  • Patent number: 10811595
    Abstract: Techniques are disclosed for forming a logic device including integrated spin-transfer torque magnetoresistive random-access memory (STT-MRAM). In accordance with some embodiments, one or more magnetic tunnel junction (MTJ) devices may be formed within a given back-end-of-line (BEOL) interconnect layer of a host logic device. A given MTJ device may be formed, in accordance with some embodiments, over an electrically conductive layer configured to serve as a pedestal layer for the MTJ's constituent magnetic and insulator layers. In accordance with some embodiments, one or more conformal spacer layers may be formed over sidewalls of a given MTJ device and attendant pedestal layer, providing protection from oxidation and corrosion. A given MTJ device may be electrically coupled with an underlying interconnect or other electrically conductive feature, for example, by another intervening electrically conductive layer configured to serve as a thin via, in accordance with some embodiments.

  • Patent number: 9911689
    Abstract: Techniques are disclosed for forming a through-body-via (TBV) isolated coaxial capacitor in a semiconductor die. In some embodiments, a cylindrical capacitor provided using the disclosed techniques may include, for example, a conductive TBV surrounded by a dielectric material and an outer conductor plate. The TBV and outer plate can be formed, for example, so as to be self-aligned with one another in a coaxial arrangement, in accordance with some embodiments. The disclosed capacitor may extend through the body of a host die such that its terminals are accessible on the upper and/or lower surfaces thereof. Thus, in some cases, the host die can be electrically connected with another die to provide a die stack or other three-dimensional integrated circuit (3D IC), in accordance with some embodiments. In some instances, the disclosed capacitor can be utilized, for example, to provide integrated capacitance in a switched-capacitor voltage regulator (SCVR).
