    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.

    摘要: A method for tone inversion for integrated circuit fabrication includes providing a substrate with an underlayer on top of the substrate; creating a first pattern, the first pattern being partially etched into a portion of the underlayer such that a remaining portion of the underlayer is protected and forms a second pattern, and such that the first pattern does not expose the substrate located underneath the underlayer; covering the first pattern with a layer of image reverse material (IRM); and etching the second pattern into the substrate. A structure for tone inversion for integrated circuit fabrication includes a substrate; a partially etched underlayer comprising a first pattern located over the substrate, the first pattern being partially etched into a portion of the underlayer such that a remaining portion of the underlayer is protected and forms a second pattern, and such that the first pattern does not expose the substrate located underneath the underlayer; and an image reversal material (IRM) layer located over the partially etched underlayer.

    摘要: A method of forming a trench is provided that includes providing a stack having a semiconductor layer or dielectric layer, a metal nitride layer, a leveling layer, and a first mask layer. First trenches are etched through the first mask layer and the leveling layer. The first mask layer is removed. A second mask layer is formed on the leveling layer. Second trenches are formed through the second mask layer, wherein the base of the second trenches do not extend through the metal nitride layer. The second mask layer is removed. Exposed portions of the metal nitride layer are etched selectively to the semiconductor layer and remaining portions of the leveling layer to extend the first trenches and the second trenches into contact with an upper surface of the semiconductor layer.

    摘要: An integrated circuit is formed with structures spaced more closely together than a transverse dimension of such structures, such as for making contacts to electronic elements formed at minimum lithographically resolvable dimensions by dark field split pitch techniques. Acceptable overlay accuracy and process efficiency and throughput for the split pitch process that requires etching of a hard mark for each of a plurality of sequentially applied and patterned resist layers is supported by performing the etching of the hard mask entirely within a lithography track through using an acid sensitive hard mark material and an acidic overcoat which contacts areas of the hard mask through patterned apertures in the resist. The contacted areas of the hard mask are activated for development by baking of the acidic overcoat.

    摘要: A self assembly step for the manufacture of an electronic component comprising, e.g., a semiconductor chip or semiconductor array or wafer comprises forming a block copolymer film placed on a random copolymer film substrate operatively associated with the electronic component and the block copolymer film wherein the surface energy of the random copolymer film is tailored by use of a photolithographic or chemical process prior to the self assembly step. By prior deterministic control over regional surface properties of the random copolymer film, domains of the block copolymer film form only in predefined areas. This approach offers simplified processing and a precise control of regions where domain formation occurs. Selective removal of some of the domains allows for further processing of the electronic component.
