Abstract: In a method of classifying defects of a pattern, SEM images having different colors on the same pattern are aligned and merged. The defects of the pattern are located by color difference in the merged SEM image. The defects of the pattern are firstly located at the location of the defects. A design in which a layout of the pattern is drawn, and the merged SEM image are aligned. The defects of the pattern are secondly classified by comparing the layout of the pattern drawn in the design and the merged SEM image. A type of the defects of the pattern is determined by combination of the first and second classifications of the defects of the pattern.

Abstract: An electronic device includes a plurality of coils, power conversion circuits, demodulation switches, and a processor. The power conversion circuits convert DC power into AC power, and output the AC power to the plurality of coils, respectively. The demodulation switches selectively connect the plurality of coils to ground. The processor selects at least one coil from among the plurality of coils, and controls an on/off state of the demodulation switches to connect or disconnect at least one remaining coil except for the selected at least one coil among the plurality of coils to the ground. The processor controls the power conversion circuits to output the AC power to the selected at least one coil and demodulates a signal of the selected at least one coil to identify information from an external electronic device disposed adjacent to a selected at least one coil based on the demodulation.
