Patent ID: 10062713

Abstract:
An integrated circuit includes a first device having a first threshold voltage (Vt) adjusting implant extension region having a first conductivity type and extending from a first implant rail region under an entirety of a first channel region. The first implant rail region and first Vt adjusting implant extension region are contiguous, and the first channel region is over an insulating layer and the insulating layer is over the first implant rail region and first Vt adjusting implant extension region. A second device has a second Vt adjusting implant extension region having the first conductivity type and extending from a second implant rail region under an entirety of a second channel region. The second implant rail region and second Vt adjusting implant extension region are contiguous, and the second channel region is over the insulating layer and the insulating layer is over the second implant rail region and second Vt adjusting implant extension region.
