    摘要: A system and method prevent corrosive elements (or at least the oxidizing agent) from making contact with metal connections at the interface between two layers of a stacked IC device. When layers are positioned in proximity to each other, a cavity is formed at the boundary of the planar surfaces of the layers. This cavity is bounded by a peripheral seal between the layers. In one embodiment, a vacuum is created within the cavity thereby reducing the corrosive atmosphere within the cavity. In another embodiment, the cavity is filled with an inert gas, such as argon. Once the cavity has oxidizing elements reduced, the peripheral seal can be encapsulated to prevent seepage of contaminants into the cavity.

The transformers include at least two inductively coupled inductors. The inductors include a plurality of segments of a first metal layer, a plurality of segments of a second metal layer, a first inductor input, a second inductor input, and a plurality of through silicon vias coupling the plurality of segments of the first metal layer and the plurality of segments of the second metal layer to form a continuous, non-intersecting path between the first inductor input and the second inductor input. The inductors can have a symmetric or asymmetric geometry. The first metal layer can be a metal layer in the back-end-of-line section of the chip. The second metal layer can be located in the redistributed design layer of the chip.

    摘要: Thermal conductivity in a stacked IC device can be improved by constructing one or more active temperature control devices within the stacked IC device. In one embodiment, the control devices are thermal electric (TE) devices, such as Peltier devices. The TE devices can then be selectively controlled to remove or add heat, as necessary, to maintain the stacked IC device within a defined temperature range. The active temperature control elements can be P-N junctions created in the stacked IC device and can serve to move the heat laterally and/or vertically, as desired.

    摘要: Fabrication of a through glass via in a relatively thick glass substrate includes patterning a through glass via hard mask on a surface of the glass substrate. The fabrication also includes wet etching a portion of the glass substrate, through the hard mask, to create a partial through glass via. The wet etching may involve applying a vapor of an oxide etch chemical, such as HF and XeF6, or applying a wet oxide etch chemical, such as HF and XeF6. The fabrication further includes passivating the etched partial through glass via, removing bottom passivation from the partial through glass via, and repeating the etching, passivating and removing to create the through glass via. The resulting through glass via has a scalloped side wall, a vertical profile and a high aspect ratio.

    摘要: A multi-tiered IC device contains a first die including a substrate with a first and second set of vias. The first set of vias extends from one side of the substrate, and the second set of vias extend from an opposite side of the substrate. Both sets of vias are coupled together. The first set of vias are physically smaller than the second set of vias. A second die having a set of interconnects is stacked relative to the first die in which the interconnects couple to the first set of vias.
