Abstract
In this study, anodically-bondable LTCC (low temperature cofired ceramic) substrates are proposed to provide electrical connective packaging by using novel nano-structured gold. On-chip MEMS compatible fabrication of nanoporous gold (NPG) was developed and its porous structure offers sponge-like functions which forms electrical contacts as well during anodic bonding. A MEMS integrated Si substrate is mechanically sealed to a metal feedthrough LTCC substrate by anodic bonding and its electrical connection is formed by the nanoporous structured pads simultaneously.
