Power/Performance Bits: Dec. 23
By Ann Mutschler - 23 Dec, 2014 - Comments: 0

Glimpsing pathway of sunlight to electricity According to University of Oregon and Lund University researchers, four pulses of laser light on nanoparticle photocells in a University of Oregon spectroscopy experiment have opened a window on how captured sunlight can be converted into electricity. The work, which the researchers expect could inspire devices with improved efficiency in solar e... » read more

Is The Stacked Die Ecosystem Stagnating?
By Ann Mutschler - 18 Dec, 2014 - Comments: 2

It is now widely agreed that not much has been happening in terms of adoption for 2.5D interposer and 3D ICs. “It seems like everyone is still at the starting line waiting for the race to begin," said Javier DeLaCruz, senior director of engineering of [getentity id="22242" e_name="eSilicon"]. "Interposer assembly and IP availability for effectively using the [getkc id="82" comment="2.5D IC... » read more

Measuring electrons in silicon In what is believed to be a first, a team of physicists and chemists based at UC Berkeley, Ludwig-Maximilians Universität in Munich, Germany, the University of Tsukuba, Japan, and the Molecular Foundry at the Department of Energy’s Lawrence Berkeley National Laboratory has captured images of electrons breaking free of their atomic shells using attosecond pulse... » read more

High rise chip For decades, the mantra of the semiconductor industry has been ‘smaller, faster, cheaper.’ Stanford researchers are also adding ‘taller’ to the mix, and describing how to build high-rise chips that promise to leapfrog the performance of the single-story logic and memory chips on today's circuit cards. Stanford researchers said their approach would end the ‘logjams�... » read more

Yield Ramp Challenges Increase
By Ann Mutschler - 11 Dec, 2014 - Comments: 0

As semiconductor manufacturing moves down to smaller process nodes, there’s no doubt that it is increasingly difficult to ramp both test and manufacturing yields. One reason for this is simply scale. Smaller nodes translate into more steps and greater complexity in the manufacturing process, with attendant process variations. “Smaller process nodes increase the amount of embedded mem... » read more

Personal Security In The IoT
By Ann Mutschler - 09 Dec, 2014 - Comments: 0

I have to admit that in some regards, the Internet of Things concerns me…and not necessarily in a good way. Yes, I appreciate how convenient it will be when my refrigerator automatically orders my groceries when I get low on something, manages the electricity usage in my home, not to mention monitoring all of my bodily functions (ok, that might be an exaggeration), but are we stopping to ask ... » read more

Path to quantum transistors An odd, iridescent material that's puzzled physicists for decades turns out to be an exotic state of matter that could open a new path to quantum computers and other next-generation electronics, according to University of Michigan physicists. The researchers have been able to confirm that several properties of the compound samarium hexaboride that raise hopes for... » read more

Light in lieu of wires In a development that could eventually lead to computers that use optics rather than electricity to carry data, Stanford engineers have designed and built a prism-like device they call an ‘optical link’ that can split a beam of light into different colors and bend the light at right angles. The optical link is a tiny slice of silicon etched with a pattern that res... » read more

Cost Reduction, Power Management Get More Intense In IoT
By Ann Mutschler - 04 Dec, 2014 - Comments: 0

Power has become a consideration even if there is a plug in the wall. But for applications sitting out who knows where in the [getkc id="76" comment="Internet of Things"] (IoT), it is more than a consideration. It is one of the primary requirements, given the small size of these devices, rivaled only by cost. Reflecting on what brought the industry to this point, Aveek Sarkar, vice president... » read more

Architecting For Optimal Interface IP Integration
By Ann Mutschler - 04 Dec, 2014 - Comments: 0

Semiconductor Engineering sat down to discuss the design and integration of complex interface IP with Ty Garibay, VP of engineering at Altera; Brian Daellenbach, president of Northwest Logic; Frank Ferro, senior director of product management for memory and interface IP at Rambus; Saman Sadr, director of analog design at Semtech; and Navraj Nandra, senior director of marketing for analog/mixed ... » read more
