Multilayer Composite Materials Vias

摘要

Novel multilayer composite material vias for biological implants are disclosed. The vias comprise two metals, so that the metal more compatible with biological environments is on one end of the via, and the metal more compatible with fabrication of a hermetic package is on the other end of the via.

主权项

1. A multilayer composite material comprising:
an insulating substrate having a first surface and a second surface; at least one via defined in the insulating substrate, wherein the at least one via comprises
at least one layer of a first metal; andat least one layer of a second metal different from the first metal,and wherein the at least one via forms a continuous path from the first surface to the second surface.
