Abstract
A field effect transistor may include an active layer containing an oxide compound material of at least two atomic elements including a first element of tin and a second element selected from Ge, Si, P, S, F, Ti, Cs, and Na and located over a substrate. The field effect transistor may further include a gate dielectric located on the active layer, a gate electrode located on the gate dielectric, and a source contact structure and a drain contact structure contacting a respective portion of the active layer. The oxide compound material may include at least germanium and tin. The oxide compound semiconductor material may be used as a p-type semiconductor material in BEOL structures.
