Claim:
1. A fingerprint sensor device comprising: a substrate having a top substrate side, a bottom substrate side, and lateral substrate sides between the top and bottom substrate sides, the substrate comprising a conductive pattern on the top substrate side; a semiconductor die having a top die side, a bottom die side, and lateral die sides between the top and bottom die sides, where the top die side comprises an uppermost planar side of the semiconductor die and the semiconductor die comprises a bond pad on the top die side; a bond wire electrically connecting the bond pad and the conductive pattern; an encapsulating material surrounding the lateral die sides and having a top encapsulant side, a bottom encapsulant side, and lateral encapsulant sides between the top and bottom encapsulant sides; a dielectric layer (DL) having a top DL side, a bottom DL side coupled to the top die side, and lateral DL sides between the top and bottom DL sides; and a plate through which a fingerprint is sensed, the plate having a top plate side, a bottom plate side coupled to the top DL side, and lateral plate sides between the top and bottom plate sides, where the plate is positioned over only a portion of the top die side that is laterally offset from the bond pad.
