BJTs

The ICS Instructions contain the basic procedures for making measurements and performing modeling. This screen is intended to point out things unique to using the PNP model file.

Device Selection

You should measure one of the square emitter BJTs. The third BJT from the left on the bottom row is recommended. Normally, you will be required to measure 3 such BJTs from different device cells.

Probe Assignments

  • SMU1/probe1/CM(H)---->Base
  • SMU2/probe2---->Collector
  • SMU3/probe3---->Emitter
  • SMU4/probe4 is not used.
Note: CM(L) will have to be moved between the Collector(probe2) and Emitter(probe3) as needed to complete the measurements.
