    摘要: A new lithographic process comprises reducing the linewidth of an image while maintaining the lithographic process window, and using this process to fabricate pitch split structures comprising nm order (e.g., about 22 nm) node semiconductor devices. The process comprises applying a lithographic resist layer on a surface of a substrate and patterning and developing the lithographic resist layer to form a nm order node image having an initial line width. Overcoating the nm order node image with an acidic polymer produces an acidic polymer coated image. Heating the acidic polymer coated image gives a heat treated coating on the image, the heating being conducted at a temperature and for a time sufficient to reduce the initial linewidth to a subsequent narrowed linewidth. Developing the heated treated coating removes it from the image resulting in a free-standing trimmed lithographic feature on the substrate. Optionally repeating the foregoing steps further reduces the linewidth of the narrowed line. The invention also comprises a product produced by this process.

    摘要: A method for self-aligned gate patterning is disclosed. Two masks are used to process adjacent semiconductor components, such as an nFET and pFET that are separated by a shallow trench isolation region. The mask materials are chosen to facilitate selective etching. The second mask is applied while the first mask is still present, thereby causing the second mask to self align to the first mask. This avoids the undesirable formation of a stringer over the shallow trench isolation region, thereby improving the yield of a semiconductor manufacturing operation.

    摘要: Methods of multiple exposure in the fields of deep ultraviolet photolithography, next generation lithography, and semiconductor fabrication comprise a spin-castable methodology for enabling multiple patterning by completing a standard lithography process for the first exposure, followed by spin casting an etch selective overcoat layer, applying a second photoresist, and subsequent lithography. Utilizing the etch selectivity of each layer, provides a cost-effective, high resolution patterning technique. The invention comprises a number of double or multiple patterning techniques, some aimed at achieving resolution benefits, as well as others that achieve cost savings, or both resolution and cost savings. These techniques include, but are not limited to, pitch splitting techniques, pattern decomposition techniques, and dual damascene structures.
