Moisture-proof electrical circuit high density interconnect module and method for making same

摘要

A moisture-proof integrated circuit module includes at least one integrated circuit component in a high density interconnect (HDI) structure fabricated by applying to a substrate successive multiple ply sequences having a plurality of via holes therein. The sequences overlie the component(s) and the module substrate, and each sequence includes a dielectric film and a plurality of lands comprised of metal that extends into the vias of the sequence to provide electrical interconnections. The module includes at least one moisture barrier film to prevent penetration of moisture through the module to the circuit component(s).
