Abstract:
The present disclosure provides a superjunction based design for normally-OFF HEMT that has two key components: (i) a recessed high-K metal gate and (ii) a superjunction layer under the gate, which is embedded within the N-type GaN buffer layers and separated from recessed gate. Recess gate is to deplete the 2DEG from the channel region (under the gate) when the transistor is under OFF state. The present disclosure provides a new, improved, efficient and technically advanced HEMT device which can provide higher breakdown voltage, when compared to designs available in the prior-art, without affecting the performance figure of merits. Further, the new HEMT device offers improved breakdown voltage as compared to ON-resistance trade-off, improved the short channel effects, improved gate control over channel, improved switching speed for a given breakdown voltage, and improved device reliability. Furthermore, the new HEMT device lowers gate-to-drain (miller) capacitance and is available at low cost.

Claim (Index 15):
The transistor as claimed in  claim 14 , wherein the one or more doped GaN layers consist of any or a combination of n-doped GaN layers and p-doped GaN layers disposed between at least two intrinsically doped GaN (i-GaN) layers or disposed within an i-GaN layer.
