A heat dissipation device includes a substrate with a network of thermally-conductive vias and thermally-conductive layers. The substrate has a first surface and a second surface opposite to the first surface. A heat dissipation interface layer including a stack of a first layer made of a first thermally-conductive material and a second layer made of a second thermally-conductive material. The first material is different from the second material. A surface of the first layer is coplanar with the first surface of the substrate. At least one of the thermally-conductive vias of said network supports and is in contact with the first layer. At least one opening thoroughly crosses the stack of the first and second layers. Material of the substrate fills the opening in the first layer.

Thermal dissipation

A cover for an integrated circuit package includes a central plate and a peripheral frame surrounding the central plate. The peripheral frame is vertically spaced from and parallel to the central plate. The peripheral frame includes through openings formed therein. The cover can be used to package a semiconductor chip that is mounted to a substrate.

Cap for package of integrated circuit

An electronic device disclosed herein includes a first conductor layer, a first nonconducting layer, and a second conductor layer in a stacked arrangement. A signal carrying conductive via is formed in the first nonconducting layer and extends between the first conductor layer and the second conductor layer. A shielding conductive via is formed in the first nonconducting layer, is not electrically coupled to the signal carrying conductive via, and substantially completely surrounds the signal carrying conductive via in spaced apart relation thereto.
