摘要: Methods and apparatus for processing a substrate include cleaning and self-assembly monolayer (SAM) formation for subsequent reverse selective atomic layer deposition. An apparatus may include a process chamber with a processing volume and a substrate support including a pedestal, a remote plasma source fluidly coupled to the process chamber and configured to produce radicals or ionized gas mixture with radicals that flow into the processing volume to remove residue or oxides from a surface of the substrate, a first gas delivery system with a first ampoule configured to provide at least one first chemical into the processing volume to produce a SAM on the surface of the substrate, a heating system located in the pedestal and configured to heat a substrate by flowing gas on a backside of the substrate, and a vacuum system fluidly coupled to the process chamber and configured to control heating of the substrate.

摘要: Described are methods for forming ruthenium doped niobium nitride barrier layers. The doped barrier layer provides improved adhesion at a thickness of less than about 15 Å. In some embodiments, the doped barrier layers disclosed herein provide improved barrier properties including a lower nitrogen content, a higher ruthenium content, better coverage, thinner layers, or lower line resistance

摘要: Electronic devices and methods of forming electronic devices using a ruthenium or doped ruthenium liner and cap layer are described. A liner with a ruthenium layer and a cobalt layer is formed on a barrier layer. A conductive fill forms a second conductive line in contact with the first conductive line.

摘要: Methods and apparatus for an interconnect formed on a substrate and a method of forming the interconnect thereon. In embodiments, the methods include etching through a hard mask disposed atop a low-k dielectric layer to form a via through the low-k dielectric layer and expose a conductive surface; contacting the conductive surface with dilute hydrofluoric acid to remove contaminants therefrom; removing the hard mask disposed atop the low-k dielectric layer; and applying a remote hydrogen plasma to the conductive surface to form an exposed portion of the conductive surface.

摘要: Methods of forming devices comprise forming a dielectric layer on a substrate, the dielectric layer comprising at least one feature defining a gap including sidewalls and a bottom. The methods include selectively depositing a self-assembled monolayer (SAM) on the bottom of the gap. The SAM comprises a hydrocarbon having a formula of H—C≡C—R, wherein R is a linear alkyl chain or aryl group comprising from 1 to 20 carbon atoms or a formula of R′C═CR″, wherein R′ and R″ independently include a linear alkyl chain or aryl group comprising from 1 to 20 carbon atoms A barrier layer is formed on the SAM before selectively depositing a metal liner on the barrier layer. The SAM is removed after selectively depositing the metal liner on the barrier layer.

摘要: Process recipe data associated a process to be performed for a substrate at a process chamber is provided as input to a trained machine learning model. A set of process recipe settings for the process that minimizes scratching on one or more surfaces of the substrate is determined based on one or more outputs of the machine learning model. The process is performed for the substrate at the process chamber in accordance with the determined set of process recipe settings.

摘要: Provided are methods of forming vias with decreased resistance by selectively depositing a barrier layer on an insulating layer and not on a metallic surface. Some embodiments of the disclosure utilize a planar hydrocarbon to form a blocking layer on metallic surfaces. Deposition is performed to selectively deposit on the unblocked insulating surfaces.
