Patent number: 12261086Abstract: A method for fabricating a semiconductor device includes first providing a substrate having a high-voltage (HV) region, a medium-voltage (MV) region, and a low-voltage (LV) region, forming a HV device on the HV region, and forming a LV device on the LV region. Preferably, the HV device includes a first base on the substrate, a first gate dielectric layer on the first base, and a first gate electrode on the first gate dielectric layer. The LV device includes a fin-shaped structure on the substrate, and a second gate electrode on the fin-shaped structure, in which a top surface of the first gate dielectric layer is even with a top surface of the fin-shaped structure.Type: GrantFiled: January 27, 2022Date of Patent: March 25, 2025Assignee: UNITED MICROELECTRONICS CORP.Inventors: Chih-Kai Hsu, Ssu-I Fu, Yu-Hsiang Lin, Chien-Ting Lin, Chun-Ya Chiu, Chia-Jung Hsu, Chin-Hung Chen

Publication number: 20250098187Abstract: A memory cell structure includes a transistor structure and a capacitor structure, where the capacitor structure includes a hydrogen absorption layer. The hydrogen absorption layer absorbs hydrogen, which prevents or reduces the likelihood of the hydrogen diffusing into an underlying metal-oxide channel of the transistor structure. In this way, the hydrogen absorption layer minimizes and/or reduces the likelihood of hydrogen contamination in the metal-oxide channel, which may enable a low current leakage to be achieved for the memory cell structure and reduces the likelihood of data corruption and/or failure of the memory cell structure, among other examples.Type: ApplicationFiled: September 18, 2023Publication date: March 20, 2025Inventors: Yu-Chien CHIU, Chen-Han CHOU, Ya-Yun CHENG, Ya-Chun CHANG, Wen-Ling LU, Yu-Kai CHANG, Pei-Chun LIAO, Chung-Wei WU

Patent number: 12140293Abstract: A light-emitting device includes a base, a shell with a through hole, a circuit board, a first covering body and a second covering body. The shell covers on the base along an installing direction to form an accommodating space. The circuit board is disposed in the accommodating space and includes a light-emitting element configured to emit a light beam to the through hole along a light-emitting direction. A separation distance is formed between the light-emitting element and the through hole. The light-emitting direction is perpendicular to the installing direction. The first covering body and the second covering body are respectively located at a first side and a second side of the circuit board. A covering space is formed by the first covering body and the second covering body and has an opening corresponding to the through hole. The light-emitting element is located in the covering space.Type: GrantFiled: April 26, 2024Date of Patent: November 12, 2024Assignee: WISTRON NEWEB CORPORATIONInventors: Yu-Kai Chiu, Chang-Yu Huang, Wei-Hung Liao

Publication number: 20240191734Abstract: A holed element is plate-shaped and includes a first curved surface, a second curved surface, two interface surfaces, a main hole, two slots, and two elastic sections. A length of the second curved surface is less than a length of the first curved surface. Each of the two interface surfaces is concave relative to the first curved surface and the second curved surface. The main hole is formed and surrounded by the first curved surface, the second curved surface, and the two interface surfaces. The main hole includes a first hole portion and a second hole portion which respectively correspond to the first curved surface and the second curved surface. The two slots are respectively disposed at two opposite sides of the main hole. Each of the elastic sections is formed between a corresponding one of the two slots and the main hole.Type: ApplicationFiled: December 12, 2023Publication date: June 13, 2024Inventor: Yu-Kai CHIU

Publication number: 20240102609Abstract: A suspension bracket and an installing method thereof are provided. The suspension bracket includes a first bracket, a support pole, a positioning member, and a second bracket. The first bracket has an opening and includes a first connecting structure. The support pole is pierced through the opening and configured to be disposed on a preset location, and one end of the support pole abuts against an outer side of the opening. The positioning member is disposed on the support pole and abuts against another outer side of the opening to retain the first bracket. The first bracket is rotatable relative to the positioning member and the support pole. The second bracket includes a second connecting structure, which can be detachably connected to the first connecting structure of the first bracket to form an accommodating space for containing an article.Type: ApplicationFiled: September 21, 2023Publication date: March 28, 2024Inventors: Yu-Kai CHIU, Ming-Hung HUNG

Patent number: 11742573Abstract: An antenna device and an orientation adjustment mechanism are provided. The orientation adjustment mechanism includes a holder, a rotation carrier assembled to the holder, and a torsion spring. The rotation carrier is counterclockwise rotatable from an initial position by a first predetermined angle or is clockwise rotatable from the initial position by a second predetermined angle. The torsion spring has an elastic portion disposed on the holder and two extending arms that extend from the elastic portion. When the rotation carrier is rotated from the initial position by the first predetermined angle or the second predetermined angle, the rotation carrier presses and moves one of the two extending arms, and another one of the two extending arms abuts against the limiting portion, so that the elastic portion is deformed to store an elastic force that tends to move the rotation carrier toward the initial position.Type: GrantFiled: March 22, 2022Date of Patent: August 29, 2023Assignee: WISTRON NEWEB CORPORATIONInventors: Man-Ning Lu, Ming-Hung Hung, Yu-Kai Chiu
