Abstract:
A semiconductor device includes a first insulating layer (interlayer insulating layer), a resistive element that is disposed over the first insulating layer (interlayer insulating layer) and at least a surface layer of which is a TaSiN layer, and an interlayer insulating layer disposed over the first insulating layer (interlayer insulating layer) and the resistive element. Multiple via plugs having ends coupled to the TaSiN layer are disposed in the interlayer insulating layer.

Abstract:
A semiconductor device containing a novel cyclosiloxane polymer showing electroconductivity or semiconductivity has a charge transport layer comprising a plasma polymer containing structural units (A) each having a transition metal as a central metal and structural units (B) each situated between structural units (A) adjacent to each other and having a cyclosiloxane skeleton. The charge transport layer is formed by plasma polymerization of an organic metal compound having the transition metal as the central metal and the cyclosiloxane compound in a reactor.
Abstract:
Provided is a semiconductor memory device (resistance random access memory element) improved in properties. A Ru film is formed as a film of a lower electrode by sputtering, and a Ta film is formed thereonto by sputtering. Next, the Ta film is oxidized with plasma to oxidize the Ta film. In this way, a compound Ta2O5 is produced and further Ru is diffused into the compound to form a layer (variable resistance layer) in which Ru is diffused into the compound Ta2O5. Such an incorporation of a metal (such as Ru) into a transition metal oxide TMO (such as Ta2O5) makes it possible to form electron conductive paths additional to filaments to lower the filaments in density and thickness. Thus, the memory element can be restrained from undergoing OFF-fixation, by which the element is not easily lowered in resistance, to be improved in ON-properties.
