Patent number: 11942467Abstract: A semiconductor structure includes a first metal-dielectric-metal layer, a first dielectric layer, a first conductive layer, a second conductive layer, and a second dielectric layer. The first metal-dielectric-metal layer includes a plurality of first fingers, a plurality of second fingers, and a first dielectric material. The first fingers are electrically connected to a first voltage. The second fingers are electrically connected to a second voltage different from the first voltage, and the first fingers and the second fingers are arranged in parallel and staggeredly. The first dielectric material is between the first fingers and the second fingers. The first dielectric layer is over the first metal-dielectric-metal layer. The first conductive layer is over the first dielectric layer. The second conductive layer is over the first conductive layer. The second dielectric layer is between the first conductive layer and the second conductive layer.Type: GrantFiled: June 18, 2021Date of Patent: March 26, 2024Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.Inventors: I-Sheng Chen, Yi-Jing Li, Chia-Ming Hsu, Wan-Lin Tsai, Clement Hsingjen Wann

Patent number: 11923205Abstract: A method for manufacturing a semiconductor device includes: providing a wafer-bonding stack structure having a sidewall layer and an exposed first component layer; forming a photoresist layer on the first component layer; performing an edge trimming process to at least remove the sidewall layer; and removing the photoresist layer. In this way, contaminant particles generated from the blade during the edge trimming process may fall on the photoresist layer but not fall on the first component layer, so as to protect the first component layer from being contaminated.Type: GrantFiled: December 17, 2021Date of Patent: March 5, 2024Assignee: UNITED MICROELECTRONICS CORPORATIONInventors: Kun-Ju Li, Ang Chan, Hsin-Jung Liu, Wei-Xin Gao, Jhih-Yuan Chen, Chun-Han Chen, Zong-Sian Wu, Chau-Chung Hou, I-Ming Lai, Fu-Shou Tsai

Patent number: 10419874Abstract: An indoor positioning system and method that correlates map locations to respective wireless access point (AP) fingerprints, and wherein each wireless AP fingerprint is a plurality of wireless AP signal measurements associated with the correlated map location. The method includes receiving position-inference data associated with a user; determining a probable location inside the building based on the position-inference data; receiving wireless AP signal measurements detected by a wireless device associated with the user; associating the probable location with the wireless device based on the association between the position-inference data and the user of the wireless device; and updating the wireless AP fingerprint correlated to the probable location using the received wireless AP signal measurements. The method and system use crowd-sourcing to build and refine the wireless AP fingerprints.Type: GrantFiled: March 4, 2016Date of Patent: September 17, 2019Assignee: BlackBerry LimitedInventors: I-Ming Tsai, Krishnam Raju Jampani, Jason Christopher Beckett, Daryl Joseph Martin, Jerry Mailloux

Patent number: 9955316Abstract: A method of determining room occupancy of a room in a facility having an indoor positioning system with wireless access point fingerprints each correlated to a location in the facility. The method may include receiving a request from a computing device for a room occupancy assessment associated with the room. It may further include obtaining location data that correlates to the location of one or more people from the indoor positioning system and determining from the location data associated with the room whether the room is occupied. The determination of whether the room is occupied is then sent to the computing device.Type: GrantFiled: July 20, 2015Date of Patent: April 24, 2018Assignee: BlackBerry LimitedInventors: Krishnam Raju Jampani, Daryl Joseph Martin, I-Ming Tsai, Jason Christopher Beckett

Patent number: 9680642Abstract: In order to overcome the limitation of the prior art quantum key terminal equipment not being able to operate across different segments, the present invention discloses a quantum cryptography service network implementation technique to let a point-to-point quantum key equipment in one segment be redesigned to cooperate with other quantum key equipment in other segments to form a quantum key service network. As opposed to the prior art technique of having each segment generates its own quantum key, the present invention can map one pair of quantum key equipment with another pair of quantum key equipment, or map multiple pairs of quantum key equipment connected in series to have quantum keys entirely or partly shared by the quantum key equipment. Therefore, the generated quantum keys can be used across different segments. Each node in the quantum key service network can provide the quantum key to nearby telecommunication equipment in the telecommunication network of the same premises.Type: GrantFiled: February 17, 2011Date of Patent: June 13, 2017Assignee: CHUNGHWA TELECOM CO., LTD.Inventors: Tzuoh-Chyau Yeh, I-Ming Tsai

Patent number: 9164161Abstract: Mobile devices are able to determine their location based radio transmitters that are visible at the device to provide geographic location services. A knowledge of the location of the transmitters is required for the mobile device to determine a location estimate, however this can be difficult in network environments where the transmitters are temporary and their locations are not identified in location databases. Locations of temporary transmitters can be provided to mobile devices in order to augment the available location data used in determining the mobile device location. 3rd parties can provide temporal location data on transmitters that are set up for short period of time, as well as better control the distribution of the location data.Type: GrantFiled: February 4, 2013Date of Patent: October 20, 2015Assignee: BlackBerry LimitedInventors: Bruce Allen Bernhardt, Jingwei Xu, I-Ming Tsai
