  • Patent number: 10338466
    Abstract: Techniques include providing selective or differential planarization such that different regions of a substrate can have different amounts of material removed. In general, methods herein use photo-reactive generator compounds to generate solubility-changing agents. A specific pattern of light is projected onto a substrate containing such photo-reactive generator compounds to create different concentrations of solubility-changing agent(s) at specific locations across a substrate. As generated solubility-changing agents are diffused into an underlying layer, these concentration differences then control an amount (height or depth) of material removed from a given film or layer at specific spatial locations on the substrate.

  • Patent number: 10338473
    Abstract: The present disclosure concerns a method and system for providing a patterned structure (3p) on an acceptor substrate 4). The method comprises providing a donor substrate (10) arranged between a light source (5) and an acceptor substrate (4). A mask (7) is arranged between the light source (5) and the donor substrate (10). The mask (7) comprises a mask pattern (7p) for patterning light (6). The patterned light (6p) impinging the donor substrate (10) causes the donor material (3) to be released from the donor substrate (10) and transfer to the acceptor substrate (4) to form the patterned structure (3p) thereon. The patterned light (6p) is divided by the mask pattern (7p) into a plurality of separate homogeneously sized beams (6b) simultaneously impinging the donor substrate (10) for causing the donor material (3) to be released from the donor substrate (10) in the form of separate homogeneously sized droplets (3d).

  • Patent number: 10234763
    Abstract: An article is prepared with surface regions having different contact angles. A reactive silane material is attached to a surface having a reactive tail component that is contacted with a first corresponding reactant, followed by imagewise UV exposure to cause imagewise reaction of the reactive tail component and first corresponding reactant, forming reacted regions and latent reaction regions. After rinsing, a second corresponding reactant that is capable of reaction with the reactive moiety is applied. Uniform UV exposure leads to a second reaction product only in the latent reaction regions. After rinsing, first regions comprise exclusively the first reaction product and second regions comprising exclusively the second reaction product. These first and second regions have contact angles that differ by 10-110 degrees. A composition can be applied that is exclusively attracted to either the first regions or the second regions, but not to both the first and second regions.

  • Patent number: 10139728
    Abstract: A method for curing photosensitive polyimide (PSPI) films includes the steps of: depositing a PSPI film on a selected substrate, and curing the film by microwave heating at a selected temperature from about 200 to 340° C. in a selected atmosphere containing an oxygen concentration from about 20 to 200,000 ppm. The process atmosphere may be static or flowing. The addition of oxygen improves the removal of acrylate residue and improves the Tg of the cured film, while the low processing temperature characteristic of the microwave process prevents the oxygen from damaging the polyimide backbone. The method may further include the steps of photopatterning and developing the PSPI film prior to curing. The process is particularly suitable for dielectric films on silicon for electronic applications.

  • Patent number: 10090357
    Abstract: A first photoresist pattern and a second photoresist pattern are formed over a substrate. The first photoresist pattern is separated from the second photoresist pattern by a gap. A chemical mixture is coated on the first and second photoresist patterns. The chemical mixture contains a chemical material and surfactant particles mixed into the chemical material. The chemical mixture fills the gap. A baking process is performed on the first and second photoresist patterns, the baking process causing the gap to shrink. At least some surfactant particles are disposed at sidewall boundaries of the gap. A developing process is performed on the first and second photoresist patterns. The developing process removes the chemical mixture in the gap and over the photoresist patterns. The surfactant particles disposed at sidewall boundaries of the gap reduce a capillary effect during the developing process.

  • Patent number: 10073342
    Abstract: A substrate having a target material layer is provided. A first hard mask layer, a second hard mask layer, and a photoresist layer are formed on the target material layer. The photoresist layer is transferred into first patterns on the second hard mask layer. Regions of the second hard mask layer not protected by the first patterns are etched away, thereby forming second patterns. The first patterns are trimmed to form trimmed features. A conformal spacer material layer is deposited on the trimmed features, the second patterns, and the first hard mask. The spacer material layer is etched to form first spacers on sidewalls of the trimmed features, and second spacers on sidewalls of the second patterns. The trimmed features are removed. Regions of the second patterns not protected by the first spacers are removed, thereby forming patterns with a reduced, fine pitch.

  • Patent number: 10061199
    Abstract: Patterning methods for creating features with sub-resolution dimensions that are self-aligned in photoresist materials. Techniques include selectably creating antispacers (or spacers) in soft materials, such as photoresist. A photoresist without a photo acid generator is deposited on a relief pattern of a solubility-neutralized photoresist material having a photo acid generator. A photomask then defines where photo acid is generated from a corresponding activating exposure. Photo acid is then diffused into the photoresist, that is free of the photo acid generator, to cause a solubility shift for subsequent development. These selectably-created antispacers can be line segments having widths defined by acid diffusion lengths, which can be widths of 1 nanometer to tens of nanometers. Moreover, the creation of antispacers, their location, and length, can be controlled using a photomask.
