    • Disclosed is a method for manufacturing a semiconductor device comprising a semiconductor substrate provided with an active element, an antioxidation film so formed on the semiconductor substrate as to cover the active element, a ferroelectric capacitor formed on the antioxidation film and having a structure wherein a lower electrode, a ferroelectric film and an upper electrode are sequentially arranged in layers, and an interlayer insulating film so formed on the antioxidation film as to cover the ferroelectric capacitor. This method for manufacturing a semiconductor device comprises a step for forming first and second contact holes in the interlayer insulating film for respectively exposing the upper electrode and the lower electrode, a step for forming an opening in the interlayer insulating film for exposing the antioxidation film, and a step for heat-treating the interlayer insulating film in an oxidizing atmosphere after forming the first and second contact holes and the opening.
    • 公开了一种制造半导体器件的方法,该半导体器件包括设置有活性元件的半导体衬底,形成在半导体衬底上以覆盖有源元件的抗氧化膜,形成在抗氧化膜上的强电介质电容器,具有下部结构 电极,铁电体膜和上电极依次排列,并且在抗氧化膜上形成覆盖铁电电容器的层间绝缘膜。 该半导体装置的制造方法包括在层间绝缘膜中形成分别暴露上部电极和下部电极的第一和第二接触孔的工序,在层间绝缘膜上形成露出抗氧化膜的开口的工序, 以及在形成第一和第二接触孔和开口之后在氧化气氛中对层间绝缘膜进行热处理的步骤。
