    Abstract: A structure and method for a semiconductor device includes a silicon device layer and a gallium nitride (GaN) device layer. In an embodiment, the silicon device layer and the GaN device layer have upper surfaces which are coplanar with each other. In another embodiment, the GaN device layer does not directly underlie the silicon device layer, and the silicon device layer does not directly underlie the GaN device layer. The semiconductor device can further include a silicon-based semiconductor device formed on and/or within the silicon device layer, and a nitride-based semiconductor device formed on and/or within the GaN device layer. The GaN device layer can include a plurality of layers which can be formed as conformal blanket layers and then planarized, or which can be selectively formed then planarized.

    Abstract: Exemplary embodiments provide structures and methods for power devices with integrated clamp structures. The integration of clamp structures can protect the power device, e.g., from electrical overstress (EOS). In one embodiment, active devices can be formed over a substrate, while a clamp structure can be integrated outside the active regions of the power device, for example, under the active regions and/or inside the substrate. Integrating clamp structure outside active regions of power devices can maximize the active area for a given die size and improve robustness of the clamped device since the current will spread in the substrate by this integration.
