Abstract: Through-silicon via dies are described. In an example, a semiconductor die includes a substrate having a device side and a backside. An active device layer is in or on the device side of the substrate. A dielectric structure is over the active device layer. A first die-edge metal guard ring is in the dielectric structure and around an outer perimeter of the substrate. A plurality of metallization layers is in the dielectric structure and within the first die-edge metal guard ring. A plurality of through silicon vias is in the substrate and extend into the dielectric structure and are connected to the plurality of metallization layers. A plurality of backside metallization structures is beneath the backside of the substrate. The plurality of through silicon vias are connected to the plurality of backside metallization structures. A second die-edge metal guard ring is laterally around the plurality of backside metallization structures.

Abstract: Embodiments described herein may be related to apparatuses, processes, and techniques for providing a hermetic seal for a layer of transistors with metal on both sides that are on a substrate. The layer of transistors may be within a die or within a portion of a die. The hermetic seal may include a hermetic layer on one side of the layer of transistors and a hermetic layer on the opposite side of the transistors. In embodiments, one or more metal walls may be constructed through the transistor layer, with metal rings placed around either side of the layer of transistors and hermetically coupling with the two hermetic layers. Other embodiments may be described and/or claimed.
