    摘要: Some embodiments include electrical interconnects. The interconnects may contain laminate structures having a graphene region sandwiched between non-graphene regions. In some embodiments the graphene and non-graphene regions may be nested within one another. In some embodiments an electrically insulative material may be over an upper surface of the laminate structure, and an opening may extend through the insulative material to a portion of the laminate structure. Electrically conductive material may be within the opening and in electrical contact with at least one of the non-graphene regions of the laminate structure. Some embodiments include methods of forming electrical interconnects in which non-graphene material and graphene are alternately formed within a trench to form nested non-graphene and graphene regions.

    摘要: Methods of forming magnetic memory cells are disclosed. Magnetic and non-magnetic materials are formed into a primal precursor structure in an initial stress state of essentially no strain, compressive strain, or tensile strain. A stress-compensating material, e.g., a non-sacrificial, conductive material, is formed to be disposed on the primal precursor structure to form a stress-compensated precursor structure in a net beneficial stress state. Thereafter, the stress-compensated precursor structure may be patterned to form a cell core of a memory cell. The net beneficial stress state of the stress-compensated precursor structure lends to formation of one or more magnetic regions, in the cell core, exhibiting a vertical magnetic orientation without deteriorating a magnetic strength of the one or more magnetic regions. Also disclosed are memory cells, memory cell structures, semiconductor device structures, and spin torque transfer magnetic random access memory (STT-MRAM) systems.

    摘要: A method of high aspect ratio contact etching a substantially vertical contact hole in an oxide layer using a hard photoresist mask is described. The oxide layer is deposited on an underlying substrate. A plasma etching gas is formed from a carbon source gas. Dopants are mixed into the gas. The doped plasma etching gas etches a substantially vertical contact hole through the oxide layer by doping carbon chain polymers formed along the sidewalls of the contact holes during the etching process into a conductive state. The conductive state of the carbon chain polymers reduces the charge buildup along sidewalls to prevent twisting of the contact holes by bleeding off the charge and ensuring proper alignment with active area landing regions. The etching stops at the underlying substrate.

    摘要: Methods and structures are described for reducing leakage currents in semiconductor memory storage cells. Vertically oriented nanorods may be used in the channel region of an access transistor. The nanorod diameter can be made small enough to cause an increase in the electronic band gap energy in the channel region of the access transistor, which may serve to limit channel leakage currents in its off-state. In various embodiments, the access transistor may be electrically coupled to a double-sided capacitor. Memory devices according to embodiments of the invention, and systems including such devices are also disclosed.
