  • Publication number: 20080038524
    Abstract: The invention relates to a method of selective doping of a material by a) radiating a predetermined pre-treated pattern/region into the material, b) treating the material for producing reactive groups in the pre-treated pattern/region, and c) doping the material by the atomic layer deposition method for producing a pattern/region doped with a dopant in the material. The invention further relates to a selectively doped material, a system for preparing a selectively doped material, and use of said method.

  • Publication number: 20080014762
    Abstract: This invention concerns a process for producing oxide thin film on a substrate by an ALD type process. According to the process, alternating vapour-phase pulses of at least one metal source material, and at least one oxygen source material are fed into a reaction space and contacted with the substrate. According to the invention, an yttrium source material and a zirconium source material are alternately used as the metal source material so as to form an yttrium-stabilised zirconium oxide (YSZ) thin film on a substrate.

  • Publication number: 20070218290
    Abstract: The invention relates to a method for doping material, the method being characterized by depositing at least one dopant deposition layer or a part thereof on the surface of the material and/or on a surface of a part or parts thereof with the atom layer deposition (ALD) method, and further processing the material coated with a dopant in such a manner that the original structure of the dopant layer is changed to obtain new properties for the doped material. The material to be doped is preferably glass, ceramic, polymer, metal, or a composite material made thereof, and the further processing of the material coated with the dopant is a mechanical, chemical, radiation, or heat treatment, whereby the aim is to change the refraction index, absorbing power, electrical and/or heat conductivity, colour, or mechanical or chemical durability of the doped material.

  • Publication number: 20060088660
    Abstract: Lead containing oxide thin films by Atomic Layer Deposition, comprising using a metal-organic lead compound, having organic ligands bonded to a lead atom by carbon-lead bonds, as a source material for the lead oxide. Stoichiometric PbTiO3 thin films with excellent uniformity can be deposited on substrates by ALD growth using, for example, Ph4Pb, O3, Ti(OiPr)4 and H2O as precursors at 250 and 300° C.

  • Patent number: 6858546
    Abstract: The present invention concerns a process for depositing rare earth oxide thin films, especially yttrium, lanthanum and gadolinium oxide thin films by an ALD process, according to which invention the source chemicals are cyclopentadienyl compounds of rare earth metals, especially those of yttrium, lanthanum and gadolinium. Suitable deposition temperatures for yttrium oxide are between 200 and 400° C. when the deposition pressure is between 1 and 50 mbar. Most suitable deposition temperatures for lanthanum oxide are between 160 and 165° C. when the deposition pressure is between 1 and 50 mbar.
