摘要:
A first gate oxide layer pattern having a first thickness is formed in a first region of a substrate and a second gate oxide layer having a second thickness is formed in a second region of a substrate. A surface of the second gate oxide layer is selectively nitrified to form an oxynitride layer, thereby reducing a depletion effect of a poly gate and a fluctuation of threshold voltage.

摘要:
A method of forming a vertical diode and a method of manufacturing a semiconductor device (e.g., a semiconductor memory device such as a phase-change memory device) includes forming an insulating structure having an opening on a substrate and filling the opening with an amorphous silicon layer. A metal silicide layer is formed to contact at least a portion of the amorphous silicon layer and a polysilicon layer is then formed in the opening by crystallizing the amorphous silicon layer using the metal silicide layer. A doped polysilicon layer is formed by implanting impurities into the polysilicon layer. Thus, the polysilicon layer is formed in the opening without performing a selective epitaxial growth (SEG) process, so that electrical characteristics of the diode may be improved.

摘要:
The stacked semiconductor device includes a semiconductor substrate, a multi-layered insulation layer pattern having at least two insulation layer patterns and an opening, an active layer pattern formed on each of the insulation layer patterns, a first plug including single crystalline silicon-germanium, a second plug including single crystalline silicon, and a wiring electrically connected to the first plug and sufficiently filling up the opening. The insulation layer patterns are vertically stacked on the semiconductor substrate and the opening exposes an upper face of the semiconductor substrate. A side portion of the active layer pattern is exposed by the opening. The first plug is formed on the upper face of the semiconductor substrate to partially fill the opening. The second plug is partially formed on the first plug, and has substantially the same interface as that of the first plug.
