    摘要: Semiconductor contact structures extend through a dielectric material and provide contact to multiple different subjacent materials including a silicide material and a non-silicide material such as doped silicon. The contact structures includes a lower composite layer formed using a multi-step ionized metal plasma (IMP) deposition operation. A lower IMP film is formed at a high AC bias power followed by the formation of an upper IMP film at a lower AC bias power. The composite layer may be formed of titanium. A further layer is formed as a liner over the composite layer and the liner layer may advantageously be formed using CVD and may be TiN. A conductive plug material such as tungsten or copper fills the contact openings.

    摘要: The present disclosure, in some embodiments, relates to a method of forming a resistive random access memory (RRAM) device. The method includes forming one or more bottom electrode films over a lower interconnect layer within a lower inter-level dielectric layer. A data storage film having a variable resistance is formed above the one or more bottom electrode films. A lower top electrode film including a metal is over the data storage film, one or more oxygen barrier films are over the lower top electrode film, and an upper top electrode film including a metal nitride is formed over the one or more oxygen barrier films. The one or more oxygen barrier films include one or more of a metal oxide film and a metal oxynitride film. The upper top electrode film is formed to be completely confined over a top surface of the one or more oxygen barrier films.
