Week In Review: Auto, Security, Pervasive Computing


Automotive, mobility U.S. National Highway Traffic Safety Administration (NHTSA) release its first crash reports from ADAS (advanced driver assistance systems, i.e., SAE Level 2) and ADS (automated driving systems, i.e., SAE Levels 3-5).  The systems had to be in use at least 30 seconds before the crash in order for it to be reportable. The car may have had the system turned off at the time ... » read more

Ways To Address The Materials Crunch


Stellar growth over the last two years and the seemingly insatiable demand for chips, at least through 2025, is sparking massive investment by chip firms — as much as $500B over the next five years. But without significant boosts in raw materials, parts for tools, and silicon to fuel facilities, such numbers are unlikely to be met. Materials are the Achilles heel to the rapidly expanding c... » read more

Variation Making Trouble In Advanced Packages


Variation is becoming increasingly problematic as chip designs become more heterogeneous and targeted by application, making it difficult to identify the root cause of problems or predict what can go wrong and when. Concerns about variation traditionally have been confined to the most advanced nodes, where transistor density is highest and where manufacturing processes are still being fine-t... » read more

Chipmaking In The Third Dimension


Every few months, new and improved electronics are introduced. They’re typically smaller, smarter, faster, have more bandwidth, are more power-efficient, etc. — all thanks to a new generation of advanced chips and processors. Our digital society has come to expect this steady drip of new devices as sure as the sun will rise tomorrow. Behind the scenes, however, engineers are working feve... » read more

Quantum Computers And CMOS Semiconductors: A Review And Future Predictions


With the advent of quantum computing, the need for peripheral fault-tolerant logic control circuitry has reached new heights. In classical computation, the unit of information is a “1” or “0”. In quantum computers, the unit of information is a qubit which can be characterized as a “0”, “1”, or a superposition of both values (known as a “superimposed state”). The control c... » read more

Ultra-Low Resonance Frequency MEMS Gravimeter With Off-Resonance Closed-Loop Control


This paper reports on a MEMS gravimeter that has a closed-loop system to maintain an ultra-low resonance frequency of 1Hz. The low resonance frequency is attained by using a spring that is the resultant of positive mechanical stiffnesses and negative electrical stiffnesses. Voltage-tunability of the electrical stiffness enables ultra-small and tunable total stiffness. To attain a quick response... » read more

Blog Review: June 15


Ansys' Vidyu Challa considers common primary, or single-use, battery chemistries and how they affect that many important cell properties, such as energy density, flammability and safety, available cell constructions, temperature range, and shelf life. Synopsys' Rimpy Chugh and Rohit Kumar Ohlayan discuss some of the challenges arising from static linting of code, shifting linting left in the... » read more

Blog Review: May 25


Coventor's Michael Hargrove points to the need for a new generation of deep-submicron CMOS circuits that can operate at deep-cryogenic temperatures to achieve a quantum integrated circuit where the array of qubits is integrated on the same chip as the CMOS electronics required to read the state of the qubits. Ansys' Marc Swinnen warns about dynamic voltage drop as ultra-low supply voltages, ... » read more

Shortages Spark Novel Component Lifecycle Solutions


The semiconductor industry’s supply chain problems are prompting some innovative solutions and workarounds, and while they don't solve all problems, they are improving efficiency and extending equipment lifetimes. The shortages, which affect everything from the chips used in automotive, IoT, and consumer ICs to the equipment used to manufacture and test them — span global supply lines. T... » read more

There Is Plenty Of Room At The Top: Imagining Miniaturized Electro-Mechanical Switches In Low-Power Computing Applications


The first computers were built using electro-mechanical components, unlike today’s modern electronic systems. Alan Turing’s cryptanalysis multiplier and Konrad Zuse’s Z2 were invented and built in the first half of the 20th century, and were among the first computers ever constructed. Electro-mechanical switches and relays performed logic operations in these machines. Even after computers... » read more
