    Abstract: Integrated circuit (IC) devices with stacked two-level backend memory, and associated systems and methods, are disclosed. An example IC device includes a front end of line (FEOL) layer, including frontend transistors, and a back end of line (BEOL) layer above the FEOL layer. The BEOL layer includes a first memory layer with memory cells of a first type, and a second memory layer with memory cells of a second type. The first memory layer may be between the FEOL layer and the second memory layer, thus forming stacked backend memory. Stacked backend memory architecture may allow significantly increasing density of memory cells in a memory array having a given footprint area, or, conversely, reducing the footprint area of the memory array with a given memory cell density. Implementing two different types of backend memory may advantageously increase functionality and performance of backend memory.

    Abstract: A fabrication method and associated integrated circuit (IC) structures and devices that include one or more conductive vias is described herein. In one example, a conductive via is formed from one side of the integrated circuit, and then a portion of the conductive via is widened from a second side of the IC structure opposite the first side. In one example, a resulting IC structure includes a first portion having a first width, a second portion having a second width, and a third portion having a third width, wherein the third portion is between the first portion and the second portion, and the third width is smaller than the first width and the second width. In one such example, the conductive via tapers from both ends towards the third portion between the ends.
