Abstract:
A field effect transistor (FET) having one or more fins provides an extended current path as compared to conventional finFETs. A raised source terminal is disposed on a fin adjacent to a sidewall spacer of a gate structure. The drain terminal and a first portion of the gate structure overlie a first well of a first conductivity type. A raised drain terminal is disposed such that it is spaced apart from the gate structure sidewalls. In some embodiments the drain terminal is disposed on a second, separate fin. the drain terminal and a second portion of the gate structure overlie a second well of a second conductivity type.
