Patent number: 11978740Abstract: A layer stack including a first bonding dielectric material layer, a dielectric metal oxide layer, and a second bonding dielectric material layer is formed over a top surface of a substrate including a substrate semiconductor layer. A conductive material layer is formed by depositing a conductive material over the second bonding dielectric material layer. The substrate semiconductor layer is thinned by removing portions of the substrate semiconductor layer that are distal from the layer stack, whereby a remaining portion of the substrate semiconductor layer includes a top semiconductor layer. A semiconductor device may be formed on the top semiconductor layer.Type: GrantFiled: February 17, 2022Date of Patent: May 7, 2024Assignee: Taiwan Semiconductor Manufacturing Company LimitedInventors: Harry-Hak-Lay Chuang, Kuo-Ching Huang, Wei-Cheng Wu, Hsin Fu Lin, Henry Wang, Chien Hung Liu, Tsung-Hao Yeh, Hsien Jung Chen

Publication number: 20200007431Abstract: A reliability evaluating method for a multi-state flow network and a system thereof are presented. The method includes following steps: finding candidate path sets included in the multi-state flow network; converting the candidate path sets into candidate path values according to a prime number function; removing the repeated candidate path values to keep the corresponded candidate path sets as the non-repeated minimal path; calculating the reliability of the multi-state flow network based on the data flow and data load of the minimal path sets.Type: ApplicationFiled: September 24, 2018Publication date: January 2, 2020Inventors: WEI-CHANG YEH, WEI-HUNG YEH

Publication number: 20050093818Abstract: A laser projection display apparatus includes a laser that emits a light beam. Actuators steer the light beam in horizontal and vertical directions to generate the display images. Each of the actuators includes first and second mirrors, each of which is suspended by a gimbal. Each of the mirrors rotates responsive to current flow through a coil attached to a backside of the mirror in the presence of a magnetic field. A digital signal process provides integrated control of the actuators and laser power based on the content of a display program. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.Type: ApplicationFiled: November 5, 2003Publication date: May 5, 2005Applicant: Lightbay Networks CorporationInventors: Shahab Hatam-Tabrizi, Wei-Hung Yeh, Mansur Bashardoust

Publication number: 20050002602Abstract: A photonic switch for an optical communication network includes a matrix of actuator-mirror assemblies and a corresponding matrix of optical ports. A first one of the actuator-mirror assemblies directs a beam of light received from an input optical port to a reference mirror, where it is reflected to a second actuator-mirror assembly that redirects the beam to an output optical port. Each of the actuator-mirror assemblies includes a mirror-coil assembly mounted to a gimbal, with stationary magnets being positioned adjacent a corresponding one of the coils such that when current flows through the coils a force is generated that causes the mirror-coil assembly to tilt. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).Type: ApplicationFiled: July 29, 2004Publication date: January 6, 2005Applicant: Lightbay Networks CorporationInventors: Shahab Hatam-Tabrizi, Mansur Kiadeh, Wei-Hung Yeh

Patent number: 6828698Abstract: A gimbal for supporting a moveable mirror includes an attachment section, first and second pairs of beams extending along the x-axis and connected to the attachment section, and third and fourth pairs of beams extending along the y-axis connected with the first and second pair of beams. The connections are such that the mirror can tilt or rotate about both the x-axis and y-axis. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.Type: GrantFiled: June 13, 2002Date of Patent: December 7, 2004Assignee: Lightbay Networks CorporationInventors: Shahab Hatam-Tabrizi, Wei-Hung Yeh

Patent number: 6720682Abstract: An actuator for tilting a moveable object such as a mirror includes a base and a coil-object assembly that includes first and second pairs of coils each of which is attached to the object, the first pair of coils being arranged along a longitudinal axis, and the second pair of coils being arranged along a transverse axis substantially orthogonal to the longitudinal axis. A gimbal has an attachment section attached to the object, and mounting sections connected via a plurality of beams to the attachment section, the mounting sections being attached to the base. A permanent magnet is positioned adjacent a corresponding one of each of the coils such that when current flows through the coils a rotational force is generated that causes the coil-object assembly to rotate about an axis.
