摘要: An overview of the different metal bonding techniques used for 3D integration is presented. Key parameters such as surface preparation, temperature and duration annealing, achievable wafer-to-wafer alignment electrical results are reviewed. A special focus done on direct patterned metal/dielectric surfaces. mechanism copper proposed based toughness measurements, SAM, XRR, XRD, TEM analysis. Dedicated characterization
