Abstract
A method of fabricating a normally 'off' GaN heterostructure field effect transistor having a source and a drain including depositing a passivation layer patterned to cover a channel region between a source and a drain, forming a first opening in the passivation layer, the first opening for defining a gate area in the channel region and the first opening having a first length dimension along a direction of current flow between the source and the drain, and implanting ions in an implant area within the gate area, wherein the implant area has a second length dimension along the direction of current flow shorter than the first length dimension.
