Patent number: 11996842Abstract: An integrated circuit includes a flip-flop circuit and a gating circuit. The flip-flop circuit is arranged to receive an input data for generating a master signal during a writing mode according to a first clock signal and a second clock signal, and to output an output data according to the first clock signal and the second clock signal during a storing mode. The gating circuit is arranged for generating the first clock signal and the second clock signal according to the master signal and an input clock signal. When the input clock signal is at a signal level, the first clock signal and the second clock signal are at different logic levels. When the input clock signal is at another signal level, the first clock signal and the second clock signal are at a same logic level determined according to a signal level of the master signal.Type: GrantFiled: November 17, 2022Date of Patent: May 28, 2024Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.Inventors: Greg Gruber, Chi-Lin Liu, Ming-Chang Kuo, Lee-Chung Lu, Shang-Chih Hsieh

Patent number: 11989424Abstract: The invention discloses a digital signature system. The digital signature system comprises an electronic device and a data storage device. The electronic device generates a specific data by executing a specific operation, and calculates the specific data via a hash algorithm to generate a hash data. The data storage device comprises a controller, a plurality of flash memories, and a data transmission interface. The electronic device transmits the hash data to the data storage device via the transmission interface. The controller comprises a firmware. The firmware reads an unclonable function, and generates a private key according to the unclonable function, and encrypts the hash data by the private key to obtain a digital signature. The data storage device transmits the digital signature to the electronic device via the transmission interface.Type: GrantFiled: October 18, 2021Date of Patent: May 21, 2024Assignee: INNODISK CORPORATIONInventors: Ming-Sheng Chen, Chin-Chung Kuo

Publication number: 20240128122Abstract: Semiconductor package includes substrate, first barrier layer, second barrier layer, routing via, first routing pattern, second routing pattern, semiconductor die. Substrate has through hole with tapered profile, wider at frontside surface than at backside surface of substrate. First barrier layer extends on backside surface. Second barrier layer extends along sidewalls of through hole and on frontside surface. Routing via fills through hole and is separated from sidewalls of through hole by at least second barrier layer. First routing pattern extends over first barrier layer on backside surface and over routing via. First routing pattern is electrically connected to end of routing via and has protrusion protruding towards end of routing via in correspondence of through hole. Second routing pattern extends over second barrier layer on frontside surface. Second routing pattern directly contacts another end of routing via. Semiconductor die is electrically connected to routing via by first routing pattern.Type: ApplicationFiled: December 25, 2023Publication date: April 18, 2024Applicant: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Wei-Chung Chang, Ming-Che Ho, Hung-Jui Kuo

Patent number: 8381964Abstract: A Sn—Ag bonding and a method thereof are revealed. By means of a bonding layer formed by tin and silver between wafers, the stress released by diffusion and bonding between tin(Sn) and silver(Ag) is larger than the stress released by diffusion and bonding of conventional gold-silver bonding. Moreover, a Sn—Ag bonding method of the present invention forms Sn—Ag bonding at low temperature and releases more stress so as to reduce thermal stress generated during wafer bonding effectively. And after wafer bonding, the high temperature processes can be performed.Type: GrantFiled: April 16, 2012Date of Patent: February 26, 2013Assignee: National Central UniversityInventors: Cheng-Yi Liu, Ming-Chung Kuo
