| 摘要 |
The present invention provides a silicon epitaxial wafer having an excellent IG capability all over the radial direction thereof and a process for manufacturing the same. The present invention is directed to a silicon epitaxial wafer having an excellent gettering capability all over the radial direction thereof, wherein density of oxide precipitates detectable in the interior of a silicon single crystal substrate after epitaxial growth is 1x10<9>/cm<3> or higher at any position in the radial direction. <IMAGE> |
