Improvi! Your Device Quality
The HP 4145B performs fast, accurate analysis of
semiconductor devices to increase your productivity
and improve your device quality. You can stimulate
and measure voltage and current sensitive devices
easily with the four Source Monitor Units (SMUs).
And to help you analyze data, the HP 4145B
computes dc parameters like h,, and gm for you.
The HP 4145B’s versatile SMU-based architecture
saves you valuable time and eliminates measurement
instabilities caused by changing DUT connnections.
Each SMU can alternately act as a voltage source/
current monitor or current source/voltage monitor.
You can characterize a four-terminal device completely without changing device connections simply change the SMU’s current/voltage
operating mode.
Increase Productivity on the Bench
or in a System
You can produce results from the start with the
HP 4145B. Use the powerful front panel keys for
control and analysis in stand-alone bench-top
applications. Or use the HP 4145B’s Auto
Sequence Programming to control measurements,
data storage, and plotting functions without using
a computer. And, since the HP 4145B is completely
programmable, you can easily incorporate it into an
automatic test system to increase your test
throughput.
Shorten Your Design and
Analysis Times
The HP 4145B automates tedious data gathering
during device characterization. When design
changes are made, you can evaluate them quickly
and efficiently, minimizing project delays and
cost overruns.
At the touch of a button, the HP 4145B can
position cursors and lines on the display, giving you
direct readout of dc parameters like Early voltage
and threshold voltage. You can position a marker
anywhere on the curve and read out coordinates
directly. Or zero in fast with “auto scale”, “zoom”
and “move window“ commands.
HP 4145B Key Performance Features
Source Monitor Unit (SMU)
The HP 4145B provides you with four SMUs. Each
SMU can be used as a voltage source/current monitor or
as a current source/voltage monitor.
SMU Range:

I: +1 pAdc to klOO.0 mAdc
(3~50 fA resolution in current monitor mode)
Accuracy:
V: +0.15% to -1-(0.15% + 40 mV)
I: 50.4% to+1.8%
Measurement Speed
Make up to 150 measurements per second.
Voltage Monitor (VM)
Two voltage monitors are built into the
HP 4145B in addition to the SMUs.
Measuring Ranges: +~O.OOO Vdc and
+2.0000 Vdc
