    摘要: Methods of forming layers can comprise defining a plurality of discrete site-isolated regions (SIRs) on a substrate, forming a first layer on one of the discrete SIRs, forming a second layer on the first layer, measuring a lattice parameter or an electrical property of the second layer, The process parameters for the formation of the first layer are varied in a combinatorial manner between different discrete SIRs to explore the possible layers that can result in suitable lattice matching for second layer of a desired crystalline structure.

    摘要: Selector devices that can be suitable for memory device applications can have low leakage currents at low voltages to reduce sneak current paths for non selected devices, and high leakage currents at high voltages to minimize voltage drops during device switching. In some embodiments, the selector device can include a first electrode, a tri-layer dielectric layer, and a second electrode. The tri-layer dielectric layer can include a high leakage dielectric layer sandwiched between two lower leakage dielectric layers. The low leakage layers can function to restrict the current flow across the selector device at low voltages. The high leakage dielectric layer can function to enhance the current flow across the selector device at high voltages.

    摘要: This disclosure provides (a) methods of making an oxide layer (e.g., a dielectric layer) based on titanium oxide, to suppress the formation of anatase-phase titanium oxide and (b) related devices and structures. A metal-insulator-metal (“MIM”) stack is formed using an ozone pretreatment process of a bottom electrode (or other substrate) followed by an ALD process to form a TiO2 dielectric, rooted in the use of an amide-containing precursor. Following the ALD process, an oxidizing anneal process is applied in a manner is hot enough to heal defects in the TiO2 dielectric and reduce interface states between TiO2 and electrode; the anneal temperature is selected so as to not be so hot as to disrupt BEL surface roughness. Further process variants may include doping the titanium oxide, pedestal heating during the ALD process to 275-300 degrees Celsius, use of platinum or ruthenium for the BEL, and plural reagent pulses of ozone for each ALD process cycle. The process provides high deposition rates, and the resulting MIM structure has substantially no x-ray diffraction peaks associated with anatase-phase titanium oxide.

    摘要: In embodiments of the current invention, methods of combinatorial processing and a test chip for use in these methods are described. These methods and test chips enable the efficient development of materials, processes, and process sequence integration schemes for semiconductor manufacturing processes. In general, the methods simplify the processing sequence of forming devices or partially formed devices on a test chip such that the devices can be tested immediately after formation. The immediate testing allows for the high throughput testing of varied materials, processes, or process sequences on the test chip. The test chip has multiple site isolated regions where each of the regions is varied from one another and the test chip is designed to enable high throughput testing of the different regions.
