Claim One:
1. A defect analysis assistance device comprising: a processor; and memory storing one or more programs for execution by the processor, the one or more programs including instructions for: analyzing a defect of a target to be inspected; dividing analysis target images among observation images of sample patterns of the target to be inspected with respect to each of a plurality of layers according to a manufacturing process by an image analysis or an operator's specification; generating a plurality of layer division images; calculating a degree of matching between each of the layer division images and each design layer of the design layout data; and specifying a design layer with a highest degree of matching of the each design layer as a design layer corresponding to the layer division image, wherein analysis target images are sampled from the observation images based on an occurrence rate of a manufacturing pattern for each hierarchy occupied in the images to be observed.
