摘要: The invention includes methods of forming PMOS transistors and NMOS transistors. The NMOS transistors can be formed to have a thin silicon-containing material between a pair of metal nitride materials, while the PMOS transistors are formed to have the metal nitride materials directly against one another. The invention also includes constructions which contain an NMOS transistor gate stack having a thin silicon-containing material between a pair of metal nitride materials. The silicon-containing material can, for example, consist of silicon, conductively-doped silicon, or silicon oxide; and can have a thickness of less than or equal to about 30 angstroms.

摘要: Some embodiments include methods of forming memory cells. Metal oxide may be deposited over a first electrode, with the deposited metal oxide having a relatively low degree of crystallinity. The degree of crystallinity within the metal oxide may be increased after the deposition of the metal oxide.
