  • Patent number: 7541065
    Abstract: A method is provided for forming a film stack in which a first film including a first polymer is formed on a substrate. A second film, which can include a second polymer other than the first polymer, is formed to have an inner surface disposed on the first film. The second film can have a thickness at which a free energy of the second film would be negative if the second film were disposed directly on the substrate. Desirably, the resulting second film is substantially free of dewetting defects.

  • Patent number: 7483804
    Abstract: A method of real time dynamic CD control in a system for patterning resist coated wafers. The method includes lithographically patterning the resist coated wafers using predetermined exposure dose and focus settings. The method further includes obtaining CD metrology data from test areas on the patterned wafers, where different groups of test areas are selected for two or more of the patterned wafers. A CD metrology data map is constructed using the CD metrology data, adjusted exposure dose and/or focus settings are established using the CD metrology data, and additional wafers are then patterned.

  • Patent number: 7473461
    Abstract: A film stack is provided in which a first film including a first polymer directly contacts a surface of a substrate at which a given material is exposed. A second film, which can include a second polymer other than the first polymer, is formed to have an inner surface contacting the first film. The second film can have a thickness at which a free energy of the second film would be negative if the second film were disposed directly on the substrate. Desirably, the resulting second film is substantially free of dewetting defects.

  • Patent number: 7444196
    Abstract: A patterned structure in a wafer is created using one or more fabrication treatment processes. The patterned structure has a treated and an untreated portion. One or more diffraction sensitivity enhancement techniques are applied to the structure, the one or more diffraction sensitivity enhancement techniques adjusting one or more properties of the patterned structure to enhance diffraction contrast between the treated portion and untreated portions. A first diffraction signal is measured off an unpatterned structure on the wafer using an optical metrology device. A second diffraction signal is measured off the patterned structure on the wafer using the optical metrology device. One or more diffraction sensitivity enhancement techniques are selected based on comparisons of the first and second diffraction signals.

  • Publication number: 20080237214
    Abstract: Methods and heat treatment apparatus for heating a substrate and any layer carried on the substrate during a bake process. A heat exchange gap between the substrate and a heated support is at least partially filled by a gas having a high thermal conductivity. The high thermal conductivity gas is introduced into the heat exchange gap by displacing a lower thermal conductivity originally present in the heat exchange gap when the substrate is loaded. Heat transfer across the heat exchange gap is mediated by the high thermal conductivity gas.

  • Publication number: 20070226674
    Abstract: System and Method for Semiconductor Device Fabrication Using Modeling System and method for using adjustment patterns as well as physical parameters as targets to control mask structure dimensions using optical proximity correction. A preferred embodiment includes defining targets based on definition rules and adjusting mask layer structures based on the targets. The targets comprise structures that are visible in the reproduced pattern as well as targets that affect geometric properties. The targets that affect geometric properties include target sacrificial structures that are selected from one or more of the following groups: actual sacrificial structures that are visible only in an intermediate exposure of the reproduced pattern, virtual sacrificial structures of a mask layer having at least one dimension smaller than a minimum dimension required for resolution, and virtual sacrificial structures not part of the reproduced pattern.

  • Patent number: 7267863
    Abstract: A film stack and method of forming a film stack are provided in which a first film is disposed on a substrate and a second film has an inner surface disposed on the first film. The second film has a thickness smaller than a reference thickness at which the second film would begin to dewet from the substrate if the second film were disposed directly on the substrate. However, the second film is substantially free of dewetting defects because it is disposed overlying the first film which has a first Hamaker constant having a negative value with respect to the substrate.

  • Publication number: 20070037325
    Abstract: A method of forming a thin film is provided in which a film having a first thickness is deposited over a substrate, wherein the first thickness is greater than a thickness at which the initially deposited film begins to dewet from the substrate. The initially deposited film is then stabilized to form a stabilized film. Thereafter, the stabilized film is then thinned to a second thickness, such that the resulting film now has a smaller thickness than the thickness at which the initially deposited film would begin to dewet from the substrate. However, as a result of the prior stabilization, the reduced thickness film remains free of dewetting defects.

  • Publication number: 20060147849
    Abstract: A method is provided for forming a stable thin film on a substrate. The method includes depositing a co-polymer composition having a first component and a second component onto a substrate to form a stable film having a first thickness. The first component has first dielectric properties not enabling the first component by itself to produce the stable film having the first thickness. However, the second component has second dielectric properties which impart stability to the film at the first thickness. In a preferred embodiment, the second component includes a leaving group, and the method further includes first thermal processing the film to cause a solvent but not the leaving group to be removed from the film, after which second thermal processing is performed to at least substantially remove the leaving group from the film. As a result, the film is reduced to a second thickness smaller than the first thickness, and the film remains stable during both the first and the second thermal processing.
