    摘要: Films are deposited on a substrate by a process in which atomic layer deposition (ALD) is used to deposit one layer of the film and pulsed chemical vapor deposition (CVD) is used to deposit another layer of the film. During the ALD part of the process, a layer is formed by flowing sequential and alternating pulses of mutually reactive reactants that deposit self-limitingly on a substrate. During the pulsed CVD part of the process, another layer is deposited by flowing two CVD reactants into a reaction chamber, with at least a first of the CVD reactants flowed into the reaction chamber in pulses, with those pulses overlapping at least partially with the flow of a second of the CVD reactants. The ALD and CVD parts of the process ca be used to deposit layers with different compositions, thereby forming, e.g., nanolaminate films. Preferably, high quality layers are formed by flowing the second CVD reactant into the reaction chamber for a longer total duration than the first CVD reactant. In some embodiments, the pulses of the third reactant at separated by a duration at least about 1.75 times the length of the pulse. Preferably, less than about 8 monolayers of material are deposited per pulse of the first CVD reactant.

    摘要: Methods of forming a roughened metal surface on a substrate are provided, along with structures comprising such roughened surfaces. 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 be used, for example, in the manufacture of integrated circuits.

    摘要: The invention relates generally to processes for enhancing the deposition of noble metal thin films on a substrate by atomic layer deposition. Treatment with gaseous halides or metalorganic compounds reduces the incubation time for deposition of noble metals on particular surfaces. The methods may be utilized to facilitate selective deposition. For example, selective deposition of noble metals on high-k materials relative to insulators can be enhanced by pretreatment with halide reactants. In addition, halide treatment can be used to avoid deposition on the quartz walls of the reaction chamber.

    摘要: Germanium has higher mobility than silicon and therefore is considered to be a good alternative semiconductor for CMOS technology. Surface treatments a can facilitate atomic layer deposition (ALD) of thin films, such as high-k dielectric layers, on germanium substrates. Surface treatment can comprise the formation of a thin layer of GeOx or GeOxNy. After surface treatment and prior to deposition of the desired thin film, a passivation layer may be deposited on the substrate. The passivation layer may be, for example, a metal oxide layer deposited by ALD.
