Abstract

See full text

A three-dimensional Gate-Wrap-Around Field-Effect Transistor (GWAFET). The GWAFET includes a substrate of III-V semiconductor material. The GWAFET further includes one or more channel layers with a gate wrapped around these one or more channel layers. Additionally, the GWAFET includes a barrier layer residing on the top channel layer with a layer of doped III-V semiconductor material residing on each end of the barrier layer. A source and drain contact are connected to the layer of doped III-V semiconductor material as well as to the multiple channels in the embodiment with the GWAFET including multiple channel layers. By having such a structure, integration density is improved. Furthermore, electrostatic control is improved due to gate coupling, which helps reduce standby power consumption. Furthermore, by using III-V semiconductor material as opposed to silicon, the current drive capacity is improved.
