    Abstract: A method for forming an SiCN film on target substrates placed in a process field inside a process container repeats a unit cycle a plurality of times to laminate thin films respectively formed, thereby forming the SiCN film with a predetermined thickness. The unit cycle includes performing and suspending supply of a silicon source gas, a nitriding gas, and a carbon hydride gas respectively from first, second, and third gas distribution nozzles to the process field. The unit cycle does not turn any one of the gases into plasma but heats the process field to a set temperature of 300 to 700° C. with the supply of the carbon hydride gas performed for a time period in total longer than that of the supply of the silicon source gas, so as to provide the SiCN film with a carbon concentration of 15.2% to 28.5%.

  • Patent number: 8591990
    Abstract: An arrangement of elongated nanowires that include titanium silicide or tungsten silicide may be grown on the exterior surfaces of many individual electrically conductive microfibers of much larger diameter. Each of the nanowires is structurally defined by an elongated, centralized titanium silicide or tungsten silicide nanocore that terminates in a distally spaced gold particle and which is co-axially surrounded by a removable amorphous nanoshell. A gold-directed catalytic growth mechanism initiated during a low pressure chemical vapor deposition process is used to grow the nanowires uniformly along the entire length and circumference of the electrically conductive microfibers where growth is intended. The titanium silicide- or tungsten silicide-based nanowires can be used in a variety electrical, electrochemical, and semiconductor applications.

  • Publication number: 20130040055
    Abstract: In a surface processing method for processing a surface of a member made of silicon carbide (SiC) and having a fragmental layer on a surface thereof, the surface of the member having the fragmental layer is modified into a dense layer to reduce the number of particles generated from the surface of the member when the member is applied to a plasma processing apparatus. Here, the SiC of the surface of the member is recrystallized by heating the fragmental layer.

  • Patent number: 8360001
    Abstract: Chemical vapor deposition processes utilize chemical precursors that allow for the deposition of thin films to be conducted at or near the mass transport limited regime. The processes have high deposition rates yet produce more uniform films, both compositionally and in thickness, than films prepared using conventional chemical precursors. In preferred embodiments, a higher order silane is employed to deposit thin films containing silicon that are useful in the semiconductor industry in various applications such as transistor gate electrodes.
