  • Patent number: 8728713
    Abstract: A method for producing a measurement structure for measuring alignment of patterns formed in one or more layers of patternable material uses multiple exposure tools having different resolution limits and maximum expose field sizes. The measurement structure includes multiple complementary and coincident parts. An abutting field pattern is exposed and stitched in a layer of patternable material using a first exposure tool and a first mask. The abutting field pattern includes a first portion of the multiple complementary parts. A periphery pattern is exposed in the same layer or in a different layer of patternable material using a second exposure tool and a second mask. The periphery pattern includes a second portion of the multiple complementary parts. A maximum expose field of the first exposure tool is smaller than the maximum expose field of the second exposure tool.

  • Patent number: 8728722
    Abstract: A method for producing a device in one or more layers of patternable material disposed over a substrate uses multiple exposure tools having different resolution limits and maximum expose field sizes. An abutting field pattern is exposed and stitched in one layer of patternable material using one exposure tool and a first mask. A periphery pattern is then exposed in the same layer or in a different layer of patternable material using a second exposure tool and a second mask. The maximum expose field of the first exposure tool is smaller than a size of the device while the maximum expose field of the second exposure tool is at least as large as, or larger, the size of the device so that the combination of the stitched abutting field pattern and the periphery pattern forms a complete pattern in the patternable material.

  • Patent number: 8415175
    Abstract: A semiconductor wafer includes multiple dies and a die identification region adjacent to or on each die. The die identification region can include a wafer indicator and a pattern of die locations representing die locations on the wafer. A die identification marker is provided in each pattern of die locations in the die identification region specifying a location of a respective die on the wafer.

  • Publication number: 20080138986
    Abstract: A method for forming a patterned target layer over a substrate uses a blanket target layer located over the substrate and a patterned mask layer located over the blanket target layer At least one mask layer pattern wit the patterned mask layer is treated with a charged particle beam to provide a dimensionally changed mask layer pattern within a dimensionally changed mask. The dimensionally changed mask is used as an etch mask when etching the blanket target layer to form the patterned target layer.

  • Patent number: 6944578
    Abstract: A method uses three dimensional feature metrology for implementation of critical image control and feedback of lithographic focus and x/y tilt. The method is for measuring 3 dimensional profile changes in a photo sensitive film and feeding back compensatory exposure tool focus corrections to maintain a stable lithographic process. The measured focus change from the optimal tool focus offset is monitored directly on the critical product images for both contact hole and line images. Z Focus corrections and x/y tilt corrections are fed back independently of dose to maintain critical dimension (CD) control. Additionally, the method can be used to diagnose problems with the focusing system by measuring the relationship between line edge width and barometric pressure.
