Abstract
Methods and systems for a thin sandwich embedded package are disclosed and may include bonding a semiconductor die to a first surface of a substrate, dispensing a bond line on the first surface of the substrate and the die, and bonding an interposer to the substrate and die using the dispensed bond line. The bond line may fill the volume between the interposer and the substrate or may fill the volume between the interposer and the die but not between the interposer and the substrate. A cavity structure may be formed on the interposer and/or substrate, wherein the die may be situated within a cavity formed by the cavity structure when the interposer is bonded to the substrate and die. The cavity structure may comprise solder resist. Contacts may be formed on the cavity structure using low volume pad finish metals to electrically couple the interposer to the substrate.
