Abstract
【解決手段】半導体装置の製造方法は、半導体基板の表面の上方に、面心立方構造を有する助触媒層を形成することを含む。ここで、前記面心立方構造の(111)面が前記半導体基板の前記表面と平行に配向するように前記助触媒層を形成する。前記助触媒層上に、面心立方構造を有する触媒層を形成する。ここで、前記面心立方構造の(111)面が前記半導体基板の前記表面と平行に配向するように前記触媒層を形成する。前記助触媒層のうち前記触媒層と接触している部分は、前記面心立方構造を有する。前記触媒層に対して酸化処理を施し、その後、前記触媒層に対して還元処理を施すことにより、前記触媒層の露出面を平坦化する。そして、前記触媒層上にグラフェン層を形成する。
