Abstract

The present disclosure relates to a radio frequency device that includes a mold device die and a multilayer redistribution structure underneath the mold device die. The mold device die includes a device region with a back-end-of-line (BEOL) portion and a front-end-of-line (FEOL) portion over the BEOL portion, and a first mold compound with nanotube particles. The FEOL portion includes isolation sections and an active layer surrounded by the isolation sections. The nanotube particles are dispersed throughout a bottom portion of the first mold compound, and have a higher thermal conductivity than the first mold compound alone. The bottom portion of the first mold compound resides over the active layer and top surfaces of the isolation sections. The multilayer redistribution structure includes a number of bump structures, which are at a bottom of the multilayer redistribution structure and electrically coupled to the FEOL portion of the mold device die.
