  • Patent number: 8855401
    Abstract: A method for measuring a dimension of a device includes receiving an image of a portion of the device, receiving a first offset value and a second offset value, processing the image to define a least one graph of a line of pixels, the at least one graph including the brightness level of each pixel in a line of pixels, identifying a location of a first peak and a second peak in the graph, defining a first exclusion area boundary, defining a second exclusion area boundary, setting the brightness level of the pixels between the first exclusion area boundary and the second exclusion area boundary to zero, identifying a first portion of the feature of interest and a second portion of the feature of interest, and measuring a distance between the first portion of the feature of interest and the second portion of the feature of interest.

  • Patent number: 7716009
    Abstract: A method of preparing recipes of operating a metrology tool, wherein each recipe includes a set of instructions for measuring at least one dimension in a microelectronic feature. There is provided a desired recipe having instructions for measuring one or more desired dimensions, the desired recipe or portion thereof including a summary of parameters relating to metrology tool function with respect to the microelectronic feature dimension to be measured. The method includes comparing the instructions in the desired recipe with the instructions in a database, identifying differences between the instructions in the desired recipe and the instructions in the database, modifying the instructions in the desired recipe to conform to the instructions in the database, verifying the desired recipe prior to using the modified desired recipe by the metrology tool, and using the desired recipe to execute a microelectronic feature measurement on the metrology tool.

  • Publication number: 20080065696
    Abstract: A method of preparing recipes for operating a metrology tool, wherein each recipe comprises a set of instructions for measuring at least one dimension in a microelectronic feature. A database includes a plurality of known instructions with best known methods for measuring different dimensions in a microelectronic feature by creating a summary of a recipes used by the metrology tool, and adding to the summary categorization attributes to identify the recipe summary for retrieval from the database. There is provided a desired recipe having instructions for measuring one or more desired dimensions, the desired recipe or portion thereof including a summary of parameters relating to metrology tool function with respect to the microelectronic feature dimension to be measured.
