  • Patent number: 12457905
    Abstract: Aspects of the invention are directed to a method of forming an integrated circuit. Both a dielectric layer and a bottom contact are formed with the bottom contact disposed at least partially in the dielectric layer. The bottom contact is subsequently recessed into the dielectric layer to cause the dielectric layer to define two sidewalls bordering regions of the bottom contact removed during recessing. Two sidewall spacers are then formed along the two sidewalls. A landing pad is formed on the recessed bottom contact and between the two sidewall spacers. Lastly, an additional feature is formed on top of the landing pad at least in part by anisotropic etching. In one or more embodiments, the additional feature includes a magnetic tunnel junction patterned at least in part by ion beam etching.

  • Patent number: 12439608
    Abstract: A back side contact structure is provided that directly connects a first electrode of a MRAM, which is present in a back side of a wafer, to a source/drain structure of a transistor. The back side contact is self-aligned to the source/drain structure of the transistor as well as to the first electrode of the MRAM. The close proximity between the MRAM and the source/drain structure increases the speed of the device. MRAM yield is not compromised since no re-sputtering of back side contact metal onto the MRAM occurs.

  • Publication number: 20240147876
    Abstract: A memory cell structure includes a substrate having formed thereon a first electrode and second electrodes physically spaced apart. A phase change material (PCM) cell is formed on the substrate and forms a bridge extending between the first and second electrodes, the phase change material including a first end electrically contacting the first electrode and a second end contacting the second electrode. The phase change material cell includes a thinned surface portion where a surface topography of the phase change material cell is decreased relative to a surface topography of the phase change material cell surface at the first and second ends. The PCM thickness is intentionally gradually tapered to localize the formation of the phase change region. During PCM programming, corresponding to the weight update in machine learning, the phase change of the PCM occurs at the thinnest surface portion and gradually propagates towards the electrodes.
