Patent number: 11965522Abstract: An impeller includes a hub and a plurality of blades. The blades are arranged around the hub, and each blade includes a leading edge, a blade tip, a root portion, a trailing edge, a windward side and a leeward side. The windward side including a first turning point and a second turning point, a first vertical height difference is formed from the blade tip to the first turning point, and a second vertical height difference is formed from the first turning point to the second turning point, and the first vertical height difference is greater than the second vertical height difference. The impeller apparently reduces the noise.Type: GrantFiled: January 28, 2022Date of Patent: April 23, 2024Assignee: DELTA ELECTRONICS, INC.Inventors: Pei-Han Chiu, Chien-Ming Lee, Chung-Yuan Tsang, Chao-Fu Yang

Publication number: 20240090336Abstract: A method for fabricating magnetoresistive random-access memory cells (MRAM) on a substrate is provided. The substrate is formed with a magnetic tunneling junction (MTJ) layer thereon. When the MTJ layer is etched to form the MRAM cells, there may be metal components deposited on a surface of the MRAM cells and between the MRAM cells. The metal components are then removed by chemical reaction. However, the removal of the metal components may form extra substances on the substrate. A further etching process is then performed to remove the extra substances by physical etching.Type: ApplicationFiled: November 17, 2023Publication date: March 14, 2024Applicant: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY, LTD.Inventors: Chang-Lin YANG, Chung-Te LIN, Sheng-Yuan CHANG, Han-Ting LIN, Chien-Hua HUANG

Publication number: 20240084455Abstract: Some implementations described herein include systems and techniques for fabricating a wafer-on-wafer product using a filled lateral gap between beveled regions of wafers included in a stacked-wafer assembly and along a perimeter region of the stacked-wafer assembly. The systems and techniques include a deposition tool having an electrode with a protrusion that enhances an electromagnetic field along the perimeter region of the stacked-wafer assembly during a deposition operation performed by the deposition tool. Relative to an electromagnetic field generated by a deposition tool not including the electrode with the protrusion, the enhanced electromagnetic field improves the deposition operation so that a supporting fill material may be sufficiently deposited.Type: ApplicationFiled: February 8, 2023Publication date: March 14, 2024Inventors: Che Wei YANG, Chih Cheng SHIH, Kuo Liang LU, Yu JIANG, Sheng-Chan LI, Kuo-Ming WU, Sheng-Chau CHEN, Chung-Yi YU, Cheng-Yuan TSAI

Patent number: 10644130Abstract: A metal-oxide-semiconductor field-effect transistor (MOSFET) includes a substrate, a source and a drain in the substrate, a gate electrode disposed over the substrate between the source and drain. An inner spacer is disposed at least partially over the gate electrode. An outer spacer is disposed adjacent to a sidewall of the gate electrode.Type: GrantFiled: October 25, 2012Date of Patent: May 5, 2020Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Chung-Yuan Yang, Jen-Pan Wang

Patent number: 9596907Abstract: A fastening unit includes a base, a fixing seat, two shaft seats, a main body, an engaging member, and an abutting member. The fixing seat and the two shaft seats are disposed on the base. The main body is detachably disposed on the two shaft seats. The engaging member is connected to the side of the main body that is away from the two shaft seats. The abutting member protrudes from the bottom surface of the main body. When the fastening unit is in a closed state, the engaging member engages with the fixing seat. As a result, the bottom surface faces the base, and the abutting member is adjacent to the base. When the fastening unit is transferred from the closed state to an opened state, the engaging member disengages from the fixing seat, and the main body pivots relative to the two shaft seats.Type: GrantFiled: August 24, 2015Date of Patent: March 21, 2017Assignee: Wistron NeWeb Corp.Inventors: Chung-Yuan Yang, Jen-Yung Chang

Patent number: 8648341Abstract: Methods and apparatuses for sharing test pads among function blocks under test within multiple layers of a die are disclosed. A semiconductor wafer comprises a first die and a second die separated by a scribe line. A first pad, a second pad, and a third pad are located in the scribe line. The test pads may be located within a die as well. The first pad and the second pad are used to test a first function block within a first layer, and the first pad and the third pad are used to test a second function block within a second layer of the first die. The shared first test pad are used to test multiple function blocks contained in different layers of the die. Therefore fewer test pads are needed which leads to reduced area for scribe lines in a wafer.Type: GrantFiled: February 23, 2012Date of Patent: February 11, 2014Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Chung-Yuan Yang, Jen-Pan Wang, Jiun-Jie Huang

Patent number: 5454228Abstract: A liquid refrigeration system for providing cooling operations, including an evaporator with its refrigerant outlet connected to a vapor/liquid separator so that refrigerant in the refrigerant conduits in the evaporator may undergo heat exchange in the form of a mixture of vapor and liquid. The compressor of the system outputs high pressure refrigerant vapor which passes through a specially designed condenser before being conveyed to a thermostatic expansion valve at the front end of the inlet of the evaporator. Low-pressure oil-rich liquid refrigerant separated by the vapor/liquid separator first passes through the condenser to become superheated vapor and it is then sent to the suction line of the compressor together with the saturated refrigerant vapor from the vapor/liquid separator. The expansion valve meters the flow rate of system refrigerant and has a temperature sensor which detects the superheat of the low pressure refrigerant vapor leaving the condenser.Type: GrantFiled: June 7, 1994Date of Patent: October 3, 1995Assignee: Industrial Technology Research InstituteInventors: Chung-Yuan Yang, Chin-Hung Lo, Yu-Kun Hung, Mao-Yung Weng, Yie-Zu Hu
