Abstract:
Semiconductor device and fabrication method are provided. The method includes: providing a base substrate with a bottom metallic layer in the base substrate and a dielectric layer on the base substrate; forming interconnect openings through the dielectric layer and exposing the bottom metallic layer, where each interconnect openings includes a contacting hole and a groove on the contacting hole; forming a first conducting layer in the contacting hole, where the first conducting layer is made of a material having a first conductivity along a direction from the bottom metallic layer to a top surface of the first conducting layer; and after forming the first conducting layer, forming a second conducting layer in the groove, where the second conducting layer is made of a material having a second conductivity along a direction parallel to the top surface of the base substrate and the first conductivity is greater than the second conductivity.

Claim (Index 11):
The fabrication method according to  claim 6 , further including:\n before forming the catalytic matrix layer, forming a barrier seed structure on the inner sidewalk of the groove, on the inner sidewalls of the contacting hole, and on the dielectric layer, followed by forming the catalytic matrix layer on the barrier seed structure; and when removing the first portion of the conducting material layer from the dielectric layer, removing the portion of the catalytic matrix layer, the portion of the catalyst layer and a portion of the barrier seed structure on the dielectric layer.
