A method for forming a semiconductor device structure is provided. The method includes providing a substrate having a base, a first fin, and a second fin over the base. The method includes forming a gate stack over the first fin and the second fin. The method includes forming a first spacer over gate sidewalls of the gate stack and a second spacer adjacent to the second fin. The method includes partially removing the first fin and the second fin. The method includes forming a first source/drain structure and a second source/drain structure in the first trench and the second trench respectively. A first ratio of a first height of the first merged portion to a second height of a first top surface of the first source/drain structure is greater than or equal to about 0.5.

Semiconductor device structure with source/drain structure and method for forming the same

A method includes forming a gate structure on a substrate; forming a gate spacer on a sidewall of the gate structure; forming a carbon-containing layer on the gate spacer; diffusing carbon from the carbon-containing layer into a portion of the substrate below the gate spacer; forming a recess in the substrate on one side of the gate spacer opposite to the gate structure; and forming an epitaxy feature in the recess of the substrate.

Semiconductor device and manufacturing method thereof

A finFET device and methods of forming a finFET device are provided. The method includes depositing a dummy gate over and along sidewalls of a fin extending upwards from a semiconductor substrate, forming a first gate spacer along a sidewall of the dummy gate, and plasma-doping the first gate spacer with carbon to form a carbon-doped gate spacer. The method further includes forming a source/drain region adjacent a channel region of the fin and diffusing carbon from the carbon-doped gate spacer into a first region of the fin to provide a first carbon-doped region. The first carbon-doped region is disposed between at least a portion of the source/drain region and the channel region of the fin.
