    摘要: Novel processes of applying a thin, uniform, conformal organic polymeric film by a wide variety of deposition processes into lithography pattern substrates are provided. The inventive processes result in shrinking of the gaps in the lithography pattern equally, thus producing a smaller dimension. The amount of pattern shrinkage is selectively controlled by controlling the deposition rate to provide the desired final structure dimension. A wide variety of organic films is used as materials for these films. The inventive methods are applicable to any patterning technique used in lithography to provide a reduction in pattern sizes. Examples of the applicable device levels include the production of gate layers, ion implantation of active device layers and substantive metal layers, dielectric patterning, interconnect processes produced by damascene, dual damascene, backend packaging layers, and devices requiring multiple layers deposited by electrodeposition, CVD or sputtering. The inventive methods are useful for providing highly conformal coatings on large surface substrates having super submicron (i.e., 0.15 μm or smaller) features. The process is environmentally friendly and relatively low cost compared to other options.

    摘要: The present invention is directed towards planarization materials that produce little or no volatile byproducts during the hardening process when used in contact planarization processes. The materials can be hardened by photo-irradiation or by heat during the planarization process, and they include one or more types of monomers, oligomers, or mixtures thereof, an optional cross-linker, and an optional organic reactive solvents. The solvent, if used, is chemically reacted with the monomers or oligomers and thus becomes part of the polymer matrix during the curing process. These materials can be used for damascene, dual damascene, bi-layer, and multi-layer applications, microelectromechanical system (MEMS), packaging, optical devices, photonics, optoelectronics, microelectronics, and sensor devices fabrication.

    摘要: An improved 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. In use, the fill composition is applied to the substrate surfaces forming the contact or via holes as well as to the substrate surfaces surrounding the holes, followed by heating to the composition reflow temperature so as to cause the composition to uniformly flow into and cover the hole-forming surfaces and substrate surfaces. The composition is then cured, and the remainder of the dual damascene process is carried out.

    摘要: The present invention is directed towards contact planarization methods that can be used to planarize substrate surfaces having a wide range of topographic feature densities for lithography applications. These processes use thermally curable, photo-curable, or thermoplastic materials to provide globally planarized surfaces over topographic substrate surfaces for lithography applications. Additional coating(s) with global planarity and uniform thickness can be obtained on the planarized surfaces. These inventive methods can be utilized with single-layer, bilayer, or multi-layer processing involving bottom anti-reflective coatings, photoresists, hardmasks, and other organic and inorganic polymers in an appropriate coating sequence as required by the particular application. More specifically, this invention produces globally planar surfaces for use in dual damascene and bilayer processes with greatly improved photolithography process latitude. The invention further provides globally planar surfaces to transfer patterns using imprint lithography, nano-imprint lithography, hot-embossing lithography and stamping pattern transfer techniques.
