities, healthcare, Industry 5.0, and sustainable manufacturing, technological innovation can no longer be considered independently from the human and societal environment in which it operates. This evolution calls for a systemic approach capable of understanding the interactions, dependencies, and feedback mechanisms that shape complex systems.

This talk will examine the fundamental distinction between system design and systems thinking. While system design focuses primarily on components, architectures, functions, and processes, systems thinking considers the system as an integrated whole, emphasizing the interdependencies among technologies, humans, organizations, infrastructures, policies, economic factors, and the environment. This perspective helps explain not only how systems operate, but also how local decisions can produce global and sometimes unexpected consequences.

Particular attention will be given to socio-technical systems, where technological performance is closely connected to human behaviour, organizational structures, ethical considerations, societal expectations, and environmental constraints. Examples from artificial intelligence, cybersecurity, digital healthcare, Industry 4.0 and Industry 5.0, embedded systems, blockchain, and sustainable digital infrastructures will illustrate both the opportunities and risks associated with technological innovation.

The talk will address major societal challenges including trust, transparency, privacy, cybersecurity, digital inclusion, algorithmic bias, human autonomy, environmental impact, energy consumption, and responsible innovation. These challenges demonstrate that optimizing an individual technical component does not necessarily result in an optimal overall system. Technically efficient solutions may generate unintended organizational, economic, environmental, or societal consequences.

A systemic approach therefore requires multidisciplinary analysis throughout the entire system life cycle, from requirements and architecture to implementation, deployment, operation, adaptation, and decommissioning. It enables stakeholders to identify interdependencies, anticipate unintended consequences, evaluate trade-offs, and design systems that are sustainable, resilient, secure, responsible, and socially acceptable.

Special emphasis will be placed on Industry 5.0 and human-centric digital societies, where technology is expected to contribute not only to productivity and performance but also to human well-being, environmental sustainability, resilience, inclusiveness, and societal value. Engineers and technology leaders must therefore consider not only what can technically be achieved, but also why it should be implemented, for whom it creates value, what risks it introduces, and what long-term consequences it may have.

The talk will conclude by highlighting the importance of integrating systems thinking into modern engineering education, research, and industrial practice. Engineers must combine technical expertise with interdisciplinary reasoning, critical thinking, ethical awareness, and an understanding of human and societal dynamics.

Ultimately, the challenge is not simply to build more powerful and efficient technologies, but to design and govern systems that are sustainable, secure, resilient, inclusive, human-centred, and beneficial to society as a whole.
