Abstract: A method for fabricating semiconductor device with fin-shaped structure is disclosed. The method includes the steps of: forming a fin-shaped structure on a substrate; forming a first dielectric layer on the substrate and the fin-shaped structure; depositing a second dielectric layer on the first dielectric layer; etching back a portion of the second dielectric layer; removing part of the first dielectric layer to expose a top surface and part of the sidewall of the fin-shaped structure; forming an epitaxial layer to cover the exposed top surface and part of the sidewall of the fin-shaped structure; and removing a portion of the second dielectric layer.

Abstract: A method for manufacturing a semiconductor device and a device manufactured using the same are provided. According to the embodiment, substrate with a dielectric layer formed thereon is provided. Plural trenches are defined in the dielectric layer, and the trenches are isolated by the dielectric layer. A first barrier layer is formed in the trenches as barrier liners of the trenches, followed by filling the trenches with a conductor. Then, the conductor in the trenches is partially removed to form a plurality of recesses, wherein remained conductor has a flat surface. Next, a second barrier layer is formed in the recesses as barrier caps of the trenches.
