Thesis »Development of a tacking agent for sintering applications in microelectronic packaging«

The Fraunhofer-Gesellschaft (www.fraunhofer.com) currently operates 76 institutes and research units throughout Germany and is a leading applied research organization. Around 32 000 employees work with an annual research budget of 3.4 billion euros.

In response to increasing reliability requirements in power electronics and the cost advantage over silver sintering, copper sintering is increasingly becoming the focus of research in microelectronic packaging technology. One challenge, however, is the lack of tacking in dried copper pastes and preforms after the chips have been placed. Especially in series production, the placed chips can shift and thus negatively affect the sintering quality. The aim of this work is therefore to develop a tacking agent that is compatible with the sintering process, fixes the chips and, if necessary, has a reducing effect on the copper surface.

What you will do

Testing of reducing agents, binding agents and other chemicals and fixing the quantities on the properties of the tacking agent
Chemical investigations of the tacking agents developed
Analysis of samples sintered with tacking agent regarding residues and performance
Literature research about the composition of tacking agents for soldering and the requirements for sintering
