Patent ID: 8455994

Claim:
An electronic module comprising: a dielectric substrate having a first surface and a second surface; an installation cavity extending through the dielectric substrate and having a perimetrical side wall between the first surface and the second surface; a first wiring layer on the first surface of the dielectric substrate; a second wiring layer on the second surface of the dielectric substrate; a feed through conductor on the perimetrical side wall of the installation cavity and electrically connecting at least one conductor in the first wiring layer to at least one conductor in the second wiring layer; at least one semiconductor component at least partially inside the installation cavity; a first insulating layer on the second wiring layer; a second insulating layer on the first wiring layer; a third wiring layer on the first insulating layer; first microvias inside the first insulating layer and making electrical connections between the second wiring layer and the third wiring layer; second microvias electrically connecting the at least one semiconductor component to at least one of the second wiring layer and the third wiring layer; a fourth wiring layer on the second insulating layer; and third microvias inside the second insulating layer and making electrical connections between the first wiring layer and the fourth wiring layer.
