  • Publication number: 20150132488
    Abstract: The present invention relates to a graphene pattern forming method using a delamination technique employing a polymer stamp. The technique is adequate for forming a graphene pattern having a an arbitrary target pattern. According to the present invention, a portion of a graphene layer formed on a substrate is physically and selectively delaminated using the polymer stamp to simply and easily form a desired graphene pattern having a uniform line width on the substrate. Also, a portion of the graphene layer formed on the substrate is physically and selectively delaminated in a roll-to-roll manner using a rotating body stamp or by using a stamp having a large area to simply and easily form a desired graphene pattern having a uniform line width on the a substrate having a large area.

  • Patent number: 7659215
    Abstract: Disclosed herein is a method of depositing a nanolaminate film for next-generation non-volatile floating gate memory devices by atomic layer deposition. The method includes the steps of: introducing a substrate into an atomic layer deposition reactor; forming on the substrate a first high-dielectric-constant layer by alternately supplying an oxygen source and a metal source selected from among an aluminum source, a zirconium source and a hafnium source; forming on the first high-dielectric-constant layer a nickel oxide layer by alternately supplying a nickel source and an oxygen source; and forming on the nickel oxide layer a second high-dielectric-constant layer by alternately supplying an oxygen source and a metal source selected from among an aluminum source, a zirconium source and a hafnium source.
