Nickel is a chemical element with the symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel, powdered to maximize the reactive surface area, shows a significant chemical activity, but larger pieces are slow to react with air under standard conditions because an oxide layer forms on the surface and prevents further corrosion (passivation). Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere.

Deposition of an intermediate catalytic layer on a barrier layer for copper metallization

In one embodiment, a method for depositing a conductive material on a substrate is provided which includes exposing a substrate containing a barrier layer to a volatile reducing precursor to form a reducing layer during a soak process, exposing the reducing layer to a catalytic-metal precursor to deposit a catalytic metal-containing layer on the barrier layer, and depositing a conductive layer (e.g., copper) on the catalytic metal-containing layer. The volatile reducing precursor may include phosphine, diborane, silane, a plasma thereof, or a combination thereof and be exposed to the substrate for a time period within a range from about 1 second to about 30 seconds during the soak process. The catalytic metal-containing layer may contain ruthenium, cobalt, rhodium, iridium, nickel, palladium, platinum, silver, or copper. In one example, the catalytic metal-containing layer is deposited by a vapor deposition process utilizing ruthenium tetroxide formed by an in situ process.

Methods for depositing nickel films and for making nickel silicide and nickel germanide

In one aspect, methods of silicidation and germanidation are provided. In some embodiments, methods for forming metal silicide can include forming a non-oxide interface, such as germanium or solid antimony, over exposed silicon regions of a substrate. Metal oxide is formed over the interface layer. Annealing and reducing causes metal from the metal oxide to react with the underlying silicon and form metal silicide. Additionally, metal germanide can be formed by reduction of metal oxide over germanium, whether or not any underlying silicon is also silicided. In other embodiments, nickel is deposited directly and an interface layer is not used. In another aspect, methods of depositing nickel thin films by vapor phase deposition processes are provided. In some embodiments, nickel thin films are deposited by ALD. Nickel thin films can be used directly in silicidation and germanidation processes.

Method of manufacturing a semiconductor device

A crystal growth 301 is carried out by diffusing a metal element, and a nickel element is moved into regions 108 and 109 which has been doped with phosphorus. An axis coincident with the moving directions 302 and 303 of the nickel element at this time is made to coincide with an axis coincident with the direction of the crystal growth, and a TFT having the regions as channel forming regions is manufactured. In the path of the region where nickel moved, since high crystallinity is obtained in the moving direction, the TFT having high characteristics can be obtained by this way.

The disclosed alloys also have increased nitrogen solubility thereby enhancing strength at all temperatures because nitride precipitates or nitrogen porosity during casting are not observed. The solubility of nitrogen is dramatically enhanced by the presence of manganese, which also retains or improves the solubility of carbon thereby providing additional solid solution strengthening due to the presence of manganese and nitrogen, and combined carbon.

Methods for forming through-wafer interconnects, intermediate structures so formed, and devices and systems having at least one solder dam structure

A method for forming through-wafer interconnects (TWI) in a substrate of a thickness in excess of that of a semiconductor die such as a semiconductor wafer. Blind holes are formed from the active surface, sidewalls thereof passivated and coated with a solder-wetting material.

Method for fabricating a semiconductor device

Concentration of metal element which promotes crystallization of silicon and which exists within a crystalline silicon film obtained by utilizing the metal element is reduced. A first heat treatment for crystallization is performed after introducing nickel to an amorphous silicon film 103. Then, laser light is irradiated to diffuse nickel element which is concentrated locally. After that, another heat treatment is performed within an oxidizing atmosphere at a temperature higher than that of the previous heat treatment. At this time, HCl or the like is added to the atmosphere. A thermal oxide film 106 is formed in this step. At this time, gettering of the nickel element into the thermal oxide film 106 takes place. Then, the thermal oxide film 106 is removed. Thereby, a crystalline silicon film 107 having low concentration of the metal element and a high crystallinity can be obtained.
