Fast Filling of Microvia by Pre-Settling Particles and Following Cu Electroplating

Microvia interconnectors are a critical element of 3D packaging technology, as they provide the shortest interconnection path between stacked chips. However, low efficiency of microvia filling is a long-standing problem. This study proposed a two-step method to enhance the electroplating filling eff...
