Publication number: 20240144467Abstract: 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.Type: ApplicationFiled: January 8, 2024Publication date: May 2, 2024Applicant: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Chien-Huei Chen, Pei-Chao Su, Xiaomeng Chen, Chan-Ming Chang, Shih-Yung Chen, Hung-Yi Chung, Kuang-Shing Chen, Li-Jou Lee, Yung-Cheng Lin, Wei-Chen Wu, Shih-Chang Wang, Chien-An Lin

Publication number: 20050027966Abstract: A digital signal processor (DSP) code download device is disclosed. The device is used for downloading a DSP code comprising a Servo system control code from a re-programmable memory and then storing the DSP code in a memory. The DSP code download device includes a re-programmable memory reader for downloading the DSP code from the re-programmable memory, a download procedure controller coupled to the re-programmable memory reader and a memory accessor coupled to the download procedure controller for accessing the memory.

Patent number: 6581083Abstract: A means and a method applied in syndrome generation in the Video/Audio processing system is disclosed. The syndromes thereof are effectively and rapidly generated simply using shift register and an exclusive or adder by a recursive operation. For the code words having a number of bytes, the syndromes can be generated by repeating exclusive or (XOR) operation between a shift bit and the above-mentioned bytes, without the extra step of table-matching, saving large memory capacity, greatly reducing the operation cycle and completing the operation rapidly.Type: GrantFiled: November 8, 1999Date of Patent: June 17, 2003Assignee: Via Technologies, Inc.Inventors: Wei-Ming Su, Shin Yung Chen, Pei-Jei Hu

Patent number: 6499082Abstract: A method for transferring data from a large capacity data storage device to a host machine. The method requires the attachment of a plurality of SRAM memory blocks to an optical disk reader. Each SRAM memory block is used as temporary storage area got a sector of data so that data can be proofread one sector at a time. As soon as the entire sector is checked and corrected, the error-free data is transferred to an external DRAM memory. Thereafter, correct data can be read from the DRAM by the host machine at any time. The internal SRAM memory serves as a buffer holding sectors of data so that error detection and error correction of individual sector can be carried out. Additionally, the external DRAM memory serves as a buffer holding the correct data for the host machine.Type: GrantFiled: September 10, 1999Date of Patent: December 24, 2002Assignee: Via Technologies, Inc.Inventors: Kun-Long Lin, Wei-Ming Su, Pei-Jei Hu

Patent number: 6457035Abstract: A table matching method for multiplication of elements in Galois Field. First, a table of the byte value in Galois Field and the corresponding exponent is formed in the hardware. To perform the multiplication between two elements in the Galois Field, the corresponding exponents of the two elements are found out in advance. The two exponents are then added up to obtain a sum. Then, by using the table, a corresponding byte value of the sum can be obtained. The byte value is the product of the two elements in the Galois Field.Type: GrantFiled: November 8, 1999Date of Patent: September 24, 2002Assignee: Via Technologies, Inc.Inventors: Wei-Ming Su, Banyan Shin Yung Chen, Yi-Lin Lai
