Abstract: Capacitor structures for integrated circuit devices are provided. Capacitors include proximate dense or highly dense etchstop layers. The dense or highly dense etchstop layer is, for example, a high-k material. Capacitors are, for example, metal-insulator-metal (MIM) capacitors and are useful in DRAM (dynamic random access memory) and eDRAM (embedded dynamic random access memory) structures.

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.

Abstract: Techniques are disclosed for insulating or electrically isolating select vias within a given interconnect layer, so a conductive routing can skip over those select isolated vias to reach other vias or interconnects in that same layer. Such a via blocking layer may be selectively implemented in any number of locations within a given interconnect as needed. Techniques for forming the via blocking layer are also provided, including a first methodology that uses a sacrificial passivation layer to facilitate selective deposition of insulator material that form the via blocking layer, a second methodology that uses spin-coating of wet-recessible polymeric formulations to facilitate selective deposition of insulator material that form the via blocking layer, and a third methodology that uses spin-coating of nanoparticle formulations to facilitate selective deposition of insulator material that form the via blocking layer. Harmful etching processes typically associated with conformal deposition processes is avoided.

Abstract: Techniques are disclosed for providing a decoupled via fill. Given a via trench, a first barrier layer is conformally deposited onto the bottom and sidewalls of the trench. A first metal fill is blanket deposited into the trench. The non-selective deposition is subsequently recessed so that only a portion of the trench is filled with the first metal. The previously deposited first barrier layer is removed along with the first metal, thereby re-exposing the upper sidewalls of the trench. A second barrier layer is conformally deposited onto the top of the first metal and the now re-exposed trench sidewalls. A second metal fill is blanket deposited into the remaining trench. Planarization and/or etching can be carried out as needed for subsequent processing. Thus, a methodology for filling high aspect ratio vias using a dual metal process is provided. Note, however, the first and second fill metals may be the same.
