Abstract
A semiconductor package comprises a lead frame, a die pad, bond pads, and leads. A die may be arranged on the die pad, the die comprising an integrated circuit. In an example, the die and at least a portion of the lead frame are encapsulated with a molding compound (MC). A first thickness of the MC over a first portion of the die is less than a second thickness over a second portion of the die to form a cavity in the MC and the MC directly contacts the first portion and the second portion of the die.
