The Michelangelo step: removing scalloping and tapering effects in high aspect ratio through silicon vias

Edoardo Charbon, Sandro Carrara, Simone Frasca, Rebecca Camilla Leghziel

We present here, for the first time, a fabrication technique that allows manufacturing scallop free, non-tapered, high aspect ratio in through-silicon vias (TSVs) on silicon wafers. TSVs are among major technology players in modern high-volume manufacturin ...

In-situ strength of individual silicon particles within an aluminium casting alloy

Andreas Mortensen, Goran Zagar, Martin Guillermo Mueller

Measurements of local strength are performed in-situ on individual silicon particles that constitute the second phase of aluminium alloy A356. Particles are shaped using Focused Ion Beam (FIB) milling such that, upon the application of a compressive force ...

The Gaia-ESO Survey: properties of newly discovered Li-rich giants

Carmela Lardo

Aims. We report 20 new lithium-rich giants discovered within the Gaia-ESO Survey, including the first Li-rich giant with an evolutionary stage confirmed by CoRoT (Convection, Rotation and planetary Transits) data. We present a detailed overview of the prop ...

Characterisation and hydration of ye'elimite containing cements

Frank Bullerjahn

Calcium sulphoaluminate cements (CSA) with the main phase yeâelimite are a promising class of non-Portland cements which are gaining increasing interest from the cement industry. However, the hydration kinetics of CSA cements varies strongly, even for ce ...

Strength and fracture of silicon second-phase particles in aluminium casting alloys

Martin Guillermo Mueller

The mechanical behaviour of metallic materials that have a microstructure composed of a brittle phase embedded in a ductile matrix is dictated by a complex interplay of factors such as local phase properties, cohesive properties, geometrical characteristic ...

Silicon particle pinhole defects in aluminium–silicon alloys

Andreas Mortensen, Martin Guillermo Mueller, Marta Fornabaio

It was recently shown that silicon particles in heat-treated Al–Si casting alloys can contain flaws such as surface pinholes and grooves, which cause varying degrees of reduction in the in situ particle fracture strength and hence influence the mechanical ...

Through Silicon Vias With Invar Metal Conductor for High-Temperature Applications

Mikhail Asiatici, Göran Stemme

Through silicon vias (TSVs) are key enablers of 3-D integration technologies which, by vertically stacking and interconnecting multiple chips, achieve higher performances, lower power, and a smaller footprint. Copper is the most commonly used conductor to ...

Characterization of Surface State of Inert Particles: Case of Si and SiC

Hubert Girault, Fernando Cortes Salazar, Véronique Amstutz, Desire Martial Koutouan Abro

Silicon and Silicon carbide particles have been investigated by the mean of infrared (IR) spectroscopy and X-ray photoelectron spectroscopy (XPS) to establish their surface states. The results of this research are based on the estimation of the area under ...

Microscopic strength of silicon particles in an aluminium–silicon alloy

Andreas Mortensen, Goran Zagar, Martin Guillermo Mueller, Marta Fornabaio

A microscopic three-point bending test that measures the strength of faceted particles of high aspect ratio is developed and used to probe individual coarsened plate-like silicon particles extracted from the eutectic Al-12.6%Si alloy. Focused ion beam mill ...

Flexural strength of micron-scale plate-like silicon in aluminum

Andreas Mortensen, Goran Zagar, Martin Guillermo Mueller, Marta Fornabaio

Mechanical properties of composite materials and alloys are strongly influenced by the intrinsic mechanical properties of the reinforcing phases they contain; however, due to the irregular shape and small size of particulate reinforcements, measuring their ...
