Capacitors in interposers Scientists at Tokyo Institute of Technology developed a 3D functional interposer containing an embedded capacitor. They tout the design as saving package area and reducing wiring length, resulting in less noise and power consumption. The capacitive elements are embedded inside a 300mm silicon piece using permanent adhesive and mold resin. The interconnects between ... » read more

Amplifying light for lidar Engineers at University of Texas at Austin and University of Virginia developed a light detector that can amplify weak light signals and reduce noise to improve the accuracy of lidar. "Autonomous vehicles send out laser signals that bounce off objects to tell you how far away you are. Not much light comes back, so if your detector is putting out more noise than th... » read more

Shrinking RFID chips Researchers at North Carolina State University built a new, tiny RFID chip. They expect the chip to help drive down costs for RFID tags, making it possible to embed them in more things for supply chain security. "As far as we can tell, it's the world's smallest Gen2-compatible RFID chip," said Paul Franzon, Professor of Electrical and Computer Engineering at NC State. I... » read more

Graphene PUFs Researchers at Pennsylvania State University propose using graphene to create physically unclonable functions (PUFs) that are energy efficient, scalable, and secure against AI attacks. The team first fabricated nearly 2,000 identical graphene transistors. Despite their structural similarity, the transistors' electrical conductivity varied due to the inherent randomness arising... » read more

Low-loss photonic IC Researchers at EPFL built a photonic integrated circuit with ultra-low loss. The team focused on silicon nitride (Si3N4), which has orders of magnitude lower optical loss compared to silicon. It is used in low-loss applications such as narrow-linewidth lasers, photonic delay lines, and nonlinear photonics. In applying the material to photonic ICs, they took advantage... » read more
