made.
How to control a probe station
This tutorial demonstrates how to control a probe station to test five identical sites (or die or
reticles) on a sample wafer.
Each wafer site has two subsites (or test element groups). At each subsite there are two devices
(or test elements) to be tested:
• 4-terminal N-channel MOSFET
• 3-terminal NPN transistor.
The subsites need not be identical, but for simplicity they are assumed to be the same. This is
illustrated below in Figure 4-21.
