  • Patent number: 11411174
    Abstract: A plasma enhanced chemical vapor deposition (PECVD) method is disclosed for forming a SiON encapsulation layer on a magnetic tunnel junction (MTJ) sidewall that minimizes attack on the MTJ sidewall during the PECVD or subsequent processes. The PECVD method provides a higher magnetoresistive ratio for the MTJ than conventional methods after a 400° C. anneal. In one embodiment, the SiON encapsulation layer is deposited using a N2O:silane flow rate ratio of at least 1:1 but less than 15:1. A N2O plasma treatment may be performed immediately following the PECVD to ensure there is no residual silane in the SiON encapsulation layer. In another embodiment, a first (lower) SiON sub-layer has a greater Si content than a second (upper) SiON sub-layer. A second encapsulation layer is formed on the SiON encapsulation layer so that the encapsulation layers completely fill the gaps between adjacent MTJs.

  • Patent number: 11367682
    Abstract: This disclosure is directed to systems and methods for maskless gap integration in interconnects having one or more vias above one or more interconnect lines (for example, metal interconnect lines). In various embodiments, the systems and methods described in the disclosure may serve to reduce electrical shorting between adjacent vias in the interconnects. In one embodiment, a spacer layer may be provided to mask portions of an interlayer dielectric (ILD) in the interconnect. These masked portions of the ILD can protect regions between adjacent interconnect lines from electrical shorting during subsequent metal layer depositions in a fabrication sequence of the interconnects. Further, in various embodiments, the vias may enclose a gap (for example, an air gap) without the need for additional masking steps, for example, without the need for additional lithography steps.

  • Patent number: 11264480
    Abstract: Incorporation of metallic quantum dots (e.g., silver bromide (AgBr) films) into the source and drain regions of a MOSFET can assist in controlling the transistor performance by tuning the threshold voltage. If the silver bromide film is rich in bromine atoms, anion quantum dots are deposited, and the AgBr energy gap is altered so as to increase Vt. If the silver bromide film is rich in silver atoms, cation quantum dots are deposited, and the AgBr energy gap is altered so as to decrease Vt. Atomic layer deposition (ALD) of neutral quantum dots of different sizes also varies Vt. Use of a mass spectrometer during film deposition can assist in varying the composition of the quantum dot film. The metallic quantum dots can be incorporated into ion-doped source and drain regions. Alternatively, the metallic quantum dots can be incorporated into epitaxially doped source and drain regions.
