  • Publication number: 20110086510
    Abstract: A semiconductor device relating to the present invention has multiple gate electrodes arranged on a semiconductor substrate at a narrow spacing and an interlayer insulating film covering the gate electrodes. The interlayer insulating film consists of a hygroscopic insulating film filling gate electrode spacing with a thinner thickness on the gate electrodes than the film thickness on the flat surface of the semiconductor substrate and low-hygroscopic insulating film formed on the hygroscopic insulating film. This structure enables suppressing an increase of contact resistance due to H2O liberated from the hygroscopic insulating film even if very fine contact is formed between the adjacent gate electrodes.

  • Publication number: 20090261478
    Abstract: The present invention constitutes a semiconductor device wherein a Ni-containing metal silicide layer is formed on a semiconductor substrate and its uppermost surface is nitrided. According to this structure, a dangling bond of silicon existing in the metal silicide layer and nitrogen are bonded by nitridation of the uppermost surface of the metal silicide layer. Therefore, diffusion of oxygen into the metal silicide layer can be suppressed. As a result, electrical insulation due to oxidation of the metal silicide layer can be reduced and the contact resistance can be stabilized.
