摘要： The present invention provides a magnetic field measuring method and system for determining the magnetic field of an integrated circuit (IC) inside the IC package, including the pre-packaged IC. In one embodiment, induced voltages due only to the magnetic field are determined at measurement heights on the order of the line spacings in an integrated circuit. A magnetic probe is used; the probe has a loop of wire parallel to the current, for measuring the induced voltage of the horizontal component of the magnetic field. The induced voltage due to the electric field is removed by using a calculation including the difference of two measurements. The magnetic field distribution for the integrated circuit may be determined by using the above procedure on a grid like pattern above the IC.

摘要： A magnetic field probe apparatus includes a loop-like conductor and feeder lines spaced at a distance from the loop-like conductor. The shape of the loop-like conductor and the arrangement of the feeder lines are adjusted in such a manner that the resonance frequency determined by the combination of the inductance of the loop-like conductor line and the capacitance formed between the looped-conductor and the feeder lines, is matched to the frequency of the magnetic field generated by and in the vicinity of a measurement object (e.g. electronic device) or the frequency of the electric signal which generates the magnetic field. With the magnetic field probe apparatus according to this invention, the magnetic field in the vicinity of the measurement object can be measured with high sensitivity.
