Publication number: 20240088224Abstract: A semiconductor structure includes a first gate structure, a second gate structure coupled to the first gate structure, a source region, a first drain region, and a second drain region. The source region is surrounded by the first gate structure and the second gate structure. The first drain region is separated from the source region by the first gate structure. The second drain region is separated from the source region by the second gat structure. A shape of the first drain region and a shape of the second drain region are different from each other from a plan view.Type: ApplicationFiled: November 14, 2023Publication date: March 14, 2024Inventors: HSING-I TSAI, FU-HUAN TSAI, CHIA-CHUNG CHEN, HSIAO-CHUN LEE, CHI-FENG HUANG, CHO-YING LU, VICTOR CHIANG LIANG

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

Publication number: 20200340599Abstract: The present invention is a pressure reducing valve comprising a valve body and a piston. The interior of the valve body has a water inlet channel, a water outlet channel, a chamber between the water inlet channel and the water outlet channel, a wall separating the chamber and the water inlet channel, and a tube disposed at the wall and connecting the chamber to the water inlet channel. The piston is positioned inside the chamber and movable between an original position and a closed position. The piston only closes off the rear opening of the tube at the closed position, wherein the valve body is an integral structure and entirely made of the hard-plastic material. The piston has an integral structure made of TPE material. The rear opening of the tube is blocked when the piston is at the closed position.Type: ApplicationFiled: April 23, 2019Publication date: October 29, 2020Inventor: Fu-Chung Tsai

Patent number: 9638346Abstract: This invention discloses a valve including a body, an upper membrane, a lower membrane and a positioning block. The body has an upper channel, a lower channel, an accommodation space and a valve groove. The accommodation space defines an upper opening and a lower opening for respectively communicating with the upper channel and the lower channel. The valve groove is near the intersection of the lower channel and the accommodation space respectively communicating therewith. The upper and the lower membrane block the upper opening of the accommodation space and the lower opening. The positioning block is disposed between the upper membrane and the lower membrane and is able to push the lower membrane into the valve groove and abut against a sidewall of the valve groove. The valve is able to block the flow of water in the valve when the water flow is needed to be cut off.Type: GrantFiled: December 4, 2014Date of Patent: May 2, 2017Inventor: Fu-Chung Tsai

Publication number: 20120285570Abstract: A pipe joint, capable of absorbing water hammer shock, includes a tubular body, an elastic gasket, an inlet conduit and an outlet conduit. The tubular body has a passageway therethrough in which the elastic gasket is disposed. The elastic gasket divides the passageway of the tubular body into a first room and a second room and defines therein a plurality of holes each communicating with the first and second rooms. The inlet conduit is joined to one end of the tubular body and has a port in fluid communication with the first room of the tubular body. And, the outlet conduit is joined to the other end of the tubular body and has a port in fluid communication with the second room of the tubular body.Type: ApplicationFiled: May 9, 2011Publication date: November 15, 2012Inventor: Fu-Chung TSAI

Patent number: 6401966Abstract: A plastic pressure vessel structure includes a diaphragm mounted in a plastic outer barrel for dividing the plastic outer barrel into an upper chamber containing a liquid, and a lower chamber containing a pressurized gas, and a plastic inner barrel fully mounted in the lower chamber. In such a manner, the wall of the inner barrel and the wall of the lower chamber are overlapped with each other, such that capillary pores of the wall of the inner barrel and capillary pores of the wall of the lower chamber are arranged in a staggered manner, thereby reducing the capillary action, so as to provide a tight sealing effect in the lower chamber, thereby preventing the pressurized gas contained in the lower chamber from leaking outward, and thereby preventing the pressure contained in the lower chamber from being reduced.Type: GrantFiled: April 11, 2001Date of Patent: June 11, 2002Inventor: Fu Chung Tsai
