Abstract:
Embodiments of the invention provide methods for selective film deposition using a surface pretreatment. According to one embodiment, the method includes providing a substrate containing a dielectric layer and a metal layer, exposing the substrate to a reactant gas containing a molecule that forms self-assembled monolayers (SAMs) on the substrate, and thereafter, selectively depositing a metal oxide film on a surface of the dielectric layer relative to a surface of the metal layer by exposing the substrate to a deposition gas.
Abstract:
An apparatus and method for uniformly holding a substrate without flexure or bending of the substrate, thereby enabling accurate shape measurements of the substrate such as wafer curvature, z-height values and other surface characteristics. Techniques include using a liquid as a supporting surface for a substrate thereby providing uniform support. Liquid used has a same specific gravity of a substrate being supported so that the substrate can float on the liquid without sinking. Uniform support of the substrate enables precision metrology.
Abstract:
A processing chamber system includes a substrate mounting module configured to secure a substrate within a first processing chamber. The system also includes a first deposition module configured to apply a light-sensitive film to a front side surface of the substrate, and a second deposition module configured to apply a film layer to a backside surface of the substrate. The front side surface is opposite to the backside surface of the substrate. A substrate has a bare backside surface with a first coefficient of friction. A film layer is formed onto the backside surface of the substrate. The film layer formed on the backside surface of the substrate has a second coefficient of friction. The second coefficient of friction is lower than the first coefficient of friction.
Abstract:
Methods for processing a substrate are provided. The method includes receiving a substrate. The substrate has a front side surface, a backside surface, and a side edge surface. The method also includes coating the front side surface, the backside surface and the side edge surface with a self-assembled monolayer and exposing an area of interest with actinic radiation. The actinic radiation causes a de-protection reaction within the self-assembled monolayer within the central region. The method also includes removing the self-assembled monolayer from the area of interest while the self-assembled monolayer remains on remaining surfaces of the substrate.

Methods and systems for coating a substrate with a fluid are described. In an embodiment, a method may include receiving a substrate in a substrate processing unit, the substrate having one or more physical features formed on a surface of the substrate. The method may include introducing a gas into an environment of the surface of the substrate. Additionally, the method may include applying a fluid to the surface of the substrate, wherein the gas facilitates distribution of the fluid relative to the one or more physical features formed on the surface of the substrate. The method may further include controlling one or more processing parameters related to distribution of the fluid in order to achieve device formation objectives.
Abstract:
Techniques disclosed herein, provide a method and fabrication structure for accurately increasing feature density for creating high-resolution features and also for cutting on pitch of sub-resolution features. Techniques include using multiple materials having different etch characteristics to selectively etch features and create cuts or blocks where specified. A multiline layer is formed of three or more different materials that provide differing etch characteristics. Etch masks, including interwoven etch masks, are used to selectively etch cuts within selected, exposed materials. Structures can then be cut and formed. Forming structures and cuts can be recorded in a memorization layer, which can also be used as an etch mask.
Abstract:
A capacitor structure and method of forming thereof on a substrate is described. The capacitor structure includes a substrate having a plurality of capacitor electrodes formed within an insulative retaining material, and a collar layer structure in contact with the plurality of capacitor electrodes, wherein the collar layer structure interconnects the plurality of capacitor electrodes and exposes the underlying insulative retaining material through openings having an unguided, random self-assembly pattern. Furthermore, the insulative retaining material may be removed from the capacitor structure. The method includes using a self-assembly process to form the interconnecting collar layer structure.
Abstract:
Techniques herein include a process chamber for depositing thin films to backside surfaces of wafers to reduce wafer bowing and distortion. A substrate support provides an annular perimeter seal around the bottom and/or side of the wafer which allows the majority of the substrate backside to be exposed to a process environment. A supported wafer separates the chamber into lower and upper chambers that provide different process environments. The lower section of the processing chamber includes deposition hardware configured to apply and remove thin films. The upper section can remain a chemically inert environment, protecting the existing features on the top surface of the wafer. Multiple exhausts and differential pressures are used to prevent deposition gasses from accessing the working surface of a wafer.
