Assignee: INFINEON TECHNOLOGIES AUSTRIA AG
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A gate driver device, comprising:
a first field effect transistor comprising a first gate electrode and a first backgate structure; and
a first driver circuit configured to supply a first backgate drive signal to the first backgate structure,
wherein the first backgate structure comprises a first well formed in a semiconductor substrate,
wherein a conductivity type of the first well is opposite to a conductivity type of a bulk portion of the semiconductor substrate,
wherein doped regions of the first field effect transistor are formed in a first semiconductor layer,
wherein a dielectric layer is formed between the semiconductor substrate and the first semiconductor layer, and
wherein the first driver circuit is configured to supply the first backgate drive signal to the first well.
