Formation of a nano-porous structured Cu layer by selective etching of a brass layer and sinter-bonding to achieve direct Cu–Cu bonding

A nano porous structured (NPS) Cu layer was fabricated by a Zn plating-annealing-selective etching process. Furthermore, sinter-bonding was performed by thermocompression after forming the NPS Cu layer instead of the conventional paste sinter-bonding process. The sinter-bonding produced a dense Cu–C...
