Patent ID: 7816772

Claim:
An integrated circuit device, comprising: at least one die attached to a leadframe having lead fingers; wirebonds making connections between the at least one die and the leadfingers; a first mold material injected at a first pressure to prevent wire sway of the wirebonds for encapsulating the wirebonds and covering at least a portion of the at least one die and the leadfingers, wherein the first mold material is only on a die-side of the leadframe and overmolds all wirebonds connected to the at least one die; a concentrator having a first side and a second side, wherein the first side is secured to a non die-side of the leadframe; a magnet secured to the second side of the concentrator, and a second mold material injected at a second pressure greater than the first pressure for overmolding the at least one die, first mold material, concentrator, and magnet.
