Getting Started
This guide introduces how to use HP 4155A Semiconductor Parameter
Analyzer and HP 4156A Precision Semiconductor Parameter Analyzer. Basic
operations of the HP 4155A/4156A are provided.
This guide consists of the following three sections:
Making a measurement
: preparing for measurements and measuring a
sample device (MOS FET).
Analyzing a result
: analyzing the results graphically and searching for the
threshold voltage (Vth) of the MOS FET.
If you have a problem
: providing solutions to problems you may
encounter while using this guide.
Before going to the next page, make sure you have prepared the following:
HP 4155A or HP 4156A
HP 16442A test xture
Test device (n-channel MOS FET, enhancement type)
In this guide, the test device used is a Siliconix SD214DE.
This guide book assumes that you have already installed
your HP 4155A/4156A. If not, refer to \Installation" in the
HP 4155A/4156A User's Task Guide.
