Abstract:
1. A field effect transistor, comprising: a substrate; a substrate dielectric disposed on the substrate; a bottom gate disposed on the substrate dielectric; a source disposed above the substrate dielectric and having a source extension extending from a main body of the source to be adjacent to the bottom gate; a drain disposed above the substrate dielectric and having a drain extension extending from a main body of the drain to be adjacent to the bottom gate; a channel confined by being coupled between the source extension and the drain extension, the channel making a junction contact to the bottom gate to form a JFET; a top gate disposed above the channel; a local interconnect coupled to the top gate; a first insulating spacer disposed between the top gate and the source; and a second insulating spacer disposed between the top gate and the drain.
