Publication number: 20240178745Abstract: An alternating current control system includes a zero crossing detector, an alternating current solid state relay, a constant current driver, and a microcontroller connected to the zero crossing detector and the constant current driver. The zero crossing detector and the alternating current solid state relay are connected to an alternating current power source, a first control pin of the microcontroller receives a zero crossing detection signal outputted by the zero crossing detector, a second control pin of the microcontroller receives a switch state signal, and a third control pin of the microcontroller is connected to the constant current driver and outputs a control signal. Based on the switch state signal and the zero crossing detection signal, the microcontroller adjusts a level of the control signal and controls an electrical connection between the alternating current solid state relay and the alternating current power source.Type: ApplicationFiled: March 16, 2023Publication date: May 30, 2024Inventors: Hui-Chiang Yang, CHIA-CHANG LIN

Patent number: 11996346Abstract: Semiconductor device includes a circuit substrate, a first semiconductor die and a package lid. The first semiconductor die is disposed on and electrically connected to the circuit substrate. The package lid extends over the first semiconductor die and is bonded to the circuit substrate. the package lid comprises a roof extending, a footing and an island. The roof extends along a first direction and a second direction perpendicular to the first direction. The footing is disposed at a peripheral edge of the roof and protrudes from the roof towards the circuit substrate along a third direction perpendicular to the first direction and the second direction. The island protrudes from the roof towards the circuit substrate, wherein the island is disconnected from the footing along the second direction, and the island is physically connected to the footing along the first direction.Type: GrantFiled: May 22, 2023Date of Patent: May 28, 2024Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Shu-Shen Yeh, Po-Yao Lin, Hui-Chang Yu, Shyue-Ter Leu, Shin-Puu Jeng

Patent number: 11979158Abstract: An integrated circuit (IC) device includes a master latch circuit having a first clock input and a data output, a slave latch circuit having a second clock input and a data input electrically coupled to the data output of the master latch circuit, and a clock circuit. The clock circuit is electrically coupled to the first clock input by a first electrical connection configured to have a first time delay between the clock circuit and the first clock input. The clock circuit is electrically coupled to the second clock input by a second electrical connection configured to have a second time delay between the clock circuit and the second clock input. The first time delay is longer than the second time delay.Type: GrantFiled: May 26, 2022Date of Patent: May 7, 2024Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY, LTD.Inventors: Cheng-Yu Lin, Yung-Chen Chien, Jia-Hong Gao, Jerry Chang Jui Kao, Hui-Zhong Zhuang
