  • Patent number: 9873942
    Abstract: Methods of vapor deposition include multiple vapor sources. A vapor deposition method includes delivering pulses of a vapor containing a first source chemical to a reaction space from at least two separate source vessels simultaneously. The pulses can contain a substantially consistent concentration of the first source chemical. The method can include purging the reaction space of an excess of the first source chemical after the delivering, and delivering pulses of a vapor containing a second source chemical to the reaction space from at least two separate source vessels simultaneously after the purging.

  • Publication number: 20160097121
    Abstract: A vapor deposition method and apparatus including at least two vessels containing a same first source chemical. A controller is programmed to simultaneously pulse to the reaction space doses or pulses of a gas from the vessels, each of the doses having a substantially consistent concentration of the first source chemical. The apparatus may also include at least two vessels containing a same second source chemical. The controller can be programmed to simultaneously pulse to the reaction space doses or pulses of a gas from the vessels containing the second source chemical, each of the doses having a substantially consistent concentration of the second source chemical. The second source chemical can be pulsed to the reaction space after the reaction space is purged of an excess of the first source chemical.

  • Patent number: 9139906
    Abstract: Methods for doping a substrate surface or the interface between two thin films by atomic layer deposition process (ALD) are provided. By blocking some of the available binding sites for a dopant precursor with a blocking reactant, the concentration and uniformity of dopant deposited can be controlled. The blocking reactant may be introduced prior to introduction of the dopant precursor in the ALD process, or the blocking reactant and the dopant precursor can be introduced simultaneously.

  • Patent number: 8883270
    Abstract: Systems and methods are delineated which, among other things, are for depositing a film on a substrate that is within a reaction chamber. In an exemplary method, the method may comprise applying an atomic layer deposition cycle to the substrate, wherein the cycle may comprise exposing the substrate to a precursor gas for a precursor pulse interval and then removing the precursor gas thereafter, and exposing the substrate to an oxidizer comprising an oxidant gas and a nitrogen-containing species gas for an oxidation pulse interval and then removing the oxidizer thereafter. Aspects of the present invention utilize molecular and excited nitrogen-oxygen radical/ionic species in possible further combination with oxidizers such as ozone. Embodiments of the present invention also include electronic components and systems that include devices fabricated with methods consistent with the present invention.

  • Patent number: 8563444
    Abstract: Methods for forming metal silicate films are provided. The methods comprise contacting a substrate with alternating and sequential vapor phase pulses of a silicon source chemical, metal source chemical, and an oxidizing agent, wherein the metal source chemical is the next reactant provided after the silicon source chemical. Methods according to some embodiments can be used to form silicon-rich hafnium silicate and zirconium silicate films with substantially uniform film coverages on substrate surface.
