SUBSTRATE PROCESSING METHOD AND RECORDING MEDIUM
A substrate processing method is for forming a metal film on a target substrate by using a plasma. The method includes loading a target substrate having a silicon-containing layer on a surface thereof into a processing chamber which is pre-coated by a film containing a metal, introducing hydrogen gas and a gaseous compound of the metal and halogen into the processing chamber, generating a plasma, and forming a metal film on the target substrate. The method further includes performing a first reduction process of forming an atmosphere of a plasma obtained by activating hydrogen gas in the processing chamber, unloading the target substrate from the processing chamber, performing a second reduction process of forming an atmosphere of a plasma obtained by activating hydrogen gas in the processing chamber, and loading a next target substrate into the processing chamber.
Conformal doped amorphous silicon as nucleation layer for metal deposition
Methods for depositing a metal film on a doped amorphous silicon layer as a nucleation layer and/or a glue layer on a substrate. Some embodiments further comprise the incorporation of a glue layer to increase the ability of the doped amorphous silicon layer and metal layer to stick to the substrate.
Methods of manufacturing semiconductor devices and apparatuses for manufacturing the same
A method of manufacturing a semiconductor device may include forming a stack structure by alternately stacking sacrificial layers and interlayer insulating layers on a substrate, forming channel structures extending through the stack structure, forming openings extending through the stack structure, forming lateral openings by removing the sacrificial layers exposed by the openings, and forming gate electrodes in the lateral openings. Forming the gate electrodes may include supplying a source gas containing tungsten (W) wherein the source gas is heated to a first temperature and is supplied in a deposition apparatus at the first temperature, supplying a reactant gas containing hydrogen (H) subsequently to supplying the source gas, wherein the reactant gas is heated to a second temperature and is supplied in the deposition apparatus at the second temperature, and supplying a purge gas subsequently to supplying the reactant gas.

Corrosion-resistant diffusion coatings
A metal article such as a gas turbine component may include a super-diffusion coating with unusually high content of the desired constituent. The coating may be provided by combining two or more diffusion coating processes, each process interdiffusing the desired constituent with the metal article from a different metal source. The metal article can be placed in physical contact with a metal source in powder form as a first source, and the article can also be exposed an additional metal vapor source. Super-chromide coatings can be produced with alpha-chrome content in a manner that also provides the coating with sufficient ductility for long-term durability. For example, a shank portion of a gas turbine blade may be provided with a chromide coating with at least a portion of the coating having from 60-90% chromium content.
