Gallium nitride power amplifier integration with metal-oxide-semiconductor devices
Certain aspects of the present disclosure provide a semiconductor device. One example semiconductor device generally includes a substrate, a semiconductor region disposed adjacent to the substrate, first fin(s) disposed adjacent to the semiconductor region, first gate region(s) disposed adjacent to the first fin(s), first drain contact(s) disposed above the first fin(s), first source contact(s) disposed below the substrate, a second fin disposed above the semiconductor region, and a second gate region, second source contact and second drain contact disposed adjacent to the second fin and above the semiconductor region. First path(s) are formed between the first drain contact(s) and the first source contact(s) for current flow(s) through the first fin(s) in a vertical direction along the first path(s). A second path is formed between the second source contact and the second drain contact for current flow through the second fin in a horizontal direction along the second path.
