An electronic substrate may be fabricated having a core comprising a laminate including a metal layer between a first insulator layer and a second insulator layer, a metal via through the core, and metallization features on a first side and a second side of the core, wherein first ones of the metallization features are embedded within dielectric material on the first side of the core, and wherein a sidewall of the dielectric material and of the first insulator layer defines a recess over an area of the metal layer. In an embodiment of the present description, an integrated circuit package may be formed with the electronic substrate, wherein at least two integrated circuit devices may be attached to the electronic substrate. In a further embodiment, the integrated circuit package may be electrically attached to an electronic board. Other embodiments are disclosed and claimed.
