The present disclosure relates to a radio frequency device and a process for making the same. According to the process, a precursor wafer, which includes device regions, individual interfacial layers formed of SiGe, and a silicon handle substrate, is first provided. Each individual interfacial layer is over an active layer of a corresponding device region, and the silicon handle substrate is over each individual interfacial layer. A first bonding layer is formed underneath the precursor wafer. The precursor wafer is then attached to a support carrier with a second bonding layer. The first bonding layer and the second bonding layer merge to form a bonding structure between the precursor wafer and the support carrier. Next, the silicon handle substrate is removed from the precursor wafer to provide an etched wafer, and a first mold compound is applied to the etched wafer to provide a mold device wafer.
