Abstract: An IC die package includes a substrate comprising glass and a plurality of holes extending through the glass. A via metallization is present within the holes. A liner is between the via metallization and the glass. The liner can comprise a beta-titanium alloy layer, polymer hydrogel layer and an MXene seed layer, an organic material layer and a metal layer, or an organic material layer between first and second metal layers. A polymer layer may be formed by electrodeposition of charged nanoparticles.

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.

Abstract: The present disclosure is directed to a position-controlled lamination tool or press that includes an array or plurality of pressure sensors and an array or plurality of heating/cooling elements or components, which may be coupled together, for preventing or reducing laminating film or material bleed out and improving thickness variation performance. The pressure sensors may provide a controller, which is coupled to the lamination tool, with real-time feedback on any thickness variations across a substrate panel and the controller may adjust the temperature output of the heating and cooling elements to locally modify the viscosity of the laminating material in one or more regions of the substrate panel to either decrease or increase the flowability of the laminating material.

Abstract: Embodiments disclosed herein include a core for a package substrate. In an embodiment, the core comprises a first substrate with a first surface and a second surface, a first recess into the first surface of the first substrate, a first layer in the first recess, where the first layer is electrically conductive, a second layer over the first layer, where the second layer is a dielectric layer, and a third layer over the second layer, where the third layer is electrically conductive. In an embodiment, the core further comprises a second substrate with a third surface and a fourth surface, where the third surface of the second substrate faces the first surface of the first substrate, a second recess in the third surface of the second substrate, and a fourth layer in the second recess, where the fourth layer is electrically conductive, and the fourth layer contacts the third layer.

Abstract: The present disclosure is directed to a carrier chuck having a base plate with a top surface, a plurality of first magnets positioned in a first region of the top surface, the plurality of first magnets configured to produce a first electromagnetic field to retain or suspend a panel placed on the carrier chuck during panel processing, wherein the first region corresponds to a region of the panel which comprises a magnetic material.

Abstract: Embodiments disclose a package substrate. In an embodiment, the package substrate comprises a core, where the core comprises: a first sub-core, where the first sub-core comprises a glass and a first through glass via (TGV), and a second sub-core, where the second sub-core comprises the glass and a second TGV. In an embodiment, the first TGV directly contacts the second TGV.
