  • Patent number: 7732340
    Abstract: A method for adjusting the lateral critical dimension (i.e., length and width) of a feature formed in a layer on a substrate using a dry etching process. One or more thin intermediate sub-layers are inserted in the layer within which the feature is to be formed. Once an intermediate sub-layer is reached during the etching process, an etch process is performed to correct and/or adjust the lateral critical dimensions before etching through the intermediate sub-layer and continuing the layer etch.

  • Patent number: 7723009
    Abstract: A mask having features formed by self-organizing material, such as diblock copolymers, is formed on a partially fabricated integrated circuit. Initially, a copolymer template, or seed layer, is formed on the surface of the partially fabricated integrated circuit. To form the seed layer, diblock copolymers, composed of two immiscible blocks, are deposited in the space between copolymer alignment guides. The copolymers are made to self-organize, with the guides guiding the self-organization and with each block aggregating with other blocks of the same type, thereby forming the seed layer. Next, additional, supplemental diblock copolymers are deposited over the seed layer. The copolymers in the seed layer guide self-organization of the supplemental copolymers, thereby vertically extending the pattern formed by the copolymers in the seed layer.

    Abstract: A stack of a second photoresist having a second photosensitivity and a first photoresist having a first photosensitivity, which is greater than second photosensitivity, is formed on a substrate. A first pattern is formed in the first photoresist by a first exposure and a first development, while the second photoresist underneath remains intact. A second pattern comprising an array of lines is formed in the second photoresist. An exposed portion of the second photoresist underneath a remaining portion of the first photoresist forms a narrow portion of a line pattern, while an exposed portion of the second photoresist outside the area of the remaining portions of the photoresist forms a wide portion of the line pattern. Each wide portion of the line pattern forms a bulge in the second pattern, which increases overlay tolerance between the second pattern and the pattern of conductive vias.
