Abstract:
The present disclosure relates to the technical field of semiconductors, and discloses a semiconductor device and a manufacturing method therefor. The semiconductor device includes: a semiconductor substrate; a semiconductor fin on the semiconductor substrate; a gate structure on the semiconductor fin; a first recess and a second recess in the semiconductor fin and respectively at two sides of the gate structure; a diffusion barrier layer located at a bottom portion and a side wall of at least one recess of the first recess and the second recess; and an electrode on the diffusion barrier layer. In forms of the present disclosure, a diffusion barrier layer is formed on a bottom portion and a side wall of a recess of a semiconductor device; an electrode is formed on the diffusion barrier layer; and the diffusion barrier layer may possibly reduce a possibility that P-typed dopants or N-typed dopants in the electrode are diffused to a channel region, so as to possibly avoid decreasing a charge carrier mobility of the channel region, and improve the SCE, thereby improving performance of the device.

Claim (Index 17):
The method according to  claim 16 , wherein the step of forming the diffusion barrier layer at the bottom portions and the side walls of the first recess and the second recess comprises:\n forming, by means of an epitaxial process, the first diffusion barrier layer at the bottom portions and the side walls of the first recess and the second recess, and forming, by means of the epitaxial process, the second diffusion barrier layer on the first diffusion barrier layer; or forming, by means of the epitaxial process, the second diffusion barrier layer at the bottom portions and the side walls of the first recess and the second recess, and forming, by means of the epitaxial process, the first diffusion barrier layer on the second diffusion barrier layer.
