Abstract: Multiple planes within the sample are exposed from a single perspective for contact by an electrical probe. The sample can be milled at a non-orthogonal angle to expose different layers as sloped surfaces. The sloped edges of multiple, parallel conductor planes provide access to the multiple levels from above. The planes can be accessed, for example, for contacting with an electrical probe for applying or sensing a voltage. The level of an exposed layer to be contacted can be identified, for example, by counting down the exposed layers from the sample surface, since the non-orthogonal mill makes all layers visible from above. Alternatively, the sample can be milled orthogonally to the surface, and then tilted and/or rotated to provide access to multiple levels of the device. The milling is preferably performed away from the region of interest, to provide electrical access to the region while minimizing damage to the region.

Abstract: In a method for determining a set value of a pressure for inspection in a wafer inspection apparatus, a surrounding space sealable between a chuck top and a probe card by a vacuum mechanism is evacuated and a highest negative pressure in the surrounding space is measured as a reference pressure when the chuck top has floated by the evacuation. Then as a reference height position, a height position of the chuck top corresponding to the reference pressure is obtained. Further, a pressure in the surrounding space is decreased to a level lower than the reference pressure, the pressure in the surrounding space, when the chuck top reaches a target height position obtained by adding a preset overdrive amount for a press-contact state between the probe card and the wafer to the reference height position, is measured and the measured pressure is set as the set value of the pressure.

Abstract: A magnetic field sensor formed by a Hall cell having a first, second, third and fourth conduction nodes electrically coupled together by resistive paths. Flowing between the first and second conduction nodes is a control current. In the presence of a magnetic field, a difference of potential due to the Hall effect is generated between the third and fourth conduction nodes. An operational amplifier has an inverting input terminal coupled to the fourth conduction node, a non-inverting input terminal biased at the voltage at the third conduction node, and an output terminal coupled in feedback mode to the inverting input by a feedback resistor. The current generated in feedback through the feedback resistor generates a voltage indicating unbalancing, due to the Hall effect, between the third and fourth conductive nodes, and consequently indicates the intensity of the magnetic field that acts upon the Hall cell.
