    • To enable a barrier layer including a titanium film of good quality to be efficiently formed even at a low temperature and enable a TiSix film to be self-conformably formed at the interface between the titanium film and the base. In the step of forming the TiSix film (507), the following steps are repeated two or more times without introducing argon gas into the treating chamber: a first step in which a titanium compound gas is introduced into the treating chamber to adsorb the titanium compound gas onto the silicon surface of a silicon substrate (502); a second step in which the introduction of the titanium compound gas into the treating chamber is stopped and the titanium compound gas remaining in the treating chamber is removed; and a third step in which a plasma is generated in the treating chamber while introducing hydrogen gas into the treating chamber to thereby reduce the titanium compound gas adsorbed on the silicon surface and react it with the silicon in the silicon surface to form the TiSix film (507).
    • 为了能够即使在低温也能够有效地形成包含质量好的钛膜的阻挡层,能够使TiSix膜在钛膜与基材之间的界面处自形地形成。 在形成TiSix膜(507)的步骤中,重复两次以上的步骤而不向处理室中引入氩气:第一步骤,其中将钛化合物气体引入处理室以吸附钛化合物 气体到硅衬底(502)的硅表面上; 第二步骤是停止将钛化合物气体引入处理室,并且除去残留在处理室中的钛化合物气体; 以及第三步骤,其中在处理室中产生等离子体,同时将氢气引入处理室中,从而减少吸附在硅表面上的钛化合物气体,并与硅表面中的硅反应形成TiSix膜( 507)。
