  • Patent number: 11970776
    Abstract: Provided herein are low resistance metallization stack structures for logic and memory applications and related methods of fabrication. In some embodiments, thin metal oxynitride or metal nitride nucleation layers are deposited followed by deposition of a pure metal conductor. The nucleation layer is amorphous, which templates large pure metal film grain growth and reduced resistivity. Further, certain embodiments of the methods described below convert most or all of the metal oxynitride nucleation layer to a pure metal layer, further lowering the resistivity.

  • Publication number: 20240136192
    Abstract: Provided herein are low resistance metallization stack structures for 3D-NAND applications and related methods of fabrication. In some embodiments, thin metal oxynitride nucleation layers are deposited on dielectric material followed by deposition of a pure metal conductor using process conditions that increase non-molybdenum component element content at the oxynitride-dielectric interface. Certain embodiments of the methods described below convert less than all of the metal oxynitride nucleation layer to a pure metal layer, further lowering the resistivity.

  • Publication number: 20240100658
    Abstract: A powered ratchet includes a motor, a mounting portion, and an output member configured to rotate in response to activation of the motor. The output member defines a drive axis. The powered ratchet also includes a release mechanism configured to selectively couple an anvil to the output member. The release mechanism includes a cover coupled to the mounting portion with a track and a locking member positioned between the mounting portion and the cover and operable to slide within the track between a locked position, in which the locking member engages the anvil to secure the anvil to the output member for co-rotation therewith, and a release position, in which the locking member is disengaged from the anvil to facilitate removal of the anvil. The release mechanism also includes a biasing member biasing the locking member to the locked position.

  • Publication number: 20230290680
    Abstract: Provided herein are methods and apparatuses for forming metal films such as tungsten (W) and molybdenum (Mo) films on semiconductor substrates. The methods involve forming a reducing agent layer, then exposing the reducing agent layer to a metal precursor to convert the reducing agent layer to a layer of the metal. In some embodiments, the reducing agent layer is a silicon- (Si-) and boron- (B-) containing layer. The methods may involve forming the reducing agent layer at a first substrate temperature, raising the substrate temperature to a second substrate temperature, and then exposing the reducing agent layer to 10 the metal precursor at the second substrate temperature. The methods may be used to form fluorine-free tungsten or molybdenum films in certain embodiments. Apparatuses to perform the methods are also provided.

  • Publication number: 20220375792
    Abstract: Embodiments of methods of filling features with molybdenum (Mo) include depositing a first layer of Mo in a feature including an opening and an interior and non-conformally treating the first layer such that regions near the opening preferentially treated over regions in the interior. In some embodiments, a second Mo layer is deposited on the treated first layer. Embodiments of methods of filling features with Mo include controlling Mo precursor flux to transition between conformal and non-conformal fill.
