Description

上述した課題を解決するために、本発明の1つの側面は、互いに材料が異なるターゲットが取り付けられた2つのターゲットホルダーが配された真空容器内において、前記真空容器内に不活性ガス及び反応性ガス導入された状態において前記2つのターゲットを同時にスパッタリングすることで基板に前記2つのターゲットの材料の混合物を含有する膜を成膜する際に、前記2つのターゲットの各々への前記反応性ガスの供給量が異なることを特徴とする。
また、本発明の他の側面は、真空容器内に不活性ガス及び反応性ガスを導入し、アルミニウムターゲット及びチタンターゲットを同時にスパッタリングすることで基板にアルミニウムおよびチタンの混合物を含有する膜を成膜する際に、前記チタンターゲットへの前記反応性ガスの供給量が前記アルミニウムターゲットへの前記反応性ガスの供給量よりも多いことを特徴とする。
In order to solve the above-described problems, one aspect of the present invention is that, in a vacuum vessel in which two target holders to which targets of different materials are attached are arranged , an inert gas and a reactive property are contained in the vacuum vessel . When a film containing a mixture of materials of the two targets is formed on a substrate by simultaneously sputtering the two targets in a state where a gas is introduced, the reaction to each of the two targets It is characterized in that the supply amount of the characteristic gas is different.
In another aspect of the present invention, an inert gas and a reactive gas are introduced into a vacuum vessel, and a film containing a mixture of aluminum and titanium is formed on a substrate by simultaneously sputtering an aluminum target and a titanium target. In this case, the supply amount of the reactive gas to the titanium target is larger than the supply amount of the reactive gas to the aluminum target.
