Embedded Microprocessor Extension Design and Optimization for Real-Time Edge Computing


Abstract "With the development of 5G communication technology, more and more applications could be integrated into one system. Edge computing system and mixed-criticality system may integrate tasks of different criticality levels, which brings better balance in isolation and performance. Such advantages make it gradually become a research hotspot in edge computing and real-time systems with ... » read more

Silicon Thermo-Optic Switches with Graphene Heaters Operating at Mid-Infrared Waveband


Abstract "The mid-infrared (MIR, 2–20 μm) waveband is of great interest for integrated photonics in many applications such as on-chip spectroscopic chemical sensing, and optical communication. Thermo-optic switches are essential to large-scale integrated photonic circuits at MIR wavebands. However, current technologies require a thick cladding layer, high driving voltages or may introduce h... » read more

Improving Machine Learning-Based Modeling of Semiconductor Devices by Data Self-Augmentation


Abstract: "In the electronics industry, introducing Machine Learning (ML)-based techniques can enhance Technology Computer-Aided Design (TCAD) methods. However, the performance of ML models is highly dependent on their training datasets. Particularly in the semiconductor industry, given the fact that the fabrication process of semiconductor devices is complicated and expensive, it is of grea... » read more

2D Semiconductors Make Progress, But Slowly


Researchers are looking at a variety of new materials at future nodes, but progress remains slow. In recent years, 2D semiconductors have emerged as a leading potential solution to the problem of channel control in highly scaled transistors. As devices shrink, the channel thickness should shrink proportionally. Otherwise, the gate capacitance won’t be large enough to control the flow of cu... » read more

Chasing After Carbon Nanotube FETs


Carbon nanotube transistors are finally making progress for potential use in advanced logic chips after nearly a quarter century in R&D. The question now is whether they will move out of the lab and into the fab. Several government agencies, companies, foundries, and universities over the years have been developing, and are now making advancements with carbon nanotube field-effect transi... » read more

Power/Performance Bits: June 16


One-directional optical Researchers from University of Pennsylvania, Peking University and Massachusetts Institute of Technology developed a design for optical devices that radiate light in only one direction, which could reduce energy consumption in optical fiber networks and data centers. Light tends to flow in a single direction optical fibers, but while most of the light passing through... » read more

Power/Performance Bits: May 26


Warmer quantum computing Researchers at the University of New South Wales Sydney, Université de Sherbrooke, Aalto University, and Keio University developed a proof-of-concept quantum processor unit cell on a silicon chip that works at 1.5 Kelvin – 15 times warmer than current chip-based technology that uses superconducting qubits. "This is still very cold, but is a temperature that can b... » read more

Possible Uses Narrow For Negative Capacitance FETs


The discovery of a ferroelectric phase in hafnium dioxide (HfO2) has sparked significant interest in opportunities for integration of ferroelectric transistors and memories with conventional CMOS devices. Demonstrations of “negative capacitance” behavior in particular suggest these devices might evade the 60 mV/decade limit on subthreshold swing, thereby improving transistor efficiency. ... » read more
