Dislocations create elastic fields, detectable by surface-sensitive techniques like EBSD and ECCI. In this report, a field dislocation mechanics (FDM) model to compare surface and bulk dislocation signatures in GaN layers on Si substrates is used. Significant differences between surface and bulk fields highlight potential misinterpretations in surface-based dislocation characterization. Metrics for accurate dislocation characterization and perform virtual ECCI are established.

Plastic deformation of Cu metallization in power devices results from a combination of heat and thermomechanical stress, mainly produced by the difference in CTE between the metal and the semiconductor and oxides. Using electron microscopy, we found that the deformation mechanisms implying dislocation activities explain a minor portion of the changes endured by the copper. It is therefore supposed that pore formation and cracks growth result from another mechanism, probably grain boundary accelerated diffusion.

A new in-situ set-up for thermal cycling of copper on silicon (polyheater) samples has been established at IKTS. An exemplary sample was imaged using X-ray transmission imaging, validating the set-up functionality. New sample layouts for 3D imaging were designed and produced at Infineon Technologies Austria and KAI, but could not yet be imaged due to production delays.

The AddMorePower project uses the repository/database NOMAD, developed by FAIRmat. It is a material science-oriented database, adhering to the FAIR principles that offers both public and private instances. The document explains the choice for this tool and the development that are needed to properly use this tool in the project.

D7.1 provides an initial plan for dissemination and exploitation incl. communication activities and training and will be periodically updated based on the project’s progress. It also constitutes an initial dissemination & communication kit for AddMorePower, as well as the launch of the project website and communication infrastructure in M03.

In this report the imaging protocols for lab-based Transmission X-ray Microscopy and nano-computed tomography technique (TXM/nano-CT) to study use case samples from WP6 at nanoscale is developed and described. The characterisation methodology based on applying several photon energies provided by two TXM/nano-CT tools to study polyheaters with certain geometry and cycling parameters.

D2.2 includes the systematic description and documentation of materials modelling and characterization data created in AddMorePower. To allow interoperability, AddMorePower uses the community standards CHADA and MODA.

The project quality plan (project handbook) constitutes a set of project templates and explains the project management, review, internal quality control process, and other organizational topics such as meeting organization. This handbook shall support all partners in their daily work.

The comprehensive Data Management Plan (DMP) outlines the type of collected data, produced research outputs, the compliance with the FAIR data principles, the way in which data will be stored and preserved throughout the lifespan of AddMorePower, ethical aspects and security issues. The DMP will be a living document which will be regularly updated.
