Claim 17:
18. A method for manufacturing a semiconductor device, comprising:
forming a buffer over a substrate;
forming a shield layer over a buffer to form an interface with the buffer structure, wherein the shield layer comprises an isolation compound which is made of at least one two-dimensional material which comprising at least one metal element;
forming a first nitride-based semiconductor layer disposed over the shield layer and having a bandgap less than a bandgap of the isolation compound;
forming a second nitride-based semiconductor layer on the first nitride-based semiconductor layer, wherein the second nitride-based semiconductor layer has a bandgap less than the bandgap of the isolation compound and greater than the bandgap of the first nitride-based semiconductor layer;
forming a pair of source/drain (S/D) electrodes over the second nitride-based semiconductor layer; and
forming a gate electrode over the second nitride-based semiconductor layer and between the S/D electrodes.
