  • Publication number: 20150099066
    Abstract: The present invention relates generally to methods and apparatus for the controlled growing of material on substrates. According to embodiments of the present invention, a precursor feed is controlled in order to provide an optimal pulse profile. This may be accomplished by splitting the feed into two paths. One of the paths is restricted in a continuous manner. The other path is restricted in a periodic manner. The output of the two paths converges at a point prior to entry of the reactor. Therefore, a single precursor source is able to fed precursor in to a reactor under two different conditions, one which can be seen as mimicking ALD conditions and one which can be seen as mimicking CVD conditions. This allows for an otherwise single mode reactor to be operated in a plurality of modes including one or more ALD/CVD combination modes. Additionally, the pulse profile of each pulse can be modified.

  • Patent number: 8927403
    Abstract: Processes are provided for selectively depositing thin films comprising one or more noble metals on a substrate by vapor deposition processes. In some embodiments, atomic layer deposition (ALD) processes are used to deposit a noble metal containing thin film on a high-k material, metal, metal nitride or other conductive metal compound while avoiding deposition on a lower k insulator such as silicon oxide. The ability to deposit on a first surface, such as a high-k material, while avoiding deposition on a second surface, such as a silicon oxide or silicon nitride surface, may be utilized, for example, in the formation of a gate electrode.

  • Patent number: 8592294
    Abstract: Methods are provided herein for forming metal oxide thin films by atomic layer deposition. The metal oxide thin films can be deposited at high temperatures such that the thin film is crystalline as deposited. The metal oxide thin films can be used, for example, as dielectric oxides in transistors, flash devices, capacitors, integrated circuits, and other semiconductor applications.

  • Patent number: 8545936
    Abstract: Methods of forming a roughened metal surface on a substrate for nucleating carbon nanotube growth, and subsequently growing carbon nanotubes are provided. In preferred embodiments roughened surfaces are formed by selectively depositing metal or metal oxide on a substrate surface to form discrete, three-dimensional islands. Selective deposition may be obtained, for example, by modifying process conditions to cause metal agglomeration or by treating the substrate surface to provide a limited number of discontinuous reactive sites. The roughened metal surface may then be used as nucleation points for initiating carbon nanotube growth. The carbon nanotubes are grown in the same process chamber (in-situ) as the formation of the three dimensional metal islands without exposing the substrate to air.

  • Patent number: 7476618
    Abstract: A method for enhancing the reliability of copper interconnects and/or contacts, such as the bottom of vias exposing top surfaces of buried copper, or at the top of copper lines just after CMP. The method comprises contacting the exposed copper surface with a vapor phase compound of a noble metal and selectively forming a layer of the noble metal on the exposed copper surface, either by a copper replacement reaction or selective deposition (e.g., ALD or CVD) of the noble metal.
