The research activities are centered around the general topic "Electrical, electronical and electro-optical material systems". The Materials Physics Division consists out of three sections, in which the activities are organised : ECR (Electrical Characterisation and Reliability); PCC (Physicochemical Characterisation) and TFD (Thin Films and Devices) In the ECR section, the activities are situated in the field of quality and reliability in the field of electronic components and assemblies. Research is focused on the study of failure mechanisms like electromigration, hot carrier degradation, contact diffusion, dielectric breakdown and on statistical life time prediction. Also off-chip reliability problems are studied : long term drift of thin and thick film resistors in hybrid assemblies, ageing of solder connections on PCBs, reliability of fine-pitch packaging, ╝ The activities of the TFD section consist of research and development of new thin film materials with applications in electronics, opto-electronics and optics. Research focuses on the physics and chemistry of PECVD high quality diamond films; doping and incorporation of impurities in CVD diamond films, plasmadiagnostics (OES, electrical probes, mass spectrometry) during PECVD and PVD film deposition, development of new materials withaz wide band-gap, optical and photo electrical characterisation of thin films, defect spectroscopy and nano scale study of the surface and bulk characteristics of thin films. The activities of the PCC section are situated in the field of physicochemical characterisation of electronic and electro-optical material systems. Some important research topics are : in-situ electron microscopy; failure analysis of electronic components and assemblies; characterisation using SEM, TEM, SAM, AFM, µ focus X-ray, ; fundamental study of quantification problems with SIMS and post-ionisation SIMS.
