摘要:
A high-k dielectric film, a method of forming the high-k dielectric film, and a method of forming a related semiconductor device are provided. The high-k dielectric film includes a bottom layer of metal-silicon-oxynitride having a first nitrogen content and a first silicon content and a top layer of metal-silicon-oxynitride having a second nitrogen content and a second silicon content. The second nitrogen content is higher than the first nitrogen content and the second silicon content is higher than the first silicon content.
