摘要:
A method for fabricating a semiconductor device includes forming a plurality of bodies that are each isolated from another by a trench and each include a diffusion barrier region with a sidewall exposed to the trench, forming a doped layer gap-filling the trench, forming a sidewall junction at the exposed sidewall of the diffusion barrier region by annealing the doped layer, and forming a conductive line coupled with the sidewall junction to fill the trench.

A semiconductor device includes: a punch stop region formed in a substrate; a plurality of buried bit lines formed over the substrate; a plurality of pillar structures formed over the buried bit lines; a plurality of word lines extending to intersect the buried bit lines and being in contact with the pillar structures; and an isolation layer isolating the word lines from the buried bit lines.

A method for fabricating a semiconductor device includes forming a structure having first surfaces at a height above a second surface, which is provided between the first surfaces, forming a first silicon layer on the structure, performing a tilt ion implantation process on the first silicon layer to form a crystalline region and an amorphous region, forming a second silicon layer on the amorphous region, removing the second silicon layer and the first silicon layer until a part of the second surface is exposed, thereby forming an etch barrier, and etching using the etch barrier to form an open part that exposes a part of a sidewall of the structure.

A method for fabricating a semiconductor device includes ion-implanting germanium into a monocrystalline silicon-containing substrate; forming a gate oxide layer over a surface of the monocrystalline silicon-containing substrate and forming, under the gate oxide layer, a germanium-rich region in which the germanium is concentrated, by performing a plasma oxidation process; and crystallizing the germanium-rich region by performing an annealing process.
