    摘要: Electric fields may be advantageously used in various steps of photolithographic processes. For example, prior to the pre-exposure bake, photoresists that have been spun-on the wafer may be exposed to an electric field to orient aggregates or other components within the unexposed photoresist. By aligning these aggregates or other components with the electric field, line edge roughness may be reduced, for example in connection with 193 nanometer photoresist. Likewise, during exposure, electric fields may be applied through uniquely situated electrodes or using a radio frequency coil. In addition, electric fields may be applied at virtually any point in the photolithography process by depositing a conductive electrode, which is subsequently removed during development. Finally, electric fields may be applied during the developing process to improve line edge roughness.

    摘要: An embodiment of the present invention includes a technique to provide a highly absorptive resist. A resist is formed using a highly absorbing material. The resist is thinned to a pre-determined thickness used as an imaging layer. The efficiency of a photoactive acid generator (PAG) is improved to capture secondary electrons produced by an ionizing radiation in the resist.

    摘要: A thermally decomposable sacrificial material is deposited in a void or opening in a dielectric layer on a semiconductor substrate. The thermally decomposable sacrificial material may be removed without damaging or removing the dielectric layer. The thermally decomposable sacrificial material may be a combination of organic and inorganic materials, such as a hydrocarbon-siloxane polymer hybrid.

    摘要: An adhesion promoter to help reduce semiconductor process effects, such as undesired line edge roughness, insufficient lithographical resolution, and limited depth of focus problems associated with the removal of a photoresist layer. A photoactive adhesion promoter (PAG) is described which helps reduce these and other undesired effects associated with the removal of photoresist in a semiconductor manufacturing process.
