A phase-locked loop (PLL) is the best way to generate the high frequencies—around 60 GHz—required for tomorrow’s 5G telecommunications and Wi-Fi. However, the higher the frequency, the lower the spectral quality—and transmission speeds. PhD candidate Clément Jany (who has since obtained a research position at Leti) set out to overcome this hurdle. And his solution […] >>

  MINATEC celebrates science The 2015 MINATEC “Parvis des Sciences” Science Fair and fifth annual EXPERIMENTA Art, Science, and Technology Fair will be held on the MINATEC campus from October 8–10, with plenty of science-related activities for everyone, from hardcore science enthusiasts to the general public. MINATEC held its first “Parvis des Sciences” in 2007, […] >>

Sorin Cristoloveanu, a research scientist at IMEP-LAHC, is organizing the sixth annual Nano-KISS* summer school from July 13–15 in Daejon, Korea. The program will host 120 participants and leading speakers from around the world, for a full program of talks on microelectronics, nanoelectronics, and sensors. Cristoloveanu, who spearheaded the Migas summer school, took the helm […] >>

A team of researchers from Leti, INAC, and ESRF combined X-ray tomography and Laue microdiffraction to determine the crystallographic orientation of micrometric grains. The technique, used in this case on 80-micron-thick copper vias, also indicates the area of deformation in the silicon matrix that surrounds the vias. Laue microdiffraction is very effective on thin films, […] >>

The Nanocharacterization Platform’s heating cell can be used to measure the properties of materials between –80°C and 600°C under controlled atmospheres. And, when coupled with ellipsometers, the thickness and the optical index of thin films can also be measured. Alternatively, Raman spectrometers can be added to study materials’ crystalline properties. Temperature measurements are particularly useful […] >>
