Patent ID: 8592969

Claim:
A semiconductor device, comprising: a substrate having a bottom face on which are formed a plurality of external electrical connection pads; at least one integrated-circuit chip installed inside the substrate; at least one electronic and/or electric component also installed inside the substrate at a position above the chip; wherein the substrate comprises an electrical connection network selectively connecting the chip, the component and first ones of the electrical connection pads on the bottom face; at least one screen comprising a portion substantially parallel to the bottom face and a plurality of electrical connection vias connecting this portion to second ones of the electrical connection pads on the bottom face; wherein the chip is surrounded by the plurality of electrical connection vias of the screen; wherein the at least one screen comprises: a first screen made of an electrically conductive material and comprising a first portion extending between the chip and the component and a plurality of first electrical connection vias connecting this first portion to a first plurality of the second ones of the electrical connection pads, this plurality of first vias being placed around the periphery of the chip; and a second screen made of electrically conductive material and comprising a second portion positioned above the component and a plurality of second electrical connection vias connecting this second portion to a second plurality of the second ones of the electrical connection pads, this plurality of second vias being placed around and at a distance from the plurality of first vias.
