    Abstract: Disclosed are embodiments of a bi-layer bottom anti-reflective coating (BARC) with graded optical properties (i.e., a graded refractive index) and a method of forming the BARC. The BARC is formed by sequentially coating two BARC layers onto a substrate. Each BARC layer comprises a polymer and an optical component, each has slightly different optical properties, and each is processed such that either the polymers partially intermix or the optical component partially diffuses between the layers in order to create a graded chromophore concentration across the resulting BARC. Thus, a gradual transition of optical properties is created from the substrate/BARC interface to the BARC/photo-resist interface.

  • Patent number: 7250247
    Abstract: A method for fabricating an integrated circuit using a photo-lithographic process includes the steps of placing at least two anti-reflective coating layers between a reflective surface and another material. The indices of refraction, absorptions, and thicknesses of the at least two anti-reflective coating layers are chosen such that the amplitudes and phase differences of radiation reflected from the anti-reflective coating layers, as well as any other reflective surfaces below the anti-reflective coating layers, mutually cancel when combined. The invention may be practiced using more than two layers of anti-reflective coating. Multiple layers of anti-reflective coating may be used below an inter-level dielectric, in which case they may serve the additional purpose of functioning as an etch-stop.

  • Patent number: 7129025
    Abstract: A fabrication method of three-dimensional microstructures is to fabricate a real 3D microstructure. First, a substrate is coated with an anti-reflection layer to absorb reflected exposure light, and then the anti-reflection layer is overlaid with a first thick photoresist. After having been fully exposed by a first photo mask, a predetermined exposure depth of the first thick photoresist is achieved by a second photo mask and dosage-controlled UV exposure. If the unexposed areas of the first thick photoresist are released during a development step, a single-layer microstructure is created. Inversely, a multi-layered microstructure can be obtained simply by repeating the process described above. After all layers are laminated on the substrate, all unexposed areas of the all thick photoresist layers are released and connected to each other during a development step.

    Abstract: New anti-reflective or fill compositions having improved flow properties are provided. The compositions comprise a styrene-allyl alcohol polymer and preferably at least one other polymer (e.g., cellulosic polymers) in addition to the styrene-allyl alcohol polymer. The inventive compositions can be used to protect contact or via holes from degradation during subsequent etching in the dual damascene process. The inventive compositions can also be applied to substrates (e.g., silicon wafers) to form anti-reflective coating layers having high etch rates which minimize or prevent reflection during subsequent photoresist exposure and developing.
