Abstract
The present application discloses a semiconductor device structure and a method for manufacturing the same, wherein the method comprises: forming a semiconductor substrate comprising a local SOI structure having a local buried isolation dielectric layer; forming a fin on the silicon substrate on top of the local buried isolation dielectric layer; forming a gate stack structure on the top and side faces of the fin; forming source/drain structures in the fin on both sides of the gate stack structure; and performing metallization. The present invention makes use of traditional quasi-planar based top-down processes, thus the manufacturing process thereof is simple to implement; the present invention exhibits good compatibility with CMOS planar process and can be easily integrated, therefore, short channel effects are suppressed desirably, and MOSFETs are boosted to develop towards a trend of downscaling size.
