Publication number: 20240143791Abstract: 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.Type: ApplicationFiled: May 30, 2023Publication date: May 2, 2024Applicant: Silicon Motion, Inc.Inventors: Wun-Jhe WU, Po-Hung CHEN, Chiao-Wen CHENG, Jiun-Hung YU, Chih-Wei LIU

Publication number: 20100224217Abstract: A semiconductor cleaning method and apparatus and a controlling method of semiconductor cleaning are disclosed. The developing method includes the following steps. A developing solution is applied onto a wafer having a photoresist layer. Next, the wafer is rotated to scatter the developing solution over the photoresist layer. Then, a nozzle upon the center of the wafer ejects a non-reactive liquid onto the photoresist layer for a time period. Next, the nozzle is moved in a radial direction of the wafer to at least one next location and then ejects the liquid onto the photoresist layer for at least one next time period. The wafer is then rinsed until the developing solution and the unnecessary photoresist dissolved in the developing solution are washed away and a patterned photoresist layer is revealed.Type: ApplicationFiled: March 6, 2009Publication date: September 9, 2010Applicant: MACRONIX INTERNATIONAL CO., LTD.Inventors: Cheng-Hui Chen, Chun-Chieh Wang, Po-Wei Yu
