    Abstract: 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.

    Abstract: A semiconductor device includes a gate structure on a substrate, a single diffusion break (SDB) structure adjacent to the gate structure, a first spacer adjacent to the gate structure, a second spacer adjacent to the SDB structure, a source/drain region between the first spacer and the second spacer, an interlayer dielectric (ILD) layer around the gate structure and the SDB structure, and a contact plug in the ILD layer and on the source/drain region. Preferably, a top surface of the second spacer is lower than a top surface of the first spacer.

    Abstract: 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.

    Abstract: A semiconductor device includes a gate isolation structure on a shallow trench isolation (STI), a first epitaxial layer on one side of the gate isolation structure, a second epitaxial layer on another side of the gate isolation structure, first fin-shaped structures directly under the first epitaxial layer, and second fin-shaped structures directly under the second epitaxial layer, in which the STI surrounds the first fin-shaped structures and the second fin-shaped structures.
