Patent ID: 10991817

Abstract:
Techniques are disclosed for forming group III-N transistors including a source to channel heterostructure design. As will be apparent in light of this disclosure, the source to channel heterostructure design may include inserting a relatively high bandgap material layer (e.g., relative to the bandgap of the channel material) between the source and channel of the III-N transistor. In some such embodiments, the relatively high bandgap material layer may be a portion of the polarization charge inducing layer formed over the III-N layer including the channel (e.g., to form a heterojunction/2DEG configuration) that is purposefully left in the source region when forming the source/drain trenches. The source to channel heterostructure design can be used to enhance the high frequency performance of the III-N transistor. Other embodiments may be described and/or disclosed.
