Energy Harvesting Starting To Gain Traction


Tens of billions of IoT devices are powered by batteries today. Depending on the compute intensity and the battery chemistry, these devices can run steadily for short periods of time, or they can run occasionally for decades. But in some cases, they also can either harvest energy themselves, or tap into externally harvested energy, allowing them to work almost indefinitely. Energy harvesting... » read more

Always-On, Ultra-Low-Power Design Gains Traction


A surge of electronic devices powered by batteries, combined with ever-increasing demand for more features, intelligence, and performance, is putting a premium on chip designs that require much lower power. This is especially true for always-on circuits, which are being added into AR/VR, automotive applications with over-the-air updates, security cameras, drones, and robotics. Also known as ... » read more

Architecting Faster Computers


To create faster computers, the industry must take a major step back and re-examine choices that were made half a century ago. One of the most likely approaches involves dropping demands for determinism, and this is being attempted in several different forms. Since the establishment of the von Neumann architecture for computers, small, incremental improvements have been made to architectures... » read more

Increasing Performance With Data Acceleration


Increasing demand for functions that require a relatively high level of acceleration per unit of data is providing a foothold for in-line accelerator cards, which could mean new opportunities for some vendors and a potential threat for others. For years, either CPUs, or CPUs with FPGA accelerators, met most market needs. But the rapid increase in the volume of data everywhere, coupled with t... » read more

Strategies For Faster Yield Ramps On 5nm Chips


Leading chipmakers TSMC and Samsung are producing 5nm devices in high volume production and TSMC is forging ahead with plans for first 3nm silicon by year end. But to meet such aggressive targets, engineers must identify defects and ramp yield faster than before. Getting a handle on EUV stochastic defects — non-repeating patterning defects such as microbridges, broken lines, or missing con... » read more

Finding And Applying Domain Expertise In IC Analytics


Behind PowerPoint slides depicting the data inputs and outputs of a data analytics platform belies the complexity, effort, and expertise that improve fab yield. With the tsunami of data collected for semiconductor devices, fabs need engineers with domain expertise to effectively manage the data and to correctly learn from the data. Naively analyzing a data set can lead to an uninteresting an... » read more

Silicon Lifecycle Management’s Growing Impact On IC Reliability


Experts at the Table: Semiconductor Engineering sat down to talk about silicon lifecycle management, how it's expanding and changing, and where the problems are, with Prashant Goteti, principal engineer at Intel; Rob Aitken, R&D fellow at Arm; Zoe Conroy, principal hardware engineer at Cisco; Subhasish Mitra, professor of electrical engineering and computer science at Stanford University; a... » read more

New Challenges For Connected Vehicles


Connected vehicles are all about convenience and safety. Modern vehicles are connected to the Internet via wireless networks, consumer apps, and infotainment systems, and there is work underway to connect them over 5G to guided driving. But there also are challenges to making all of this work securely, safely, and as expected throughout the expected lifetimes of chips and systems. The goal i... » read more

Battery Management Getting Competitive For EVs


The success or failure of future electric vehicles will depend on where and how those cars are used, as well as significant advances in battery materials, energy density, and some very complex battery management systems. Battery power needs to be balanced, stored for extended times, and delivered to wherever it is needed most in real time. This is a huge challenge, and nearly everything in a... » read more

Electric Planes Taking Off


As the aeronautics industry and aviation startups design and test zero-emissions aircraft, they are solving problems beyond just adapting to fuel sources that cut greenhouse gas emissions. Problems of weight, noise, redundancy, refueling, cost, and turnaround time are being tackled one airline seat at time. Powerful tools can help aircraft designers look at the aircraft system as a whole, fe... » read more
