Rubbery material for stretchable electronics Researchers at the University of Houston came up with a rubbery semiconducting material that they say could find applications in stretchable electronics, such as human-machine interfaces, implantable bioelectronics, and robotic skins. Cunjiang Yu, Bill D. Cook Assistant Professor of mechanical engineering at the University of Houston and correspo... » read more

EDA Grabs Bigger Slice Of Chip Market
By Brian Bailey - 31 Jan, 2019 - Comments: 0

EDA revenues have been a fairly constant percentage of semiconductor revenues, but that may change in 2019. With new customers creating demand, and some traditional customers shifting focus from advanced nodes, the various branches of the EDA tool industry may be where sticky technical problems are solved. IC manufacturing, packaging and development tools all are finding new ways to handle t... » read more

Interest Grows In Ferroelectric Devices
By Katherine Derbyshire - 27 Dec, 2018 - Comments: 0

Ferroelectric FETs and memories are beginning to show promise as researchers begin developing and testing next-generation transistors. One measure of the efficiency of a transistor is the subthreshold swing, which is the change in gate voltage needed to increase the drain current by one order of magnitude. Measured in units of millivolts per decade, in conventional MOSFETs it is limited to k... » read more

What’s A Mott FET?
By Katherine Derbyshire - 17 Dec, 2018 - Comments: 0

The unique physics of two-dimensional semiconductors offers the potential for new kinds of switches that could extend the usefulness of conventional MOSFETs into a variety of new areas. A MOSFET applies a voltage to one side of the gate capacitor. The resulting electric field in the channel shifts the band structure and facilitates or impedes the flow of carriers. So as devices shrink, the g... » read more

Deep learning device identifies airborne allergens To identify and measure airborne biological particles, or bioaerosols, that originate from living organisms such as plants or fungi, UCLA researchers have invented a portable device that uses holograms and machine learning. The device is trained to recognize five common allergens — pollen from Bermuda grass, oak, ragweed and spores from t... » read more

Ethics, regional differences for programming autonomous vehicles MIT researchers have revealed some distinct global preferences concerning the ethics of autonomous vehicles, as well as some regional variations in those preferences based on a recently completed survey. [caption id="attachment_24139620" align="alignleft" width="300"] Ethical questions involving autonomous vehicles are the foc... » read more

Week In Review: Design, Low Power
By Jesse Allen - 26 Oct, 2018 - Comments: 0

Tools OneSpin launched a formal verification tool that integrates with all major simulators, coverage databases and viewers, and chip design verification planning tools to provide a comprehensive view of verification progress. Comprised of two new formal apps, it can identify unreachable coverage points and provide them to the simulator to reduce wasted effort. Synopsys released the latest ... » read more

Solving the quantum verification problem UC Berkeley doctoral candidate Urmila Mahadev spent 8 years in graduate school solving one of the most basic questions in quantum computation, which is how to know whether a quantum computer has done anything quantum at all, according to Quanta Magazine. In her paper, Mahadev presents the first protocol allowing a classical computer to interactively ... » read more

RISC-V: More Than a Core
By Brian Bailey - 15 Oct, 2018 - Comments: 2

The open-source RISC-V instruction set architecture (ISA) is attracting a lot of attention across the semiconductor industry, but its long-term success will depend on levels of cooperation never seen before in the semiconductor industry. The big question now is how committed the industry is to RISC-V's success. The real value that RISC-V brings is the promise of an ecosystem and the opportun... » read more

RISC-V Inches Toward The Center
By Ann Mutschler - 01 Oct, 2018 - Comments: 1

RISC-V is pushing further into the mainstream, showing up across a wide swath of designs and garnering support from a long and still-growing list of chipmakers, tools vendors, universities and foundries. In most cases it is being used as a complementary processor than a replacement for something else, but that could change in the future. What makes RISC-V particularly attractive to chipmaker... » read more
