An inspection apparatus includes a light source device providing incident light to a substrate, an objective lens receiving reflection light reflected from the substrate, a light splitting device disposed over the objective lens, first and second optical sensors disposed at both sides of the light splitting device, respectively, and first and second spatial filters disposed between the first optical sensor and the substrate and between the second optical sensor and the substrate, respectively. The first and second spatial filters transmit the reflection light in different forms from each other.

Inspection apparatus, semiconductor device manufacturing system including the same, and method of manufacturing a semiconductor device using the same

An optical inspection apparatus includes an inspection target unit on which an inspection target is loaded, an illumination optical unit configured to irradiate incident light to the inspection target, an objective lens unit disposed between the illumination optical unit and the inspection target unit, a detection optical unit configured to receive reflective light reflected from the inspection target to thereby detect a presence or absence of a defect on the inspection target, and a control unit configured to control the illumination optical unit and the detection optical unit. The illumination optical unit includes a light source part configured to irradiate the incident light, and a spatial filter array configured to modify a transmission region of the incident light irradiated from the light source part. The spatial filter array includes a spatial filter part, and a filter movement part configured to move the spatial filter part.

Optical inspection apparatus, a method of inspecting a substrate, and a method of treating a substrate

An encoding method comprises receiving a plurality of video frames including first and third reference frames (F, F) and a target frame (F); generating a temporary frame based on assumed constant-velocity motion between the first and third reference frames (F, F); comparing the temporary frame target frame to detect nonlinear motion (errors in the temporary frame) between the first and third reference frames and to produce motion vector information between the target frame and at least one of the reference frames according to the comparison; and encoding the reference frames and the motion vector information.
