Power/Performance Bits: Jan. 31
By Jesse Allen - 31 Jan, 2017 - Comments: 0

Microbial nanowires Microbiologists at the University of Massachusetts Amherst report that they have discovered a new type of microbial nanowire, the protein filaments that bacteria use to make electrical connections with other microbes or minerals. The team was motivated by the potential for improved "green" conducting materials for electronics. According to Derek Lovley, professor of... » read more

Printable circuits with silver nanowires Scientists at Duke University compared the conductivity of films made from different shapes of silver nanostructures and found that electrons move through films made of silver nanowires much easier than films made from other shapes, like nanospheres or microflakes. In fact, electrons flowed so easily through the nanowire films that they could function... » read more

Paper-based bacteria battery Researchers at Binghamton University, State University of New York have created a bacteria-powered battery on a single sheet of paper that can power disposable electronics. The manufacturing technique reduces fabrication time and cost, and the design could revolutionize the use of bio-batteries as a power source in remote, dangerous and resource-limited areas. ... » read more

BEOL Barricades Ahead
By David Fried - 15 Dec, 2016 - Comments: 0

Coventor recently assembled an expert panel at IEDM 2016, to discuss changes to BEOL process technology that would be needed to continue dimensional scaling to 7 nm and lower. Among the questions posed to panelists: What is BEOL? Where does it begin and end? Are there fundamental limits to interconnect processes? How much longer can we continue to use current interconnect processes and ... » read more

Building Faster Chips
By Ed Sperling - 21 Jul, 2016 - Comments: 5

By Ed Sperling and Jeff Dorsch An explosion in IoT sensor data, the onset of deep learning and AI, and the commercial rollout of augmented and virtual reality are driving a renewed interest in performance as the key metric for semiconductor design. Throughout the past decade in which mobility/smartphone dominated chip design, power replaced performance as the top driver. Processors ha... » read more

Detecting anapoles A*STAR has detected invisible particles. Researchers from the Singaporean R&D organization have observed a new optical effect in nanoscale disks of silicon, which are patterns of radiation that do not scatter light. One example of a non-radiating source is called an anapole. An anapole, according to A*Star, is a distribution of charges and currents. They do not radiate wi... » read more

Atomic storage In the search for ever-smaller storage, a team of scientists at Delft University in the Netherlands built a 1 kilobyte memory where each bit is represented by the position of one single chlorine atom. "In theory, this storage density would allow all books ever created by humans to be written on a single post stamp," said lead scientist Sander Otte. They reached a storage de... » read more

Power/Performance Bits: May 3

Nanowire batteries University of California, Irvine researchers invented a nanowire-based battery material that can be recharged hundreds of thousands of times. Nanowires have long been sought as a battery material. However, these filaments are extremely fragile and don't hold up well to repeated discharging and recharging, or cycling. In a typical lithium-ion battery, they expand and gro... » read more

Will 5nm Happen?
By Mark LaPedus - 20 Jan, 2016 - Comments: 7

Chipmakers are ramping up their 16/14nm finFET processes, with 10nm finFETs expected to ship sometime in late 2016 or early 2017. So what’s next? The foundries can see a path to extend the finFET transistor to 7nm, but the next node, 5nm, is far from certain and may never happen. Indeed, there are several technical and economic challenges at 5nm. And even if 5nm happens, only a few compani... » read more

How Long Will FinFETs Last?
By Ann Mutschler - 13 Aug, 2015 - Comments: 0

Semiconductor Engineering sat down to discuss how long FinFETs will last and where we will we go next with Vassilios Gerousis, Distinguished Engineer at [getentity id="22032" e_name="Cadence"]; Juan Rey, Sr. Director of Engineering for Calibre R&D at [getentity id="22017" e_name="Mentor Graphics"]; Kelvin Low, Senior Director Foundry Marketing at [getentity id="22865" e_name="Samsung"]; and Vic... » read more
