We present a 7nm technology with the tightest contacted poly pitch (CPP) of 44/48nm and metallization 36nm ever reported in FinFET technology. To overcome optical lithography limits, Extreme Ultraviolet Lithography (EUV) has been introduced for multiple critical levels first time. Dual strained channels have also implemented to enhance mobility high performance applications.
Two high-accuracy goniometers equipped with two bent silicon crystals were installed in the betatron cleaning insertion of CERN Large Hadron Collider (LHC) during its long shutdown. First beam tests recently performed at LHC 450 GeV/c and 6500 stored proton beams to investigate feasibility halo collimation assisted by crystals. For first time channeling protons was observed a particle accelerator. A strong reduction losses due nuclear inelastic interactions aligned crystal comparison...
The T2K experiment studies oscillations of an off-axis muon neutrino beam between the J-PARC accelerator complex and Super-Kamiokande detector. Special emphasis is placed on measuring mixing angle theta_13 by observing electron appearance via sub-dominant to oscillation, searching for CP violation in lepton sector. includes a sophisticated, off-axis, near detector, ND280, situated 280 m downstream production target order measure properties understand better interactions at energy scale below...

Middle-of-the-line (MOL) interconnect and contact resistances represent significant impacts to high-end IC performance at ≤ 10 nm nodes. CVD W-based metallization has been used for all nodes since the inception of damascene. However, it is now being severely challenged due limited scaling traditional PVD Ti/CVD TiN barrier ALD nucleation layers.

Abstract Introduction In animal models, refined carbohydrates (RF) worsen Alzheimer's disease (AD). However, the long‐term effects of high RF intake on risk dementia and AD are poorly described in epidemiological studies. Moreover, interaction between apolipoprotein E ε4 allele ( APOE ‐ε4) is unknown. Our study investigated whether RF‐rich diets associated with AD. Methods The glycemic load (GL) was quantified 2777 elderly participants from French Three‐City Study to estimate intake. Then,...
A charged particle telescope has been constructed for data taking at high rates in a CERN 400 GeV/c proton beam line.
