Abstract: Systems, apparatus, articles of manufacture, and methods for package substrates with stacks of glass layers having different coefficients of thermal expansion are disclosed. An example package substrate includes: a first glass layer including a first through glass via extending therethrough, the first glass layer having a first coefficient of thermal expansion (CTE); and a second glass layer including a second through glass via extending therethrough, the second glass layer having a second CTE different from the first CTE, the first through glass via electrically coupled to the second through glass via.

Abstract: Various techniques for edge stress reduction in glass cores and related devices and methods are disclosed. In one example, a microelectronic assembly includes a glass core having a bottom surface, a top surface opposite the bottom surface, and one or more sidewalls extending between the bottom surface and the top surface, and further includes a panel of an organic material, wherein the glass core is embedded within the panel. In another example, a microelectronic assembly includes a glass core as in the first example, where an angle between a portion of an individual sidewall and one of the bottom surface or the top surface is greater than 90 degrees. In yet another example, a microelectronic assembly includes a glass core as in the first example, and further includes a pattern of a material on one of the one or more sidewalls.
