A lid has a heat conductive substrate, a crystallized amorphous silicon layer and a native silicon oxide layer formed on the crystallized amorphous silicon layer. Another embodiment has a lid with a copper substrate and a native silicon oxide layer connected to the substrate by at least one intermediate layer. A method of providing a heat path through an integrated circuit package includes providing a substrate with an exterior layer of native silicon oxide and interfacing the layer of native silicon oxide with a layer of thermal interface material.

Lid for integrated circuit package

An integrated circuit package includes a substrate/interposer assembly having a plurality of conductive contacts and a plurality of conductive posts, such as copper posts, electrically coupled to at least some of the conductive contacts in the substrate/interposer assembly. The conductive posts are surrounded by a protective dielectric, such as a photoimageable dielectric (PID). An integrated circuit die may be disposed on the substrate/interposer assembly within an interior space surrounded by the dielectric. An additional integrated circuit die may be provided in a package-on-package (POP) configuration.

Conductive post protection for integrated circuit packages

A lid comprising a heat conductive substrate and a native silicon oxide layer connected to said substrate by at least one intermediate layer; a lidded integrated circuit package; and a method of providing a heat path through an integrated circuit package comprising providing a substrate with an exterior layer of native silicon oxide and interfacing the layer of native silicon oxide with a layer of thermal interface material.
