Role in the project

Heraeus Electronics is contributing to WP4 and WP5 and is leading the subtask T4.1.1 ‘Advanced interconnects & substrate materials for GaN packaging’. Within WP4 assembly materials will be developed and applied and in WP5 reliability will be tested and the understanding supported with FE-simulation.

Key contribution

Heraeus Electronics manufactures materials for the packaging of semiconductors and offers services for assembly, simulation, and testing. Main contribution is the development a highly reliable interconnect for power transmission. A Die Top Interconnect System is designed, applied, and tested which allows heavy Cu wire or ribbon bonding on GaN devices. An alternative approach is the development of a fine pitch sinter paste for flip chip application, which will be developed. Testing and FE-Simulation will be applied to understand failure mechanisms in GaN package, and a lifetime model will be derived to apply it to other package designs.
