  • Publication number: 20240143791
    Abstract: The invention introduces an apparatus for detecting errors during data encryption. The apparatus includes a search circuitry and a substitution check circuitry. The key generation circuitry is arranged operably to convert a first value of one byte corresponding to a plaintext, an intermediate encryption result, or a round key into a second value of a K-bit according to an 8-to-K lookup table, where K is an integer ranging from 10 to 15 and the second value comprises (K minus 8) bits of a Hamming parity. The substitution check circuitry is arranged operably to employ check formulae corresponding to the 8-to-K lookup table to determine whether an error is occurred during a conversion of the first value of the one byte into the second value of the K-bit, and output an error signal when finding the error, where a total amount of the formulae is K minus 8.

    Abstract: A hot spot defect detecting method and a hot spot defect detecting system are provided. In the method, hot spots are extracted from a design of a semiconductor product to define a hot spot map comprising hot spot groups, wherein local patterns in a same context of the design yielding a same image content are defined as a same hot spot group. During runtime, defect images obtained by an inspection tool performing hot scans on a wafer manufactured with the design are acquired and the hot spot map is aligned to each defect image to locate the hot spot groups. The hot spot defects in each defect image are detected by dynamically mapping the hot spot groups located in each defect image to a plurality of threshold regions and respectively performing automatic thresholding on pixel values of the hot spots of each hot spot group in the corresponding threshold region.
