Publication number: 20240136291Abstract: Semiconductor devices and methods of forming the same are provided. In some embodiments, a method includes receiving a workpiece having a redistribution layer disposed over and electrically coupled to an interconnect structure. In some embodiments, the method further includes patterning the redistribution layer to form a recess between and separating a first conductive feature and a second conductive feature of the redistribution layer, where corners of the first conductive feature and the second conductive feature are defined adjacent to and on either side of the recess. The method further includes depositing a first dielectric layer over the first conductive feature, the second conductive feature, and within the recess. The method further includes depositing a nitride layer over the first dielectric layer. In some examples, the method further includes removing portions of the nitride layer disposed over the corners of the first conductive feature and the second conductive feature.Type: ApplicationFiled: January 12, 2023Publication date: April 25, 2024Inventors: Hsiang-Ku SHEN, Chen-Chiu HUANG, Chia-Nan LIN, Man-Yun WU, Wen-Tzu CHEN, Sean YANG, Dian-Hao CHEN, Chi-Hao CHANG, Ching-Wei LIN, Wen-Ling CHANG

Publication number: 20240088208Abstract: A method for forming a semiconductor device structure is provided. The method includes forming an interconnect structure over a substrate. The method includes forming a first conductive pad and a mask layer over the interconnect structure. The mask layer covers a top surface of the first conductive pad. The method includes forming a metal oxide layer over a sidewall of the first conductive pad. The method includes forming a second conductive pad over the first conductive pad and passing through the mask layer. The first conductive pad and the second conductive pad are made of different materials.Type: ApplicationFiled: January 11, 2023Publication date: March 14, 2024Inventors: Tzu-Ting LIU, Hsiang-Ku SHEN, Wen-Tzu CHEN, Man-Yun WU, Wen-Ling CHANG, Dian-Hau CHEN

Patent number: 8503433Abstract: A method of processing a Voice over Internet Protocol (VoIP) call is disclosed. The method includes receiving a Uniform Resource Identifier (URI) associated with a destination telephone number from a telephone number mapping (ENUM) server associated with a third service provider. The method also includes receiving an Internet Protocol (IP) address of a Session Initiation Protocol (SIP) server associated with a second service provider in response to a query by a first service provider to a Domain Name Service (DNS) server. The query is based on the URI. Additionally, the method includes contacting the SIP server using the IP address of the SIP server to set up a bearer path of the VoIP call.Type: GrantFiled: April 6, 2009Date of Patent: August 6, 2013Assignee: AT&T Intellectual Property I, L.P.Inventors: Armstrong Soo, Blair Lane Porter, Bernard Siu-Man Ku, Phyllis G.

Patent number: 8175251Abstract: At least one telephone network element receives an attempt of a caller to place a telephone call to a callee. A telephone number for the call is registered in a telephone number mapping (ENUM) database to receive incoming telephone calls via a Voice over Internet Protocol (VoIP) network. The at least one telephone network element receives an indication of a preference of the caller to carry the telephone call via one of a public switched telephone network (PSTN) and a public land mobile network (PLMN), instead of via the VoIP network. Based on the preference, the method inhibits an ENUM query of the ENUM database for the telephone call and forwards the telephone call to a gateway to carry the telephone call to the callee via one of the PSTN and the PLMN instead of via the VoIP network.Type: GrantFiled: October 23, 2009Date of Patent: May 8, 2012Assignee: AT&T Intellectual Property I, L.P.Inventors: Bernard Siu-Man Ku, Alex Huang, Armstrong Soo

Patent number: 8085757Abstract: A telephone number of the callee is received from a caller device. An Internet protocol Multimedia Subsystem (IMS)-based telephone number mapping (ENUM) query is constructed based on the telephone number of the callee. An ENUM database is queried based on the ENUM query. If a response to the ENUM query is absent a Session Initiation Protocol (SIP) Uniform Resource Indicator (URI) or a telephone (TEL) URI, the telephone number is resolved into one or more non-SIP/non-TEL URIs usable to communicate with the callee. The caller is enabled to use the caller device or other devices to select which of the one or more non-SIP/non-TEL URIs to use to communicate with the callee. For each caller-selected non-SIP/non-TEL URI, communication in a protocol associated with the URI is initiated between the caller and the callee using the caller device or other devices.Type: GrantFiled: November 7, 2005Date of Patent: December 27, 2011Assignee: AT&T Intellectual Property I, L.P.Inventors: Bernard Siu-Man Ku, Mehrad Yasrebi

Patent number: 7702092Abstract: A method of determining a telephony network node for routing a call is disclosed. The method includes receiving a call request at a service provider node, the call request including a called number to reach a called party. The method further includes sending a combined telephone number mapping (ENUM) and local number portability (LNP) query from the service provider node to a remote ENUM database, the combined ENUM/LNP query including the called number. The method further includes receiving a response to the combined ENUM/LNP query at the service provider node. The response includes one of an internet protocol address that identifies a node of an internet protocol network, a local routing number (LRN) to be used to route the call to a uniquely identified switching node of a circuit-switched network, or a return of the called number to indicate that the called number can be used to route the call to the called party.Type: GrantFiled: May 2, 2005Date of Patent: April 20, 2010Assignee: AT&T Intellectual Property I, L.P.Inventors: Niral Sheth, Bernard Siu-Man Ku, Jeffrey Paul Johnson

Publication number: 20100091975Abstract: A method of routing a call includes sending a second query when a telephone number mapping (ENUM) database does not identify an internet protocol (IP) address associated with a called number in response to a first query. The second query is directed to a local number portability (LNP) database to determine whether the called number includes a ported number having an associated local routing number (LRN).Type: ApplicationFiled: December 15, 2009Publication date: April 15, 2010Applicant: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Niral Sheth, Bernard Siu-Man Ku, Jeffrey Paul Johnson

Patent number: 7529231Abstract: A Voice over Internet Protocol (VoIP) call from a first provider to a destination telephone number served by a second provider comprises sending a Session Initiation Protocol (SIP) INVITE message from an originating switch to a first SIP server of the first provider. The first SIP server queries a telephone number mapping (ENUM) server of either the first, second or a third provider, and receives a Uniform Resource Identifier (URI) associated with the destination telephone number. The ENUM server may be internal or external to the first provider. The first provider queries a Domain Name Service (DNS) server based on the URI, and receives an Internet Protocol (IP) address of a second SIP server of the second provider. The first SIP server and the second SIP server are used to set up a bearer path for the VoIP call between the originating switch and a destination switch.Type: GrantFiled: January 13, 2006Date of Patent: May 5, 2009Assignee: AT&T Intellectual Property L.L.P.Inventors: Armstrong Soo, Blair Lane Porter, Bernard Siu-Man Ku, Phyllis G.
