Abstract

An electronic device includes a carrier substrate with an electronic IC chip mounted on top of the carrier substrate. An encapsulation block on top of the front face of the carrier substrate embeds the IC chip. The encapsulation block has a through-void for positioning and confinement that extends through the encapsulation block to the top of the carrier substrate. At least one electronic component is positioned within the through-void and mounted to the top of the carrier substrate. Solder bumps or pads are located within the through-void to electrically connect the at least one electronic component to the carrier substrate.
