    Abstract: Glass interposer panels and methods for forming the same are described herein. The interposer panels include a glass substrate core formed from an ion-exchangeable glass. A first layer of compressive stress may extend from a first surface of the glass substrate into the thickness T of the glass substrate core to a first depth of layer D1. A second layer of compressive stress may be spaced apart from the first layer of compressive stress and extending from a second surface of the glass substrate core into the thickness T of the glass substrate core to a second depth of layer D2. A plurality of through-vias may extend through the thickness T of the glass substrate core. Each through-via is surrounded by an intermediate zone of compressive stress that extends from the first layer of compressive stress to the second layer of compressive stress adjacent to a sidewall of each through-via.

    Abstract: Strengthened glass articles having laser etched features, electronic devices, and methods of fabricating etched features in strengthened glass articles are disclosed. In one embodiment, a strengthened glass article includes a first strengthened surface layer and a second strengthened surface layer under a compressive stress and extending from a first surface and a second surface, respectively, of the strengthened glass article to a depth of layer, and a central region between the first strengthened surface layer and the second strengthened surface layer that is under tensile stress. The strengthened glass article further includes at least one etched feature formed by laser ablation within the first surface or the second surface having a depth that is less than the depth of layer and a surface roughness that is greater than a surface roughness of the first surface or second surface outside of the at least one etched feature.

    Abstract: A method of separating a transparent workpiece comprises depositing a sacrificial layer onto a textured surface of the transparent workpiece, the sacrificial layer comprising a refractive index that is less than or equal to a refractive index of the transparent workpiece and greater than or equal to a refractive index of air. A defect-forming laser beam is generated via an optical assembly and used to form a plurality of defects in the transparent workpiece through sacrificial layer. The defect forming laser beam either comprises a pulsed laser beam forming a laser beam focal line in the transparent workpiece or an optical power of greater than or equal a critical power level to induce Kerr effect self-focusing in the transparent workpiece. The transparent workpiece is separated along the contour.
