A pinned layer is disposed in the MTJ such that a free layer of the MTJ can couple to a drain of an access transistor when provided in a magnetic random access memory (MRAM) bitcell. This structure alters the write current flow direction to align the write current characteristics of the MTJ with write current supply capability of an MRAM bitcell employing the MTJ.

An anti-ferromagnetic material (AFM) layer is provided on the pinned layer to fix pinned layer magnetization. To provide enough area for depositing the AFM layer to secure pinned layer magnetization, a pinned layer having a pinned layer surface area greater than a free layer surface area of the free layer is provided.

Abstract: An electrostatic discharge (ESD) protection device is fabricated in a vertical space between active layers of stacked semiconductor dies thereby utilizing space that would otherwise be used only for communication purposes. The vertical surface area of the through silicon vias (TSVs) is used for absorbing large voltages resulting from ESD events. In one embodiment, an ESD diode is created in a vertical TSV between active layers of the semiconductor dies of a stacked device. This ESD diode can be shared by circuitry on both semiconductor dies of the stack thereby saving space and reducing die area required by ESD protection circuitry.

Abstract: 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 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.
