Semiconductor device and method for manufacturing the same |
摘要 |
The present invention provides a high-quality semiconductor device in which deterioration in transistor characteristics and an increase in interface layer due to a gate insulating film are suppressed, and a method for manufacturing the same. In the present invention, an interface layer, a diffusion suppressing layer and a high dielectric constant insulating film are formed sequentially in this order on one surface of a silicon substrate.
