Beneath the Optical Microscope (OM) and Scanning Electron Microscope (SEM), probes are connected to internal circuits of an IC, allowing connection with external devices for inputting signals or conducting electrical measurements.
The Superiority of iST
Run measurement under different packaging, e.g. BGA ball, pad, FIB pad.
Vgs vs. Ids curve:
When fixing Vds of a transistor, Ids varies when Vgs changes, forming a “Vgs vs. Ids” curve.
This curve can be used for studying how the carriers (electrons or “electric holes”) in the channel are raised to the conducting zone. Both the critical voltage at which a channel is formed and the critical voltage of a linear zone can be measured, providing important curves for the study of transistor characteristics.
