    Abstract: Systems and methods for detecting defects on a wafer are provided. One method includes generating output for a wafer by scanning the wafer with an inspection system using first and second optical states of the inspection system. The first and second optical states are defined by different values for at least one optical parameter of the inspection system. The method also includes generating first image data for the wafer using the output generated using the first optical state and second image data for the wafer using the output generated using the second optical state. In addition, the method includes combining the first image data and the second image data corresponding to substantially the same locations on the wafer thereby creating additional image data for the wafer. The method further includes detecting defects on the wafer using the additional image data.

    Abstract: An inspection system for detecting anomalies on a substrate. The inspection system has a sensor array for generating image data. A first high speed network is coupled to the sensor array and receives and communicates the image data. An array of process nodes is coupled to the first high speed network, and receives and processes the image data to produce anomaly reports. Each process node has an interface card coupled to the first high speed network, that receives the image data from the first high speed network and formats the image data according to a high speed interface bus protocol. The interface card sets a register indicating whether a predetermined amount of image data has been stored in a memory, and the process node reads the register to determine whether the predetermined amount of image data has been stored in the memory, and initiates image processing when the register indicates that the predetermined amount of image data has been stored in the memory.

    Abstract: Computer-implemented methods, carrier media, and systems for determining sizes of defects detected on a wafer are provided. One computer-implemented method includes separating the defects into groups based on output acquired for the defects by multiple channels of an inspection system used to detect the defects on the wafer. The method also includes separating the defects in one or more of the groups into subgroups based on the output acquired for the defects by one or more of the multiple channels. In addition, the method includes determining the sizes of one or more of the defects in one or more of the subgroups separately based on the output acquired for the defects by only one of the multiple channels and a calibration parameter. The calibration parameter is different for each of the subgroups and is acquired by using another system to measure actual sizes of defects detected on other wafers.

    Abstract: Methods for identifying array areas in dies formed on a wafer and methods for setting up such methods are provided. One method for identifying array areas in dies formed on a wafer includes comparing an array pattern in a template image acquired in one of the array areas to a search area image acquired for the wafer. The method also includes determining areas in the search area image in which a pattern is formed that substantially matches the array pattern in the template image based on results of the comparing step. In addition, the method includes identifying the array areas in the dies formed on the wafer based on results of the determining step.

    Abstract: Computer-implemented methods, carrier media, and systems for selecting polarization settings for an inspection system for inspection of a layer of a wafer are provided. One method includes detecting a population of defects on the layer of the wafer using results of each of two or more scans of the wafer performed with different combinations of polarization settings of the inspection system for illumination and collection of light scattered from the wafer. The method also includes identifying a subpopulation of the defects for each of the different combinations, each of which includes the defects that are common to at least two of the different combinations, and determining a characteristic of a measure of signal-to-noise for each of the subpopulations. The method further includes selecting the polarization settings for the illumination and the collection to be used for the inspection corresponding to the subpopulation having the best value for the characteristic.
