A new scanning microscope developed at Brown University can uncover defects in the smallest and most complex integrated circuits at a resolution 1,000 times greater than current technology. The scanner removes a barrier to further shrinking of integrated circuits: As circuits get smaller, non-visual defects become harder to find.
Micro mouse bite
A current-density image, taken with a Circuit Scan 1000 high-resolution magnetic microscope, reveals a tiny flaw in one of two 0.25-micron metal wires in an integrated circuit chip. Further magnification (detail) shows the right-hand wire has a “mouse bite” along one of its edges, where the electrical current shows up as a tiny hot spot
“This microscope will allow manufacturers to find defects in each embedded wire in ever-tinier circuits,” said Brown University professor Gang Xiao. He developed the instrument’s hardware and software with Ben Schrag, who will receive his Ph.D. at Brown this month.
The microscope’s magnetic-scanning technology suggests a new small, non-invasive form of remote detection, said the researchers, who envision a “pass-over and detect” magnetic-sensor-tipped pen, for use in finding internal cracks within aircraft, sensing biological agents in the environment or body, or recognizing counterfeit bills or other objects.

Combining infrared radiation and air management to reduce energy use
19.02.2019 | Heraeus Noblelight GmbH
Up to now, OLEDs have been used exclusively as a novel lighting technology for use in luminaires and lamps. However, flexible organic technology can offer much more: as an active lighting surface, it can be combined with a wide variety of materials, not just to modify but to revolutionize the functionality and design of countless existing products. To exemplify this, the Fraunhofer FEP together with the company EMDE development of light GmbH will be presenting hybrid flexible OLEDs integrated into textile designs within the EU-funded project PI-SCALE for the first time at LOPEC (March 19-21, 2019 in Munich, Germany) as examples of some of the many possible applications.
The Fraunhofer FEP, a provider of research and development services in the field of organic electronics, has long been involved in the development of...
For the first time, an international team of scientists based in Regensburg, Germany, has recorded the orbitals of single molecules in different charge states in a novel type of microscopy. The research findings are published under the title “Mapping orbital changes upon electron transfer with tunneling microscopy on insulators” in the prestigious journal “Nature”.
The building blocks of matter surrounding us are atoms and molecules. The properties of that matter, however, are often not set by these building blocks...
