摘要： Example embodiments relate to an apparatus and method for inspecting a substrate defect. The substrate defect inspecting apparatus includes a substrate, a light source emitting an infrared beam to the substrate, a detector detecting the infrared beam reflected from the substrate, and a defect analyzer receiving first information and second information from the detector and analyzing defects existing in the substrate. According to at least one example embodiment, the second information is acquired during a later process than the first information.

摘要： A method for inspection of defects on a substrate includes positioning a probe of a scanning probe microscopy (SPM) over and spaced apart from a substrate, includes scanning the substrate by changing a relative position of the probe with respect to the substrate on a plane spaced apart from and parallel to the substrate, and includes measuring a value of an induced current generated via the probe in at least two different regions of the substrate. The value of the induced current is variable according to at least a shape and a material of the substrate. The method further includes determining whether a defect exists by comparing the values of the induced currents measured in the at least two different regions of the substrate.
