Abstract:
1. A semiconductor package comprising: a carrier; a semiconductor sensor comprising a bottom side and a side wall adjoining the bottom side, the semiconductor sensor coupled to the carrier such that the bottom side faces the carrier; wire-bonds electrically connecting the carrier with the semiconductor sensor; a protective layer made of an inorganic material covering at least a portion of the semiconductor sensor and directly contacting the wire-bonds; and voids between a first portion of the protective layer that directly contacts the wire-bonds and the carrier, wherein a second portion of the protective layer is in direct contact with the side wall of the semiconductor sensor where the protective layer has a thickness in the range of 5 nm to 400 nm, and wherein the voids extend between the first portion of the protective layer that directly contacts the wire-bonds and the second portion of the protective layer that directly contacts the side wall of the semiconductor sensor.
