Abstract
The present disclosure relates to an air-cavity package, which includes a substrate, a base, and a semiconductor die. The substrate includes a substrate body, thermal vias extending through the substrate body, and a metal trace on a bottom side of the substrate body and separate from the thermal vias. The base includes a base body, a perimeter wall extending about a perimeter of the base body, and a signal via structure. Herein, the bottom side of the substrate body resides on the perimeter wall to form a cavity, and the signal via structure extends through the perimeter wall and is electrically coupled to the metal trace. The semiconductor die is mounted on the bottom side of the substrate body, exposed to the cavity, and electrically coupled to the metal trace. The thermal vias conduct heat generated from the semiconductor die toward a top side of the substrate body.
