    摘要: The present disclosure relates to a lithographic tool arrangement for semiconductor workpiece processing. The lithographic tool arrangement groups lithographic tools into clusters, and selectively transfers a semiconductor workpiece between a plurality of lithographic tools of a first type in a first cluster to a plurality of lithographic tools of a second type in a second cluster. The selective transfer is achieved though a transfer assembly, which is coupled to a defect scan tool that identifies defects generated in the lithographic tool of the first type. The disclosed lithographic tool arrangement also utilizes shared structural elements such as a housing assembly, and shared functional elements such as gases and chemicals. The lithographic tool arrangement may consist of baking, coating, exposure, and development units configured to provide a modularization of these various components in order to optimize throughput and efficiency for a given lithographic fabrication process.

    摘要: A method of manufacturing a photomask is described. The graphic data of the photomask are provided, and than an optical proximity correction is performed to the graphic data. A process rule check is then performed to the graphic data with the optical proximity correction. When at least one failed pattern not passing the process rule check is found in the graphic data, a repair procedure is performed only to the failed pattern so that the failed pattern can pass the process rule check. The patterns of the photomask are then formed according to the corrected and repaired graphic data.

    摘要: A dual damascene process involves forming a first passivation layer, a first dielectric layer and a second passivation layer on a substrate of a semiconductor wafer. A first lithography and etching process is performed to form at least one via hole in the second passivation layer and the first dielectric layer. Thereafter, a second dielectric layer and a third passivation layer are formed on the surface of the semiconductor wafer followed by performing a second lithography and etching process to form at least one trench in the third passivation layer and the second dielectric layer. The trench and the via hole together construct a dual damascene structure. Finally, a barrier layer and a metal layer are formed on the surface of the semiconductor wafer, and a chemical-mechanical-polishing (CMP) process is performed to complete the dual damascene process.

    摘要: The present invention fabricates a dual damascene structure. A passivation layer, a first dielectric layer, a second passivation layer, a second dielectric layer, a third passivation layer and a third dielectric layer are formed on the surface of the semiconductor wafer followed by etching the third dielectric layer to form a pattern of an upper trench of the dual damascene structure. Then the third passivation layer and the second dielectric layer are etched down to the surface of the second passivation layer so as to form a pattern of a via hole of the dual damascene structure. Thereafter, the third passivation layer and the second passivation layer not covered by the third dielectric layer and the second dielectric layer are removed. The third dielectric layer and the second passivation layer are used as hard masks to remove the second dielectric layer and the first dielectric layer until the surface of the first passivation layer. Finally, the second passivation layer and the first passivation layer not covered by the second dielectric layer and the first dielectric layer are removed to the surface of the conductive layer so completing the process of fabricating the dual damascene structure.
