Abstract:
A semiconductor device having a silicon substrate, comprising:first silicon oxide films on said silicon substrate to electrically separate said device from another device;a pair of diffusion regions in said substrate between said first silicon oxide films and which serves as source and drain regions;a gate oxide film formed between said diffusion regions and on said silicon substrate;a gate electrode placed on said gate oxide film;silicide layers formed on said gate electrode and in surface regions of said diffusion regions;a second silicon oxide film covering said first silicon oxide film, said diffusion regions, said gate oxide film, said gate electrode and said silicide layers;a diamond-like carbon layer formed on said second silicon oxide film and forming a water impermeable barrier over said gate oxide film;a third silicon oxide film formed on said diamond-like carbon layer; anda fourth silicon oxide film formed on said third silicon oxide film,wherein said second silicon oxide film, said diamond-like carbon layer, said third silicon oxide film and said fourth silicon oxide film are sequentially laminated in this order over said silicon substrate so as to serve as interlayer insulative layers.
