  • Publication number: 20240160100
    Abstract: Embodiments disclosed herein may include a method for developing a photopatterned metal oxo photoresist. In an embodiment, the method may include pre-treating the photopatterned metal oxo photoresist with a pre-treatment process, developing the photopatterned metal oxo photoresist with a thermal dry develop process to selectively remove a portion of the photopatterned metal oxo photoresist and form a resist mask. In an embodiment, the thermal dry develop process includes a first sub-operation, and a second sub-operation that is different than the first sub-operation. In an embodiment, the process further includes post-treating the resist mask with a post-treatment process.

  • Patent number: 11821070
    Abstract: Methods of depositing metal films comprising exposing a substrate surface to a first metal precursor followed by a non-oxygen containing reducing agent comprising a second metal to form a zero-valent first metal film are described. The reducing agent has a metal center that is more electropositive than the metal center of the first metal precursor. In some embodiments, methods of depositing ruthenium films are described in which a substrate surface is exposed to a ruthenium precursor to form a ruthenium containing film on the substrate surface followed by exposure to a non-oxygen containing reducing agent to reduce the ruthenium containing film to a zero-valent ruthenium film and generate an oxidized form of the reducing agent.

  • Publication number: 20220301887
    Abstract: Embodiments of this disclosure provide methods for etching ruthenium. A halide-containing-gas is flowed into a substrate processing chamber, and then an oxygen-containing gas is flowed into the substrate processing chamber. The methods may include atomic layer etching (ALE). The methods may be conducted at higher processing chambers, permitting deposition and etching of ruthenium to be conducted in the same processing chamber.

  • Patent number: 11332488
    Abstract: Metal coordination complexes comprising at least one diazabutadiene based ligand having a structure represented by: where R1 and R4 are selected from the group consisting of C4-C10 alkyl groups; and R2 and R3 are each independently selected from the group consisting of H, C1-C6 alkyl, cycloalkyl, or aryl groups and the difference in the number of carbons in R2 and R3 is greater than or equal to 2. Processing methods using the metal coordination complexes are also described.

  • Publication number: 20210066592
    Abstract: Methods of depositing a metal-organic oxide film by exposing a substrate surface to a metal-organic precursor and an oxidant are described. The metal-organic oxide film has the general formula MOxCy, wherein M comprises one or more of a transition metal, a lanthanide, or a boron group element, x is a whole number in a range of 1 to 6, and y is a number in a range of greater than 0 to 0.5.

  • Patent number: 10790188
    Abstract: Methods for filling a substrate feature with a seamless ruthenium gap fill are described. The methods include depositing a ruthenium film, oxidizing the ruthenium film to form an oxidized ruthenium film, reducing the oxidized ruthenium film to a reduced ruthenium film and repeating the oxidation and reduction processes to form a seamless ruthenium gap fill.
