    摘要: By filling an air gap between tiers of a stacked IC device with a thermally conductive material, heat generated at one or more locations within one of the tiers can be laterally displaced. The lateral displacement of the heat can be along the full length of the tier and the thermal material can be electrically insulating. Through silicon-vias (TSVs) can be constructed at certain locations to assist in heat dissipation away from thermally troubled locations.

    摘要: A method for forming a magnetic tunnel junction (MTJ) for magnetic random access memory (MRAM) using two masks includes depositing over an interlevel dielectric layer containing an exposed first interconnect metallization, a first electrode, a fixed magnetization layer, a tunneling barrier layer, a free magnetization layer and a second electrode. An MTJ structure including the tunnel barrier layer, free layer and second electrode is defined above the first interconnect metallization by a first mask. A first passivation layer encapsulates the MTJ structure, leaving the second electrode exposed. A third electrode is deposited in contact with the second electrode. A second mask is used to pattern a larger structure including the third electrode, the first passivation layer, the fixed magnetization layer and the first electrode. A second dielectric passivation layer covers the etched plurality of layers, the first interlevel dielectric layer and the first interconnect metallization.
