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 19):
The method according to  claim 16 , wherein:\n a thickness range of the diffusion barrier layer is from 8 nm to 35 nm; a thickness range of the first diffusion barrier layer is from 4 nm to 16 nm; and a thickness range of the second diffusion barrier layer is from 4 nm to 16 nm.
