Abstract:
1. A flip chip packaged component comprising: a die having a first surface; a dielectric barrier disposed on the first surface of the die, the dielectric barrier at least partially surrounding a designated location on the first surface of the die; a plurality of bumps disposed on the first surface of the die, the plurality of bumps being located on an opposite side of the dielectric barrier from the designated location; a substrate including a plurality of bonding pads on a second surface of the substrate, the die bonded to the substrate in a flip chip configuration, the plurality of bumps bonded to the plurality of bonding pads, the dielectric barrier contacting the substrate; a cavity defined by the first surface of the die, the dielectric barrier, and the substrate, the cavity being proximate the designated location on the first surface of the die; and a molding compound encapsulating the die and at least a portion of the substrate, the molding compound underfilling a portion of the die and contacting the opposite side of the dielectric barrier from the designated location, the dielectric barrier preventing the molding compound from entering the cavity.
