Abstract:
Provided are semiconductor devices, such as resistive random access memory (ReRAM) cells, that include current limiting layers formed from doped metal oxides and/or nitrides. These current limiting layers may have resistivities of at least about 1 Ohm-cm. This resistivity level is maintained even when the layers are subjected to strong electrical fields and/or high temperature annealing. In some embodiments, the breakdown voltage of a current limiting layer may be at least about 8V. Some examples of such current limiting layers include titanium oxide doped with niobium, tin oxide doped with antimony, and zinc oxide doped with aluminum. Dopants and base materials may be deposited as separate sub-layers and then redistributed by annealing or may be co-deposited using reactive sputtering or co-sputtering. The high resistivity of the layers allows scaling down the size of the semiconductor devices including these layer while maintaining their performance.
Abstract:
A switching element for resistive-switching memory (ReRAM) provides a controllable, consistent filament break-point at an abrupt structural discontinuity between a layer of high-k high-ionicity variable-resistance (VR) material and a layer of low-k low-ionicity VR material. The high-ionicity layer may be crystalline and the low-ionicity layer may be amorphous. The consistent break-point and characteristics of the low-ionicity layer facilitate lower-power operation. The defects (e.g., oxygen or nitrogen vacancies) that constitute the filament originate either in the high-ionicity VR layer or in a source electrode. The electrode nearest to the low-ionicity layer may be intrinsically inert or may be rendered effectively inert. Some electrodes are rendered effectively inert by the creation of the low-ionicity layer over the electrode.

The diffusion barrier comprises a self-assembled monolayer (SAM) on a semiconductor substrate, where one surface of the SAM is disposed in contact with and covalently bonded to the semiconductor substrate, and one surface of the monolayer is disposed in contact with and covalently bonded to a metal layer.

In some embodiments, (CnHy) can be branched, crosslinked, or cyclic.

Abstract:
Epitaxial films are grown by alternately exposed to precursor dosing regions, inert gas plasma regions, hydrogen-containing plasma regions, chlorine-containing plasma and metrology regions, or regions where an atomic hydrogen source is located. Alternately, laser irradiation techniques may be substituted for the plasma energy in some of the processing regions. The film growth process can be implemented at substrate temperatures between about 25 C and about 600 C, together with optional exposures to laser irradiation to cause the surface of the film to melt or to experience a near-melt condition.
Abstract:
Forming a resistive memory structure at a temperature well above the operating temperature can reduce the forming voltage and create a defect distribution with higher stability and lower programming voltages. The forming temperature can be up to 200 C above the operating temperature. The memory chip can include an embedded heater in the chip package, allowing for a chip forming process after packaging.

Combinatorial processing of a substrate comprising site-isolated sputter deposition and site-isolated plasma processing can be performed in a same process chamber. The process chamber, configured to perform sputter deposition and plasma processing, comprises a grounded shield having at least an aperture disposed above the substrate to form a small, dark space gap to reduce or eliminate any plasma formation within the gap. The plasma processing may include plasma etching or plasma surface treatment.

Abstract:
A doped fullerene-based conductive material can be used as an electrode, which can contact a dielectric such as a high k dielectric. By aligning the dielectric with the band gap of the doped fullerene-based electrode, e.g., the conduction band minimum of the dielectric falls into one of the band gaps of the doped fullerene-based material, thermionic leakage through the dielectric can be reduced, since the excited electrons or holes in the electrode would need higher thermal excitation energy to overcome the band gap before passing through the dielectric layer.
