Abstract: Disclosed are methods of forming PN junction structures, methods of fabricating semiconductor devices using the same, and semiconductor devices fabricated by the same. The method of forming a PN junction structure includes: forming on a substrate a first material layer that includes first transition metal atoms and first chalcogen atoms, loading the first material layer into a process chamber and supplying a gas of second chalcogen atoms, and forming a second material layer by substituting the second chalcogen atoms for the first chalcogen atoms on a selected portion of the first material layer. The first material layer has one of n-type conductivity and p-type conductivity. The second material layer has the other of the n-type conductivity and the p-type conductivity.

Abstract: In a method of manufacturing a semiconductor device, a first insulation layer and a first sacrificial layer are alternately and repeatedly formed on a substrate to form a mold layer. A sacrificial layer structure is formed on the mold layer to include an etch stop layer and a second sacrificial layer sequentially stacked. After forming a hard mask on the sacrificial layer structure, the sacrificial layer structure and the mold layer are etched by a dry etching process using the hard mask as an etching mask to form a channel hole exposing an upper surface of the substrate and form a recess on a sidewall of the second sacrificial layer adjacent to the channel hole. A memory channel structure is formed in the channel hole. The first sacrificial layer is replaced with a gate electrode.
