Abstract
In some examples, a sensor package includes a semiconductor die having a sensor; a mold compound covering a portion of the semiconductor die; and a cavity formed in a top surface of the mold compound, the sensor being in the cavity. The sensor package includes an adhesive abutting the top surface of the mold compound, and a semi-permeable film abutting the adhesive and covering the cavity. The semi-permeable film is approximately flush with at least four edges of the top surface of the mold compound.
