Patent ID: 8680854

Claim:
A semiconductor magnetometer comprising: a semiconductor structure having a bottom surface, a top surface, and a cavity that extends from the top surface down into the semiconductor structure, the cavity having a bottom surface that lies above and vertically spaced apart from the bottom surface of the semiconductor structure; a die adhesively attached to the bottom surface of the cavity, the die having a plurality of external electrical connection points; a non-conductive structure that touches the die and the top surface of the semiconductor structure; a magnetic conductor that touches the non-conductive structure, the magnetic conductor having a first end region and a second end region; a first non-magnetic conductor that touches the non-conductive structure, the first non-magnetic conductor being electrically connected to the die, and wound around the magnetic conductor in a spiral to form a coil; and a second non-magnetic conductor that touches the non-conductive structure, the second non-magnetic conductor being electrically connected to the first end region of the magnetic conductor.
