Glass core substrate for integrated circuit devices and methods of making the same
First Claim
1. A substrate comprising:
- a core comprised of amorphous solid glass, the amorphous solid glass core having a first surface and an opposing second surface;
a number of conductors extending through the amorphous solid glass core beginning at the first surface and ending at the second surface, wherein the number of conductors comprise an opening through the amorphous solid glass core filled with a single conductive material;
at least one dielectric layer and at least one metal layer disposed at the first surface of the amorphous solid glass core, wherein the at least one metal layer at the first surface is electrically coupled with at least one of the conductors;
at least one dielectric layer and a least one metal layer disposed at the second surface of the amorphous solid glass core, wherein the at least one metal layer at the second surface is electrically coupled with at least one of the conductors.

Abstract
Disclosed are embodiments of a glass core substrate for an integrated circuit (IC) device. The glass core substrate includes a glass core and build-up structures on opposing sides of the glass core. Electrically conductive terminals may be formed on both sides of the glass core substrate. An IC die may be coupled with the terminals on one side of the substrate, whereas the terminals on the opposing side may be coupled with a next-level component, such as a circuit board. The glass core may comprise a single piece of glass in which conductors have been formed, or the glass core may comprise two or more glass sections that have been joined together, each section having conductors. The conductors extend through the glass core, and one or more of the conductors may be electrically coupled with the build-up structures disposed over the glass core. Other embodiments are described and claimed.
