Abstract
Cold-sprayed aluminum capacitors on lead frame metal foils are provided for applications in 3D power package integration. This additive manufacturing process allows pre-patterned low-temperature processing of aluminum electrodes on metal lead frames, insulated metal substrates or even heat-spreaders and cold-plates. Cold-sprayed capacitors can eliminate several process integration and reliability issues that are associated with traditional discrete surface-assembled capacitors.
