Low-k dielectric for future chips expands in place to fill gaps

Researchers at Leuven University and Belgian research lab Imec have developed a form-in-place low-k dielectric for insulating on-chip interconnect. The technique uses nano-porous metal-organic frameworks. “We’re using metal-organic frameworks as the insulating substance. These are materials that consist of metal ions and organic molecules. Together, they form a crystal that is porous yet sturdy,” said ...

Red LED streetlights make UK road bat-friendly

Worcestershire County Council has used red LED streetlights to install what it claims is the UK’s first bat-friendly highway – a ~60m stretch of the A4440 near to Warndon Wood nature reserve. “Research shows some species of bat are light shy and will not cross roads lit by white lights, which can stop them accessing ...

Huber Suhner unveils copper-less link to the antenna

Direct GPS-over-fiber (GPSoF) from Huber Suhner allows a fiber optic connection to be made directly onto an antenna eliminating the need for a separate power line. This capability means power constraints in remote antenna applications landscape can be addressed at the remote end. Huber Suhner expects this capability to provide significant benefits to installations within ...
