Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. An electronic device, comprising:
a first electrical component; and
an electrical component device comprising:
a buffer layer disposed over a frontside surface of a substrate;
a first layer of gallium nitride disposed over the buffer layer;
a second layer of aluminum gallium nitride disposed over the first layer, wherein a two-dimensional electron gas (2DEG) layer is disposed at an interface between the first layer and the second layer;
a trench formed from a backside surface of the substrate through the substrate, through the buffer layer, through the first layer, and through the 2DEG layer, wherein the trench creates a gap in the 2DEG layer to produce a first 2DEG segment and a second 2DEG segment; and
a second electrical component positioned over the second layer and over at least a portion of the gap between the first and the second 2DEG segments, wherein the second electrical component is operably connected to the first electrical component.
