Publication number: 20240120282Abstract: The present application discloses a semiconductor structure and methods for manufacturing semiconductor structures. The semiconductor structure includes a plurality of bottom dies and a top die stacked on the bottom dies. The bottom dies receive power supplies through tiny through silicon vias (TSVs) formed in backside substrates of the bottom dies, while the top die receives power supplies through dielectric vias (TDVs) formed in a dielectric layer that covers the bottom dies. By enabling backside power delivery to the bottom die, more space can be provided for trace routing between stacked dies. Therefore, greater computation capability can be achieved within a smaller chip area with less power loss.Type: ApplicationFiled: February 20, 2023Publication date: April 11, 2024Inventors: TZU-WEI CHIU, CHUN-WEI CHANG, SHANG-PIN CHEN, WEI-CHIH CHEN, CHE-YEN HUANG

Patent number: 10361047Abstract: The present application discloses a pressure switch which includes a tube structure, a pressure transmitting assembly, a microswitch, and corrugated sheets. The pressure transmitting assembly disposed inside the tube structure includes a guide rod with a piston, and a fluid chamber providing working pressure is defined between the piston and a fluid inlet. The microswitch is disposed at another end of the tube structure away from the fluid inlet and can be actuated by the guide rod. The corrugated sheets are fixed inside the tube structure and stacked on the piston structure so as to form a sealing and pressure transmitting interface for the pressure switch. Therefore, the pressure switch has good sealing property, good buffering capacity, and enhanced mechanical response rate with the corrugated sheets and is suitable for precision pressure measurement and control in an environment with high pressure and high frequency vibration.Type: GrantFiled: July 9, 2018Date of Patent: July 23, 2019Assignee: National Chung-Shan Institute of Science and TechnologyInventors: Kwei-Chi Tsay, Che-Pin Chen, Zong-Ham Wu
