This work focuses on the EU-funded project "RADICAL". RADICAL aims to develop a brand-new way of detecting atmospheric radicals in real-time. This will be a small, low-cost electronic sensor that will ‘sniff’ out short-lived radicals such as hydroxyl and nitrate, which play a key intermediary role in day- and night-time air quality.The project has 6 collaborations. The team at HZDR focuses on the fabrication and electrical characterization of junctionless transistors (JNT) which will be further processed by collaboration partners for sensing application. A junctionless transistor consists of a highly doped nanowire channel where the flow of carriers is controlled by the gate. For fabrication of JNTs, the intrinsic silicon-on-insulator (SOIs) are doped with ion implantation and flash lamp annealing is performed for dopant activation. The nanowires are fabricated following a top-down approach using EBL and ICP-RIE. Electrical characterization of the fabricated devices is performed by back- and top-gate architectures.

Institute of Electronics Packaging and Assembly Technology (IAVT-ZmP), TU DresdenPart of the research project "Warpage_ZUV" which focusses on Investigation on the Warpage Behaviour and Failure Assessment of Ball Grid Array (BGA) Components.Circuit boards and components of electronic assemblies are characterized by the construction of various materials, like metals and polymers. Their different coefficients of thermal expansion lead to deformation under thermal stress. These deformations are particularly critical for large components such as Ball Grid Array (BGA) and can lead to errors and failure during assembly. Focused on: • Failure Assessment of Ball Grid Array (BGA) Components• Monitoring temperature change experiments (Thermoire Measurements)• Surface Topographical characterization• Deformation and Bending test measurements.
