    摘要: A SONOS type non-volatile memory device includes a substrate having source/drain regions doped with impurities and a channel region between the source/drain regions. A tunnel insulation layer including silicon oxide is formed on the channel region of the substrate. A charge-trapping insulation layer including silicon nitride is formed on the tunnel insulation layer. A blocking insulation layer is formed on the charge-trapping insulation layer. The blocking insulation layer has a laminate layered structure in which a plurality of layers, at least one of which includes a metal oxide layer, are sequentially stacked. An electrode is formed on the blocking insulation layer.

    摘要: A thin film structure is formed that includes hafnium silicon oxide using an atomic layer deposition process. A first reactant including tetrakis ethyl methyl amino hafnium (TEMAH) is introduced onto a substrate. A first portion of the first reactant is chemisorbed to the substrate, whereas a second portion of the first reactant is physorbed to the first portion of the first reactant. A first oxidant is provided onto the substrate. A first thin film including hafnium oxide is formed on the substrate by chemically reacting the first oxidant with the first portion of the first reactant. A second reactant including amino propyl tri ethoxy silane (APTES) is introduced onto the first thin film. A first portion of the second reactant is chemisorbed to the first thin film, whereas a second portion of the second reactant is physorbed to the first portion of the second reactant. A second oxidant is provided onto the first thin film. A second thin film including silicon oxide is formed on the first thin film by chemically reacting the second oxidant with the first portion of the second reactant.

    摘要: Example embodiments relate to a metal-oxide-semiconductor (MOS) transistor and a method of manufacturing the MOS transistor. In a MOS transistor and a method of manufacturing the same, a gate insulation layer may be formed on the channel region of the substrate, and may further include metal oxide or metal silicate. A buffer layer may be formed on the gate insulation layer. The buffer layer may further include any one selected from the group including silicon nitride, aluminum nitride, undoped polysilicon and combinations thereof. A gate conductive layer may be formed on the buffer layer and may further include polysilicon. The buffer layer may retard or prevent a reaction between the gate conductive layer and the gate insulation layer. Source/drain regions may be further formed at surface portions of the substrate and doped with impurities. A channel region may also be further formed at the surface portion of the substrate between the source/drain regions.
