Disclosed is a fault isolation and measurement system that provides
multiple near-field scanning isolation techniques on a common platform.
The system incorporates the use of a specialized holder to supply
electrical bias to internal circuit structures located within an area of
a device or material. The system further uses a multi-probe assembly.
Each probe is mounted to a support structure around a common reference
point and is a component of a different measurement or fault isolation
tool. The assembly moves such that each probe can obtain measurements
from the same fixed location on the device or material. The relative
positioning of the support structure and/or the holder can be changed in
order to obtain measurements from multiple same fixed locations within
the area. Additionally, the system uses a processor for providing layered
images associated with each signal and for precisely aligning those
images with design data in order to characterize, or isolate fault
locations within the device or material.
