Abstract:
A power cell including an isolation region having a first dopant type formed in a substrate. The power cell further includes a bottom gate having a second dopant type different from the first dopant type formed on the isolation region and a channel layer having the first dopant type formed on the bottom gate. The power cell further includes source/drain regions having the first dopant type formed in the channel layer and a first well region having the second dopant type formed around the channel layer and the source/drain regions, and the first well region electrically connected to the bottom gate. The power cell further includes a second well region having the first dopant type formed around the channel layer and contacting the isolation region and a gate structure formed on the channel layer.
