  • Patent number: 11100272
    Abstract: A method includes obtaining a layout of a circuit pattern implemented on a semiconductor wafer, and identifying one or more polygons in the layout based on a length criteria. One or more measurement gauges are placed on the identified polygons to thereby obtain measured polygons. A scanning electron microscope (SEM) image of the circuit pattern is obtained. The SEM image is aligned with the layout including the measured polygons. A critical dimension of one or more objects in the SEM image is measured. The one or more objects correspond to the one or more polygons. Based on the measured critical dimension, it is determined whether the circuit pattern is acceptable.

  • Publication number: 20210208505
    Abstract: An extreme ultraviolet lithography method is disclosed. In an example, the EUVL method includes forming a resist layer on a substrate; performing a first exposure process to image a first pattern of a first sub-region of a first mask to the resist layer; performing a second exposure process to image a second pattern of a second sub-region of the first mask to the resist layer; and performing a third exposure process to image a third pattern of a first sub-region of a second mask to the resist layer. The second and third patterns are identical to the first pattern. The first, second and third exposure processes collectively form a latent image of the first pattern on the resist layer.

    Abstract: The present disclosure provides one embodiment of an IC method. First pattern densities (PDs) of a plurality of templates of an IC design layout are received. Then a high PD outlier template and a low PD outlier template from the plurality of templates are identified. The high PD outlier template is split into multiple subsets of template and each subset of template carries a portion of PD of the high PD outlier template. A PD uniformity (PDU) optimization is performed to the low PD outlier template and multiple individual exposure processes are applied by using respective subset of templates.

  • Patent number: 10008171
    Abstract: A gate driving circuit is provided. The gate driving circuit includes multistage driving modules, where an Nth stage driving module includes a setting circuit, a first driving circuit, an isolating switch circuit, a second driving circuit and an anti-noise circuit. The setting circuit generates a first precharge signal according to a gate driving signal of an (N?2)th scan line or a start signal. The isolating switch circuit coupled between the first driving circuit and the second driving circuit provides a second precharge signal, so as to effectively avoid a flickering problem of a display image caused by a surge of the gate driving signal due to a coupling effect of a parasitic capacitance of the transistor and a bootstrap capacitor, and meanwhile the bootstrap capacitor is not used, so as to effectively reduce a bezel area.
