Weekly group seminars

During COVID-19 Pandemic, the group organized weekly scientific seminars held online. A group member presented his/her work, an idea, a paper or anything that might benefit from a group scientific discussion. Some guests joined us from time to time to present their research. 

Here is the calendar of past events held online during the lockdown:

Title: "X-ray based dimensional metrology for next generation nanoelectronics"

The microelectronics industry continues to shrink the size and increase the complexity of electronic devices as they follow Moore’s Law. Following the semiconductor technology roadmap to sub-10 nm devices presents tremendous challenges for both metrology and patterning technology. We will start by discussing the development of a small angle X-ray scattering (SAXS) method called critical-dimension (CD) SAXS for measuring the shape of 3D nanoscale devices such as gate-all around transistors, finFETs, and 3D NAND flash memory structures.1,2 The CDSAXS method is now being commercially developed and evaluated in fabs. We will then discuss new soft X-ray measurement methods being developed to characterize next generation lithographic technologies including block copolymer (BCP) directed self assembly (DSA) patterns and EUV photoresists. Soft X-rays allow resonant contrast based on chemical functional group. We will show how we can measure nm-scale changes in chemistry in organic nanostructures such as BCPs and photoresist. These measurements allow critical insights into the DSA and EUV exposure processes.

SEMINAR - Milorad Milosevic (Antwerp UNiv.)

Title: "Advances in multiscale simulations of superconducting devices"

While modern experimental techniques are enabling increasingly multifold studies of superconductivity (from in-situ synthesis to transport and scanning-probe measurements), the community has witnessed an increasing gap between the ab initio calculations and those on mean-field levels, and even more to the desired device modelling. At present, the only tool able to address the needed multi-scale modelling of superconductors, nanopatterned into electronic circuitry, are the advanced Ginzburg-Landau simulations. We have recently developed a multiscale approach where first information about fermiology, vibrational modes, and electron-phonon coupling are obtained from first principles for the materials of interest [1], to be subsequently translated into (anisotropic) superconducting properties, that can further serve to properly parametrize mean-field models to capture the behavior of that superconductor in applied magnetic field and electric current.

In this talk, I will review our recent further breakthroughs in that respects, and show realized numerical experimentation on circuits of arbitrary shape (on advanced size and time scale), variable thickness, inhomogeneous parameters, with self-consistent account for magnetic field distribution, the electric field generated under applied current, incorporated heating effects, thus fully characterized behavior of the superconducting condensate in non-equilibrium conditions that reveals physics behind improved or worsened performance of various realistic transport devices [2-4].

Special Issue


Seminar - Fernando Castro (NPL)

Prof Fernando Castro, Head of Materials Science & Engineering at the National Physical Laboratory, UK.

Title: "Multiscale characterisation for nanoelectronics"

This talk will provide a brief introduction to Materials Metrology at NPL and then focus on examples of multiscale characterisation for nanoelectronics. Novel optoelectronic devices make use of advanced nanomaterial systems, where the nanoscale composition and morphology significantly affects the performance. Despite advances in analytical characterisation methods, such structure-property relationship is very challenging to measure directly.

NPL has been developing a suite of characterisation techniques to measure these materials and devices in situ and with high spatial resolution.

We will cover examples where these methods are applied to solar cells, 2D materials and nanowire based electronics, from macroscopic measurements down to the nanoscale.
