    Abstract: A wafer measurement system for measuring a measurable characteristic of a first measurement target formed on a wafer includes: a memory and a processor. The memory is configured to store an image of the wafer, multiple templates each including at least one line, and a measurement program. The processor is accessible to the memory and is configured to execute multiple modules included in the measurement program. The modules include: a template selection module configured to receive the templates and select a measurement template corresponding to a shape of the first measurement target; a template matching module configured to match the measurement template to the first measurement target; and a measurement module configured to measure the measurable characteristic of the first measurement target based on position information of the measurement template.

    Abstract: A system of analyzing a crystal defect includes an image processor, an image generator, and a comparator. The image processor processes a measured transmission electron microscope (TEM) image that is provided by capturing an image of a specimen having a crystal structure, to provide structural defect information of the specimen. The image generator provides a plurality of virtual TEM images corresponding to a plurality of three-dimensional structural defects of the crystal structure. The comparator compares the measured TEM image with the plurality of virtual TEM images using the structural defect information to determine a defect type of the measured TEM image.
