Semiconductor device and method for fabricating the same |
摘要 |
A method for fabricating semiconductor device is disclosed. The method includes the steps of: providing a substrate; forming a doped region in the substrate; forming a thermal oxide layer on the substrate and the doped region; removing the thermal oxide layer to form a first recess; forming an epitaxial layer on the substrate and in the first recess; and forming a gate dielectric layer in the epitaxial layer. |

1. A method for fabricating semiconductor device, comprising:
providing a substrate; forming a doped region in the substrate; forming a thermal oxide layer on the substrate and the doped region; removing the thermal oxide layer to form a first recess; forming an epitaxial layer on the substrate and in the first recess after removing the thermal oxide layer; and forming a gate dielectric layer in the epitaxial layer. |
