Electronic structures and methods of assembly are described in which a lid with pocket sidewalls is mounted on a routing substrate such that the pocket sidewalls laterally surround an electronic component and provide a barrier to outflow of the thermal interface layer outside of the pocket sidewalls, and in particular a thermal interface layer including a liquid metal film.

A method includes attaching a permeable plate to a metal lid, with the permeable plate including a metallic material, and dispensing a liquid-metal-comprising media to a first package component. The first package component is over and bonded to a second package component. The liquid-metal-comprising media includes a liquid metal therein. The method further includes attaching the metal lid to the second package component. During the attaching, the liquid-metal-comprising media migrates into the permeable plate to form a composite thermal interface material.

A package structure and a method of manufacturing a package structure are provided. The package structure includes a first substrate, a first electronic component, a second substrate and a second electronic component. The first electronic component is disposed over a first through hole of the first substrate. The first electronic component is electrically connected to a first patterned circuit layer of the first substrate through an extending portion of the first patterned circuit layer extending beyond a sidewall of the first through hole. The second electronic component is disposed over a second through hole of the second substrate. The second electronic component is electrically connected to a second patterned circuit layer of the second substrate through an inner extending portion of the second patterned circuit layer extending beyond a sidewall of the second through hole.

A semiconductor device package and a method of manufacturing a semiconductor device package are provided. The semiconductor device package includes a carrier, a first component, a second component, and a protective element. The first component and the second component are arranged side by side in a first direction over the carrier. The protective element is disposed over a top surface of the carrier and extending from space under the first component toward a space under the second component. The protective element includes a first portion and a second portion protruded oppositely from edges of the first component by different distances, and the first portion and the second portion are arranged in a second direction angled with the first direction.
