    摘要: A semiconductor structure comprises a semiconductor substrate, a first trench capacitor, and a second trench capacitor. The substrate has first trenches arranged in a first arrangement direction with each first trench extending in a first extension direction and second trenches arranged in a second arrangement direction with each second trench extending in a second extension direction. The first trench capacitor includes first capacitor segments disposed inside the first trenches. The second trench capacitor includes second capacitor segments disposed inside the second trenches. One first capacitor segment of the first capacitor segments has an extending length different from that of another first capacitor segment of the first capacitor segments, and one second capacitor segment of the second capacitor segments has an extending length different from that of another second capacitor segment of the second capacitor segments.

    摘要: A package structure and method of manufacturing a package structure are provided. The package structure comprises two semiconductor structures and two bonding layers sandwiched between both semiconductor structures. Each bonding layer has a plurality of bonding pads separated by an isolation layer. Each bonding pad has a bonding surface including a bonding region and at least one buffer region. The bonding regions in both bonding layers bond to each other. The buffer region of one semiconductor structure bonds to the isolation layer of the other semiconductor structure. A ratio of a surface area of the buffer region to that of the bonding region in each metal pad is from about 0.01 to about 10.
