    Abstract: Embodiments herein include void-free material depositions on a substrate (e.g., in a void-free trench-filled (VFTF) component) obtained using directional etching to remove predetermined portions of a seed layer covering the substrate. In several embodiments, directional etching followed by selective deposition can enable fill material (e.g., metal) patterning in tight spaces without any voids or seams. Void-free material depositions may be used in a variety of semiconductor devices, such as transistors, dual work function stacks, dynamic random-access memory (DRAM), non-volatile memory, and the like.

  • Patent number: 11735420
    Abstract: Methods of depositing a film selectively onto a first material relative to a second material are described. The substrate is pre-cleaned by heating the substrate to a first temperature, cleaning contaminants from the substrate and activating the first surface to promote formation of a self-assembled monolayer (SAM) on the first material. A SAM is formed on the first material by repeated cycles of SAM molecule exposure, heating and reactivation of the first material. A final exposure to the SAM molecules is performed prior to selectively depositing a film on the second material. Apparatus to perform the selective deposition are also described.
