    摘要: A structure includes a substrate, and an interconnect structure over the substrate. The structure further includes a through-substrate-via (TSV) extending through the interconnect structure and into the substrate, the TSV comprising a conductive material layer. The structure further includes a dielectric layer having a first portion over the interconnect structure and a second portion within the TSV, wherein the first portion and the second portion comprise a same material. The conductive material layer includes a first section separated from substrate by the second portion of the dielectric layer. The conductive material layer further includes a second section over a top surface of the second portion of the dielectric layer. The conductive material layer further includes a third section over the second section, wherein the third section has a width greater than a width of the second section.

    摘要: A semiconductor device and a semiconductor manufacturing method thereof are provided. The semiconductor manufacturing method includes the following streps. A first semiconductor element with a first bonding film is formed. The first bonding film is formed on a first side of the first semiconductor element. The first semiconductor element and the first bonding film form a taper structure. The first bonding film forms a wide portion of the taper structure. The first semiconductor element forms a narrow portion of the taper structure. A second semiconductor element with a second bonding film is formed. The second bonding film is formed on the second semiconductor element. The first semiconductor element and the second semiconductor element are bonded by bonding the first bonding film and the second bonding film. An oxide layer is filled to surround the first semiconductor element and the first bonding film.
