摘要:
Memory devices, such as DRAM memory devices, may include one or more metal layers above a local interconnect of the DRAM memory that make contact to lower gate regions of the memory device. As the size of semiconductor components decreases and circuit densities increase, the density of the metal routing in these upper metal layers becomes increasingly difficult to fabricate. By providing additional metal routing in the lower gate regions that may be coupled to the upper metal layers, the spacing requirements of the upper metal layers may be eased, while maintaining the size of the semiconductor device. In addition, the additional metal routing formed in the gate regions of the memory devices may be disposed parallel to other metal contacts in a strapping configuration, thus reducing a resistance of the metal contacts, such as buried digit lines of a DRAM memory cell.

摘要:
Metallic coatings and alloys are deposited by thermally reducing inorganic or organic salts containing one or more metals and/or other cationic species in a reducing atmosphere at elevated temperatures. This environmentally-friendly deposition process enables a wide variety of metal and metal alloy compositions to be formed, including metallic or alloy deposits that could not otherwise be electroplated out of water-based solutions. This thermal reduction process and the deposits produced thereof can be applied onto flat strips, sheets, or plates for subsequent fabrication into components and devices and or onto formed parts as intermediate or final surface treatments, particularly components such as battery cans.
摘要:
This invention is for the protection and surface treatment of aluminum, aluminum alloys and coated aluminum substrates against corrosion. The aluminum substrates are treated with an acidic aqueous solution containing small but effective amounts of at least one trivalent chromium salt such as a trivalent chromium sulfate, at least one alkali metal hexafluorazirconate such as potassium hexafluorozirconate in combination with small but effective amounts of at least one water soluble or dispersible thickening agent such as a cellulose compound and at least one water soluble surfactant. The corrosion resistant aluminum substrates of this invention have improved adhesion for overlaying coatings e.g. paints and a lower electrical resistance contact.
