Patent number: 11943077Abstract: A multidrop network system includes N network devices. The N network devices include a master device and multiple slave devices, and each network device has an identification code as its own identification in the multidrop network system. The N network devices have N identification codes and obtain transmission opportunities in turn according to the N identification codes in each round of data transmission. Each network device performs a count operation to generate a current count value, and when the identification code of a network device is the same as the current count value, this network device obtains a transmission opportunity. After a device obtains the transmission opportunity, it determines whether a cut-in signal from another network device is observed in a front duration of a predetermined time slot, and then determines whether to abandon/defer the right to start transmitting in the remaining duration of the predetermined time slot.Type: GrantFiled: May 31, 2022Date of Patent: March 26, 2024Assignee: REALTEK SEMICONDUCTOR CORPORATIONInventors: Yung-Le Chang, Wen-Chih Fang, Deng-Shian Wang, Shieh-Hsing Kuo

Publication number: 20240087950Abstract: Embodiments of improved process flows and methods are provided in the present disclosure to form air gaps between metal interconnects. More specifically, the present disclosure provides improved process flows and methods that utilize a wet etch process to form recesses between metal interconnects formed on a patterned substrate.
