Publication number: 20240113112Abstract: Methods of cutting gate structures and fins, and structures formed thereby, are described. In an embodiment, a substrate includes first and second fins and an isolation region. The first and second fins extend longitudinally parallel, with the isolation region disposed therebetween. A gate structure includes a conformal gate dielectric over the first fin and a gate electrode over the conformal gate dielectric. A first insulating fill structure abuts the gate structure and extends vertically from a level of an upper surface of the gate structure to at least a surface of the isolation region. No portion of the conformal gate dielectric extends vertically between the first insulating fill structure and the gate electrode. A second insulating fill structure abuts the first insulating fill structure and an end sidewall of the second fin. The first insulating fill structure is disposed laterally between the gate structure and the second insulating fill structure.Type: ApplicationFiled: December 1, 2023Publication date: April 4, 2024Inventors: Ryan Chia-Jen Chen, Cheng-Chung Chang, Shao-Hua Hsu, Yu-Hsien Lin, Ming-Ching Chang, Li-Wei Yin, Tzu-Wen Pan, Yi-Chun Chen

Patent number: 11286969Abstract: A fastening structure includes an operating engaging element and a body portion. The operating engaging element has an engaging portion and an operating portion. The operating portion has a moving surface abutting against a corresponding moving surface of the operating engaging element to cause movement of the operating engaging element. The body portion has a mounting portion which the operating engaging element is mounted on; or the operating engaging element has a mounting portion which the body portion is mounted. With the engaging portion, the operating engaging element is fastened to an object, and the body portion is fastened to another object, thereby fastening the two objects together. Unfastening the two objects entails pressing the operating portion such that the moving surface of the operating portion abuts against the corresponding moving surface of the operating engaging element to cause movement of the operating engaging element, thereby separating the objects.Type: GrantFiled: December 27, 2018Date of Patent: March 29, 2022Assignee: FIVETECH TECHNOLOGY INC.Inventors: Ting-Jui Wang, Hsien-Chang Chen

Publication number: 20210364019Abstract: A fastener structure includes a casing, an engaging element and a controlling element. The engaging element is movably disposed at the casing. The controlling element is movably disposed at the casing. The controlling element controls the engaging element to enter a locked state or unlocked state. Therefore, the casing is fitted to the first object, such that engaging element is fastened to or unfastened from the second object, so as to couple together quickly and separate easily at least two objects.Type: ApplicationFiled: March 30, 2021Publication date: November 25, 2021Inventors: TING-JUI WANG, HSIEN-CHANG CHEN

Publication number: 20200200216Abstract: A sliding positioning structure includes a seat, a first fastening body and a second fastening body. The first fastening body is movably assembled at the seat. The second fastening body is provided at the seat, and is for longitudinally fastening, latitudinally fastening or rotationally fastening to a first object. Accordingly, the seat can be quickly assembled with the first object by using the second fastening body, and be coupled with or removed from a second object by using the first fastening body, thereby accomplishing coupling or disengagement of two objects and achieving effects of repeated and quickly coupling and disengagement.Type: ApplicationFiled: December 20, 2019Publication date: June 25, 2020Inventors: TING-JUI WANG, HSIEN-CHANG CHEN

Publication number: 20090207410Abstract: A position adjustment mechanism for laser optics includes a fixed mount, a fastening member, and a position regulation device. The fixed mount is connected to a heat-dissipating mount and positioned near the optics mount. The fastening member penetrates the fixed mount and the optics mount to connect the fixed mount with the optics mount and maintains a gap between the fixed mount and the optics mount. The position regulation device is positioned in the vicinity of the fastening member and in the gap between the fixed mount and the optics mount. The position regulation device presses against the optics mount to adjust the position of the reflective element relative to the light-emitting device.Type: ApplicationFiled: January 21, 2009Publication date: August 20, 2009Inventors: Yung-Kuang Liu, Chih-Shun Huang, Hsien-Chang Chen, Tung-Chun Chiang

Patent number: 6604830Abstract: A color wheel comprises a motor, a plurality of filter segments and an obstructing plate. The motor has a rotating casing. Protruding from the center of an upper side of the rotating casing, there is a rotating shaft. One end of each fan-shaped filter segment is in contact with the rotating shaft, and one side of its lower surface has a formation of a glue area to be glued onto an upper side of the motor, forming a rear clearance from the upper side. The filter segments are joined to each other to become a ring shape surrounding the rotating shaft. A center hole of the ring-shaped obstructing plate is mounted on the rotating shaft, keeping a clearance from the filter segment. On the outside of the obstructing plate is a ring recess. The invention provides ways of heat insulation and radiation for the filter segments, to enhance product quality.Type: GrantFiled: July 23, 2002Date of Patent: August 12, 2003Assignee: Young Optics Inc.Inventors: Hsien-Chi Chiu, Lang-Fu Tsai, Hsien-Chang Chen
