| 摘要 |
This invention generally relates to an epitaxial silicon semiconductor wafer with increased thermal conductivity to transfer heat away from a device layer, while also having resistance to common failure mechanisms, such as latch-up failures and radiation event failures. The semiconductor wafer comprises a lightly-doped device layer, a highly-doped protective layer, and a lightly-doped substrate. The invention is also directed to a process for forming such an epitaxial silicon wafer. |
