  • Patent number: 6723186
    Abstract: A method of manufacturing a metallic film consisting of giant single crystal grains is disclosed. The method includes depositing the metallic film on a substrate under an atmosphere of an inert gas and a specified additive gas to change a surface energy, grain boundary energy, or internal strain energy of the metallic film. The method also includes annealing step of the resultant of the deposition at a temperature suitable for the grain growth of the metallic film containing the additive gases. According to the method, the metallic film consisting of giant single crystal grains having a grain size whose ratio of thickness to an average grain size of the film is above 50 can be produced without depending upon the kind of substrate and deposition method.

  • Patent number: 6498097
    Abstract: A platinum film orientation-controlled to (111), (200) and/or (220) is provided by depositing the platinum film under an atmosphere containing an oxygen component such as O2, O3, N2O , N2+O2, or mixtures thereof as well as an inert gas (Ar, Ne, Kr, or Xe) on a substrate heated to a temperature ranged from room temperature to 700° C., and annealing to remove the gases introduced into the platinum film during the deposition thereof. The platinum film formed in this process has excellent electrical conductivity (resistivity is lower than 15 &mgr;&OHgr;-cm), good enough adhesion strength to be used for electronic devices, and does not show hillocks, voids or pinholes.

  • Patent number: 6312567
    Abstract: A method of depositing a (200)-oriented platinum thin film on a substrate, including the steps of forming a oxygen containing platinum layer on the surface of a silicon wafer heated to a temperature range over room temperature and not exceeding 700° C. under a mixed gaseous atmosphere of oxygen and inert gas and annealing the substrate at a temperature between 400° C. and 1000° C. The platinum thin film formed according to the present invention in (200)-oriented and does not have any conventional defects such as hillocks or voids.

  • Patent number: 6054331
    Abstract: A platinum film, which is used as a bottom electrode for a capacitor in a DRAM cell or a non-volatile ferroelectric memory cell, is formed in two separate processes, wherein a first thickness platinum part thereof is deposited under an inert gas atmosphere, and the second thickness platinum part is deposited under an atmosphere containing oxygen, nitrogen and/or a mixture thereof as well as an inert gas. The platinum film is annealed under a vacuum atmosphere to remove the oxygen an/or nitrogen introduced during the deposition of the second thickness platinum part. The annealed platinum film prevents formation of an oxide on a functional intermediate film such as a diffusion barrier layer or an adhesion layer, which is provided below the bottom electrode of platinum film.

  • Patent number: 6025205
    Abstract: Platinum film orientation-controlled to (111), (200) and/or (220) are provided by depositing the platinum film under an atmosphere containing nitrogen as well as an inert gas (Ar, Ne, Kr, Xe) on a substrate heated to temperature ranged from room temperature to 500.degree. C., and then annealing to substantially remove nitrogen introduced into the platinum film during the deposition thereof. The platinum film formed in this process has an excellent electrical conductivity (resistivity is lower than 15 .mu..OMEGA.-cm), good enough adhesion strength to be used for electronic devices, and does not show hillocks, pores or pinholes.

  • Patent number: 5981390
    Abstract: The present invention relates to a method of depositing a platinum thin-film on a silicon wafer. The method includes the steps of depositing a platinum layer on an insulating oxide layer under an oxidation atmosphere to form a mixture film consisted of platinum grains, platinum oxide grains and oxygen adhered to those grains (hereinafter, "the mixture film" to be referred as "oxygen containing platinum thin-film"); depositing an additional platinum thin-film to a desired thickness on the oxygen containing platinum thin-film under a complete inert atmosphere; and annealing the silicon substrate at a temperature of 400 to 1,300.degree. C. in order to remove oxygen present in the independent form or in platinum oxide form within the oxygen containing platinum thin-film and to stabilize the entire platinum thin-film.
