  • Patent number: 9946165
    Abstract: In a lithographic process, product units such as semiconductor wafers are subjected to lithographic patterning operations and chemical and physical processing operations. Alignment data or other measurements are made at stages during the performance of the process to obtain object data representing positional deviation or other parameters measured at points spatially distributed across each unit. This object data is used to obtain diagnostic information by performing a multivariate analysis to decompose a set of vectors representing the units in said multidimensional space into one or more component vectors. Diagnostic information about the industrial process is extracted using the component vectors. The performance of the industrial process for subsequent product units can be controlled based on the extracted diagnostic information.

  • Patent number: 9946167
    Abstract: Methods are disclosed for measuring target structures formed by a lithographic process on a substrate. A grating structure within the target is smaller than an illumination spot and field of view of a measurement optical system. The optical system has a first branch leading to a pupil plane imaging sensor and a second branch leading to a substrate plane imaging sensor. A spatial light modulator is arranged in an intermediate pupil plane of the second branch of the optical system. The SLM imparts a programmable pattern of attenuation that may be used to correct for asymmetries between the first and second modes of illumination or imaging. By use of specific target designs and machine-learning processes, the attenuation patterns may also be programmed to act as filter functions, enhancing sensitivity to specific parameters of interest, such as focus.

  • Patent number: 9946201
    Abstract: An image-forming apparatus contains a control portion that controls a cooling operation of the fixing portion. The control portion sets an image confirmable position in which an image formed on a long sheet is confirmable. When a print job on the long sheet finishes, the control portion starts the cooling operation of the fixing portion and controls the conveying portion to convey the long sheet until a rear end of a final image fixed by a fixing portion reaches the image confirmable position and finishes the cooling operation of the fixing portion until the rear end of the image fixed by the fixing portion reaches the image confirmable position. The control portion also sets the image confirmable position to be at an outermost circumference of rolled paper reeled by a reeling apparatus.

  • Patent number: 9946206
    Abstract: An image defect predictive diagnostic apparatus includes an acquisition unit and a notification unit. The acquisition unit acquires first characteristic values and second characteristic values from an image forming apparatus that forms an image by using an electrophotographic process. The first characteristic values include at least one of (i) toner concentrations and (ii) developing potentials. The first characteristic values have an influence on developability. The second characteristic values are different from the first characteristic values. The notification unit predicts occurrence of a dot image which has no relationship with the image by using the first characteristic values and the second characteristic values which are acquired by the acquisition unit, and that makes notification.
