摘要:
Package assemblies for and methods of packaging integrated circuit chips are described. Disclosed package assemblies have spacers and recessed regions comprising IC chips. Architectural structures are provided that enable, for example, three dimensional (3D) packaging (or system in package (SiP) or multi chip modules), systems on chip 3D packaging, and hybrid 3D bonding. Embodiments of the invention can be used, for example, to create logic to memory, memory to memory, and logic to logic interface stacking assemblies.

An encapsulated die (100, 401) comprises a substrate (110, 510) having a first surface (111), an opposing second surface (112), and intervening side surfaces (113), with active devices located at the first surface of the substrate. The active devices are connected by a plurality of electrically conductive layers (120, 520) that are separated from each other by a plurality of electrically insulating layers (125, 525). A protective cap (130, 530) is located over the first surface of the substrate contains an interconnect structure (140) exposed at a surface (131) thereof. In another embodiment, a microelectronic package (200) comprises a package substrate (250) with an encapsulated die (100) such as was described above embedded therein.

Methods of forming a microelectronic packaging structure and associated structures formed thereby are described. Those methods may include attaching a die to a carrier material, wherein the carrier material comprises a top layer and a bottom layer separated by an etch stop layer; forming a dielectric material adjacent the die, forming a coreless substrate by building up layers on the dielectric material, and then removing the top layer carrier material and etch stop layer from the bottom layer carrier material.
