Abstract :
This paper presents a practical heatsink fabrication process for low-cost, high-power microwave and millimeter-wave devices. Using this process approach, a heatsink is developed on a very thin epilayer structure, without damaging the active layer of the device. The etch-stop layer between the wafer and the front-side power devices acts as a protective layer during the back-side fabrication process, and reduces the contact resistance between the device and its heatsink. The paper describes the complete fabrication procedure developed to realize the Gunn devices for low-cost millimeter-wave applications
