摘要： An inspection method includes photographing a measurement target to acquire image data for each pixel of the measurement target, acquiring height data for each pixel of the measurement target, acquiring visibility data for each pixel of the measurement target, multiplying the acquired image data by at least one of the height data and the visibility data for each pixel to produce a result value, and setting a terminal area by using the produced result value. Thus, the terminal area may be accurately determined.

摘要： In order to inspect a board, a measurement area is set on a board, and reference data and measurement data of the measurement area are acquired. Then, a conversion condition is established for the measurement area, and a conversion relation is acquired according to a distortion degree between reference data and measurement data. Thereafter, validity of the conversion relation is verified by using at least one of verifying that a comparison feature object satisfies the conversion relation, verifying that a verification feature object selected from feature objects satisfies the conversion relation and verifying that a pad formed on the board satisfies the conversion relation. Then, the conversion condition is confirmed, and an inspection area for inspecting a measurement target is set according to the confirmed conversion condition. Thus, an inspection area may be correctly set so that distortion is compensated for.

摘要： In order to inspect a board, firstly, a measurement area is set on a board, and reference data and measurement data of the measurement area are acquired. Then, a plurality of feature blocks is established by a block unit so as to include a predetermined shape in the measurement area, and a merged block is established by merging feature blocks overlapped in the feature blocks. Thereafter, a distortion degree is acquired by comparing reference data and measurement data corresponding to a feature block except for the merged block and/or the merged block, and the distortion degree is compensated for, to set an inspection area in the target measurement area. Thus, an inspection area, in which distortion is compensated for, may be correctly set.

摘要： A method of inspecting a substrate is disclosed. The method is performed by a substrate-inspecting apparatus having at least one projecting module projecting a patterned light onto a substrate fixed on a stage and an inspecting module with a camera capturing an image, and inspecting a plurality of inspection regions of the substrate step by step. The method comprises, setting an inspection order of the inspecting regions according to a lengthwise direction of the substrate, estimating height displacement of a target inspection region by using a tendency information regarding at least one previous inspection region that is already inspected, adjusting height of the inspecting module by using the estimated height displacement of the target inspection region, and inspecting the target inspection region by using the inspecting module of which height is adjusted. Therefore, inspection time is reduced.
