    摘要: A mask (50′) with linewidth compensation and a method of making same. The mask provides for optimized imaging of isolated patterns (64) and nested patterns (70) present on the same mask. The compensated mask is formed from an uncompensated mask (50) and comprises an upper surface (56) upon which the isolated and nested patterns are formed. The isolated pattern comprises a first segment (76) having first sidewalls (76S). The nested pattern comprises second segments (72) proximate each other and having second sidewalls (72S). A partial conformal layer (86) covers the first segment and has feet (90) outwardly extending a distance d from the first sidewalls along the upper surface. The feet are preferably of a thickness that partially transmits exposure light.

    摘要: The present invention provides a method of forming nested and isolated images in a photosensitive resist. In the disclosed method, the entire surface of the photosensitive resist or selected regions thereof is exposed to a first mask having a set of nested, i.e. repeating pattern or grid images thereon, and then exposed to a second mask in order to remove unwanted portions of the nested image, so as to provide regions of nested and regions of isolated images in said photosensitive resist. The method may also be used to form regions having images in proximity to one another and regions having isolated images by exposing the entire surface of the photosensitive resist to a first mask having repeating patterns, and then removing entire or portions of the repeating patterns by exposure of the photosensitive resist with a second mask.

    摘要: A method is provided for patterning a substrate. In such method a first mask, for example, a front-end-of-line (“FEOL”) mask is fabricated, the first mask including a plurality of first features such as FEOL features which are usable to pattern regular elements and redundancy elements of a substrate such as a microelectronic substrate and/or a micro-electromechanical substrate. The first mask is tested, i.e., inspected for defects in the features. Thereafter, a second sequentially used mask, for example, a back-end-of-line (“BEOL”) mask is fabricated which includes a plurality of second features, e.g., BEOL features, such features being usable to pattern a plurality of interconnections between individual ones of the regular elements and between the regular elements and the redundancy elements. The regular elements and the redundancy elements are patterned using the first mask and the interconnections between them are patterned using the second mask. As a result, the interconnections are patterned in a way that corrects for the detected defects in the first mask.

    摘要: A method of implementing a new reticle for manufacturing semiconductors on a wafer which involves performing measurements on the reticle and assigning an initial exposure dose by using a predetermined algorithm. The exposure control system utilizes reticle CD data for automatically calculating reticle exposure offset values, i.e. reticle factors. A correlation of reticle size deviations to calculated reticle factors is used to derive a reticle factor for the new reticle. The derived reticle factor is then used to predict an initial exposure condition for the new reticle which is applied to the lithography tool for achieving a wafer design dimension.
