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
