    摘要: A method for fabricating semiconductor device includes: forming a fin-shaped structure on a substrate, wherein the fin-shaped structure is extending along a first direction; forming a gate layer on the fin-shaped structure; removing part of the gate layer and part of the fin-shaped structure to form a first trench for dividing the fin-shaped structure into a first portion and a second portion, wherein the first trench is extending along a second direction; forming a patterned mask on the gate layer and into the first trench; removing part of the gate layer to form a second trench, wherein the second trench is extending along the first direction; and filling a dielectric layer in the first trench and the second trench.

    摘要: A method for fabricating semiconductor device includes the steps of: forming a fin-shaped structure on a substrate; forming a first gate structure and a second gate structure on the fin-shaped structure; forming an interlayer dielectric (ILD) layer around the first gate structure and the second gate structure; removing the second gate structure and part of the fin-shaped structure to forma first trench; forming a dielectric layer into the first trench; and planarizing part of the dielectric layer to form a single diffusion break (SDB) structure. Preferably, the top surfaces of the SDB structure and the first gate structure are coplanar.

    摘要: A through silicon via structure is located in a recess of a substrate. The through silicon via structure includes a barrier layer, a buffer layer and a conductive layer. The barrier layer covers a surface of the recess. The buffer layer covers the barrier layer. The conductive layer is located on the buffer layer and fills the recess, wherein the contact surface between the conductive layer and the buffer layer is smoother than the contact surface between the buffer layer and the barrier layer. Moreover, a through silicon via process forming said through silicon via structure is also provided.
