Such bonding voids can be detrimental to the electrical properties of the devices being fabricated.In this study we have deposited W-particles with e-beam assisted deposition on the surface of SiCN-coated wafers, proceeded to bonding the wafers with a blanket counterpart and inspected the resulting bonding voids with a Scanning Acoustic Microscope.We could obtain a correlation between the sizes of the deposited particles and the respective induced voids – an amplification factor of 50x. Such correlation allows determining the sensitivity of bonding voids to the dimensions of particles at the bonding interface.engCorrelation between particles and induced voids at the bonding interfaceProceedings paper10.1109/asmc69324.2026.11551198WOS:001813326200029
