    摘要: A reticle includes a first pattern formed in a first die flash region of the reticle and a second pattern different than the first pattern formed in a second die flash region of the reticle. A method for patterning a wafer having a plurality of die regions defined thereon includes exposing a first die region using a first pattern formed on a reticle during a first exposure, repositioning the reticle, and exposing the first die region using a second pattern formed on the reticle during a second exposure.

    摘要: A method includes collecting optical data from an unpatterned region including a first process layer. At least one optical parameter of the first process layer is determined based on the optical data associated with the unpatterned region. Optical data is collected from a patterned region including a second process layer. At least one characteristic of the patterned region is determined based on the optical data associated with the patterned region and the at least one optical parameter.

    摘要: A method includes specifying a plurality of optical proximity correction metrology sites on a wafer. Metrology data is collected from at least a subset of the metrology sites. Data values are predicted for the subset of the metrology sites using an optical proximity correction design model. The collected metrology data is compared to the predicted data values to generate an optical proximity correction metric. A problem condition associated with the optical proximity correction design model is identified based on the optical proximity correction metric.

    摘要: The claimed subject matter provides a system and/or a method that facilitates utilizing a resolution enhancement for a circuit feature. A scanning electron microscope component (104, 204, 304, 404) can provide at least one two-dimensional image of the circuit feature. An image analysis engine (106, 206, 306, 406) can analyze the two-dimensional image. An advanced process control (APC) engine (108, 208, 308, 408) can generate at least one instruction for at least one of a feed forward control and a feedback control and a process component (102, 202, 302, 402) can utilize the at least one instruction to minimize an error.
