  • Patent number: 8865599
    Abstract: Planarization methods and microelectronic structures formed therefrom are disclosed. The methods and structures use planarization materials comprising fluorinated compounds or acetoacetylated compounds. The materials are self-leveling and achieve planarization over topography without the use of etching, contact planarization, chemical mechanical polishing, or other conventional planarization techniques.

  • Patent number: 7998318
    Abstract: A via and contact hole fill composition and method for using the composition in the dual damascene production of circuits is provided. Broadly, the fill compositions include a quantity of solid components including a polymer binder and a solvent system for the solid components. The boiling point of the solvent system is less than the cross-linking temperature of the composition. Preferred solvents for use in the solvent system include those selected from the group consisting of alcohols, ethers, glycol ethers, amides, ketones, and mixtures thereof. Preferred polymer binders are those having an aliphatic backbone and a molecular weight of less than about 80,000, with polyesters being particularly preferred.

  • Patent number: 7132216
    Abstract: An improved light attenuating compound for use in the production of microdevices is provided. Broadly, the light attenuating compound is non-aromatic and can be directly incorporated (either physically or chemically) into photolithographic compositions such as bottom anti-reflective coatings (BARC) and contact or via hole fill materials. The preferred non-aromatic compounds of the invention are conjugated aliphatic and alicyclic compounds which greatly enhance the plasma etch rate of the composition. Furthermore, the light attenuating compounds are useful for absorbing light at shorter wavelengths. In one embodiment, the inventive compounds can be polymerized so as to serve as both the polymer binder of the composition as well as the light absorbing constituent.

  • Patent number: 6962769
    Abstract: Anti-reflective compositions and methods of using those compositions to form circuits are provided. The compositions comprise a polymer dissolved or dispersed in a solvent system. In one embodiment, the compositions comprise less than about 0.3% by weight of a strong acid. In another embodiment, the weight ratio of strong acid to weak acid in the composition is from about 0:100 to about 25:75. Examples of preferred weak acid compounds include phenolic compounds (e.g., Bisphenol S, Bisphenol A, ?-cyano-4-hydroxycinnamic acid), carboxylic acids (e.g., acetic acid), phosphoric acid, and cyano compounds. The polymer and other ingredients are preferably physically mixed in a solvent system. The resulting compositions are spin bowl compatible (i.e., they do not crosslink prior to the bake stages of the microlithographic processes or during storage at room temperature).

  • Patent number: 6670425
    Abstract: Anti-reflective compositions and methods of using those compositions with low dielectric constant materials are provided. In one embodiment, the compositions include polymers comprising recurring monomers having unreacted epoxide groups. In another embodiment, the polymers further comprise recurring monomers comprising epoxide rings reacted with a light attenuating compound so as to open the ring. The compositions can be applied to dielectric layers so as to minimize or prevent reflection during the dual damascene process while simultaneously blocking via or photoresist poisoning which commonly occurs when organic anti-reflective coatings are applied to low dielectric constant layers.
