MEMORY DEVICE WITH HIGH RESISTIVITY THERMAL BARRIER

Abstract:

Methods, systems, and devices for a memory device with a high resistivity thermal barrier are described. In some examples a barrier material may be positioned over a memory cell region, an oxide region, and/or a through-silicon via (TSV). The barrier may include a first region above the memory cell region and a second region above the TSV. A process, such as a plasma treatment, may be applied to the barrier, which may result in the first and second regions having different thermal resistivities (e.g., different densities). Accordingly, due to the different thermal resistivities, the memory cells may be thermally insulated from thermal energy generated in the memory device.
