    Abstract: 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.

  • Publication number: 20230402243
    Abstract: The present invention relates to a protection element having a cover. The protection element has a base and a cover. The base has a low melting point alloy layer. The cover has a receiving recess and a guiding passage. The guiding passage corresponds to a melting area of the low melting point alloy layer. The flux is arranged on the accommodating groove of the cover body. When the flux is melted, the flux flows to the guiding passage so that the flux is kept on the melting area of the low melting point alloy layer. Therefore, it is only necessary to place the flux in the receiving recess during manufacture, which can effectively reduce the manufacturing steps and thus reduce the production cost.
