    Abstract: In a general aspect, a semiconductor device assembly includes a first portion of a semiconductor substrate; a second portion of the semiconductor substrate, and a semiconductor device layer disposed on the first portion of the semiconductor substrate and the second portion of the semiconductor substrate. The semiconductor device layer includes a first semiconductor device disposed on the first portion of the semiconductor substrate, and a second semiconductor device disposed on the second portion of the semiconductor substrate. The assembly also includes an isolation trench defined in the semiconductor substrate that has a dielectric material disposed therein. The isolation trench is disposed between the first portion of the semiconductor substrate and the second portion of the semiconductor substrate, and electrically isolates the first portion of the semiconductor substrate from the second portion of the semiconductor substrate. The semiconductor device layer excludes the isolation trench.

    Abstract: An electronic device can include a drain electrode of a high electron mobility transistor overlying a channel layer; a source electrode overlying the channel layer, wherein a lowermost portion of the source electrode overlies at least a portion of the channel layer; and a gate electrode of the high electron mobility transistor overlying the channel layer; and a current limiting control structure that controls current passing between the drain and source electrodes. The current limiting control structure can be disposed between the source and gate electrodes, the current limiting control structure can be coupled to the source electrode and the first high electron mobility transistor, and the current limiting control structure has a threshold voltage. The current limiting control structure can be a Schottky-gated HEMT or a MISHEMT.

    Abstract: An electronic device can include an electronic component and a termination region adjacent to the electronic component region. In an embodiment, the termination region can include an insulating region that extends a depth into a semiconductor layer, wherein the depth is less than 50% of the thickness of the semiconductor layer. In another embodiment, the termination region can include a first insulating region that extends a first depth into the semiconductor layer, and a second insulating region that extends a second depth into the semiconductor layer, wherein the second depth is less than the first depth. In another aspect, a process of forming an electronic device can include patterning a semiconductor layer to define a trench within termination region while another trench is being formed for an electronic component within an electronic component region.
