Abstract
Embodiments disclosed herein include an apparatus that includes a substrate that includes a glass layer. In an embodiment, a first region of the substrate has a first porosity and a second region of the substrate has a second porosity that is higher than the first porosity. In an embodiment, the second region is at an edge of the substrate. In an embodiment, the substrate further includes a via that passes through a thickness of the substrate.
Claims20
An apparatus, comprising:
- a substrate that comprises a glass layer, wherein a first region of the substrate has a first porosity and a second region of the substrate has a second porosity that is higher than the first porosity, and wherein the second region is at an edge of the substrate;
- and
- a via through a thickness of the substrate.
An apparatus, comprising:
- a glass core, wherein the glass core comprises:
- a first region that comprises a first porosity;
- and
- a second region that surrounds a perimeter of the first region, wherein the second region comprises a second porosity that is higher than the first porosity;
- and
- a buildup layer over the glass core, wherein the buildup layer has a first width that is narrower than a second width of the glass core.
