Publication number: 20240040800Abstract: Various embodiments of the present disclosure are directed towards a memory cell comprising a blocking layer configured to block diffusion of metal from an electrode of the memory cell to a ferroelectric layer of the memory cell. More particularly, the blocking layer and the ferroelectric layer are between a top electrode of the memory cell and a bottom electrode of the memory cell, which both comprise metal. Further, the blocking layer is between the ferroelectric layer and the electrode, which corresponds to one of the top and bottom electrodes. In some embodiments, the metal of the one of the top and bottom electrodes has a lowest electronegativity amongst the metals of top and bottom electrodes and is hence the most reactive and likely to diffuse amongst the metals of top and bottom electrodes.Type: ApplicationFiled: January 5, 2023Publication date: February 1, 2024Inventors: Tzu-Yu Chen, Chu-Jie Huang, Wan-Chen Chen, Fu-Chen Chang, Sheng-Hung Shih, Kuo-Chi Tu

Publication number: 20230043884Abstract: Various embodiments of the present disclosure are directed towards methods for forming conductive lines and conductive sockets using mandrels with turns, as well as the resulting conductive lines and sockets. A conductive socket of the present disclosure may have a top layout with at least one turn and with a width that is substantially the same as that of conductive lines along the at least one turn. Such a top layout may reduce loading during formation of the conductive socket. Conductive lines of the present disclosure may comprise outer conductive lines and inner conductive lines having ends laterally offset from ends of the outer conductive lines along lengths of the conductive lines. Formation of the inner and outer conductive lines using a mandrel with a turn may enlarge a process window while cutting ends of a sidewall spacer structure from which the inner and outer conductive lines are formed.Type: ApplicationFiled: February 2, 2022Publication date: February 9, 2023Inventors: Harry-Hak-Lay Chuang, Kuo-Chyuan Tzeng, Wan-Chen Chen, Chang-Chih Huang

Publication number: 20200112633Abstract: A method for using an intercom to implement an intelligent calling process, an intelligent calling apparatus and a system is presented. The method is adapted to a site that adopts intercoms to perform a calling process. The system utilizes a server for receiving a calling signal generated by an intelligent calling apparatus. The calling signal records ID information used to represent a calling location. The server obtains the calling location by querying a database. The software process running in the server combines voice signals according to the calling location. A calling voice is generated and sent to the intercoms carried by the personnel member. When any personnel members receive the calling voice by the intercom, this calling process can be completed as the personnel member arrives at the calling location.Type: ApplicationFiled: October 4, 2018Publication date: April 9, 2020Inventors: LI-WEN LIAO, WAN-CHEN CHEN, YEN-TING HO

Publication number: 20200068369Abstract: The disclosure is related to an IoT service system with a Bluetooth Low Energy mesh network, and a communication method thereof. The IoT service system includes multiple intelligent service calling devices, multiple service communication devices and an agent node forming a BLE mesh network. One service calling device generates a service request signal that is broadcasted over a BLE mesh network. When a server receives the service request signal through the agent node, a service personnel and his portable service communication device are obtained by querying a database according to identification information relating to the service calling device that generates the service request signal. A service calling signal is therefore formed and broadcasted over the BLE mesh network. If a distance between the service communication device and the service calling device reaches a threshold while the service personnel is in service, a service dismissing signal is generated.Type: ApplicationFiled: August 27, 2018Publication date: February 27, 2020Inventors: LI-WEN LIAO, JINN-YUAN LAY, YEN-TING HO, WAN-CHEN CHEN

Publication number: 20200068370Abstract: The disclosure is related to a method for intelligent calling service, an apparatus and a system thereof. The method is performed in a server. When the server receives a service request signal recording a device ID generated by an apparatus for intelligent calling service, call information of service personnel can be obtained based on a service location corresponding to the device ID by querying a database of the server. After that, the server issues a service call signal to service communication devices carried by the service personnel. When a distance between the service communication device and the apparatus for intelligent calling service reaches a threshold, it shows that one of the service personnel is in service. This calling service procedure is done when the server receives a dismissing signal generated by the apparatus or the service communication device near the apparatus.Type: ApplicationFiled: August 27, 2018Publication date: February 27, 2020Inventors: LI-WEN LIAO, YEN-TING HO, WAN-CHEN CHEN
