    • Provided is a method for manufacturing a semiconductor device, including a dual-stage deposition step including: a first stage for introducing tantalum penta-ethoxide containing tantalum as a material gas into a reaction chamber in which a semiconductor substrate on a surface of which a lower electrode is made of ruthenium is placed to thus form a tantalum oxide film by a vapor-phase growth method such as a chemical vapor deposition method and the following second stage for removing from the reaction chamber the material gas introduced into the reaction chamber at the first stage and a byproduct produced at the first stage by introducing a nitrogen gas, and wherein the tantalum oxide film is formed on the semiconductor substrate, by repeating the dual-stage deposition step two or more times.
    • 本发明提供一种半导体装置的制造方法,其特征在于,包括:第一阶段,将含有钽的钽五乙酸盐作为原料气体引入反应室,其中表面上的半导体衬底的下层 电极由钌制成,由此通过气相生长法如化学气相沉积法形成氧化钽膜,以及随后的第二阶段,用于从反应室除去在第一个反应室中引入反应室的原料气体 通过引入氮气在第一阶段产生副产物,并且其中通过重复两级沉积步骤两次或更多次在半导体衬底上形成氧化钽膜。
