GMR-Sensor innerhalb eines geformten magnetischen Materials unter Verwendung eines nichtmagnetischen Abstandhalters |
摘要 |
<p>An integrated circuit includes a leadframe, and a die having a top surface, a bottom surface, and a plurality of perimeter sides and including at least one magnetic field sensor element disposed proximate to the top surface, wherein the bottom surface is bonded to the leadframe. A molded magnetic material encapsulates the die and at least a portion of the leadframe, and provides a magnetic field substantially perpendicular to the top surface of the die. A non-magnetic material is disposed between the die and the molded magnetic material at least along perimeter sides of the die intersecting a lateral magnetic field component which is parallel to the top surface of the die.</p> |
