Applications

Evaluate Multi-channel Devices

Previous

parametric testers overly
complicated the measurement of
multi-channel devices. Users had
to interconnect current/voltage

sources, nanovoltmeters, and pico­ammeters. The HP 4142B integrates
these features into one instrument,
thereby simplify the procedure
and reducing test time. A typical
configuration includes:

1 HP 41420A (2 slots)

Source Monitor Unit

4HP41421B

(4 slots)

Source Monitor Unit
1 HP 41424A VS/VMU (1 slot)
1 HP 41425A (1 slot)

Analog Feedback Unit

This assortment of modules suits

most applications. You can test ECL
circuits, multiple MOSFETs, ring
oscillators, operational amplifiers,
analog/digital switches, and hybrid
circuits. For example, stimulating
several MOSFETs at once lets you
extract AL, AW, and a host of swept
parameters (ID-IDS, ITI-VGS, G,-Vos,
and V, vs. Temperature).

Characterize High Power and

Smart Power Devices
Combine the HP 4142B and

HP 16087A switch to automate test­ing of your devices which require
both high power and sub-PA resolu­tion. The ability of the HP 4142B to

easily synchronize and combine

plug-in modules, allows expanded

coverage to 2000V and 20A. The
HP 16087A is a 3-input scanner
which greatly simplifies your task
of configuring HVUs, HCUs, or
SMUs for single insertion testing.

The HP 4142B also provides a
general purpose 16-bit TTL output

(open collector) for extended sys­tems functions, such as external
relay controls and/or controlling

test device internal settings. This

insures your ability to exercise your

smart power devices fully with a

single test setup.

GaAs Test and Development
The ability to provide DC and RF in

both continuous and pulsed modes

is important for testing gallium

arsenide (GaAs) and other micro­wave devices. To verify process
quality and device performance,
you need a versatile DC parameter
test instrument which can also act
as a bias supply during RF test. Con-

ventional power supplies and volt-

meters provide awkward solutions

which can damage high frequency

devices or produce erroneous

results if not carefully used.

The precision DC parametric

measurement capability and flexible
configuration of the HP 4142B make

it ideal for comprehensive test of
microwave devices in R&D or pro­duction. Its SMU architecture pre­vents damage due to bias supply
glitching or overshoot. Its pulse
capability reduces thermal drift

error and allows testing of high
power devices, even at the wafer
level.

Applications

The HP 4142B

obtains all DC
parameters and
provides RF
biasing for single
connection
microwave testing.

Upgrade to a Full Process Monitor System

The HP 4142B was designed for
high throughput without sacrificing
accuracy or resolution. By adding
a capacitance meter, switching

matrix, and software, you can
upgrade your HP 4142B to the
HP 4062C Process Control System.
Your HP 4142B software investment
is preserved with this migration as
well. Use the HP 9000 Series 300
controller, or IBM PC compatible
with HP co-processor card to make
DC or capacitance measurements
which meet your R&D or produc-

tion test requirements. The HP
4085B switching matrix is specially

designed for overhead probing, and

guarantees full system accuracy
right down to the wafer probing
interface.

Features

Modular Architecture
The HP 4142B provides eight slots

for a variety of plug-in measurement
units. Reduce startup costs by cus­tomizing the HP 4 142B for your
application. As your needs increase,
simply add more units. As you
move from benchtop to production,
easily migrate your tests by adding a
compatible wafer prober, switching
matrix, capacitance meter, and
system software.

Versatile Source Monitor Units

(SMUs)
For general purpose DC or pulsed

measurements, use the HP 4142B
Source Monitor Units. The equiva­lent of four instruments, these pre­cision modules force voltage while
measuring currents down to 2OfA
Or force current and simulta­neously monitor voltages down
to 4Op.V. The HP 41421B SMU con-

serves space (1 slot) by limiting

ranges to -+ 1OOV and + 1OOmA. The
HP 41420A (2 slots) extends the
range to & 200V and -+ 1A.

Both SMUs are four-quadrant
sources using full active guard and
Kelvin connections. The active
guard minimizes voltage differen­tials which add significant noise and

cable loss errors when measuring
currents below 1pA. The 4-wire Kel-

vin sensing on the SMUs and built-

in Ground Unit (GNDU) assure
accuracy right to the device pins,
eliminating resistive cable loss
errors when measuring low volt­ages or large currents.

Create high power
plots in seconds
by pulsing the
HCU and SMU
synchronously.

HP 41422A High Current Unit
Use the HP 41422AHigh Current

Unit to make fast 100~s pulsed mea­surements up to + 1OV and 1OA. It is
a pulsed source/monitor unit with
the same 5-digit basic accuracy of
the standard SMUs. A specially low-

inductance cable design and built-in
ground return let you make low
level and high power tests with
equal ease.

Synchronized pulse capability has
been added to the HCU so that it

can be used in tandem with another
HCU or the standard SMUs. Prevent
thermal drift or damage by using
this dual pulse feature to sweep

your high power devices.

HP 41423A High Voltage Unit

Features

Safely and reliably make DC or
pulsed measurements to + 1000 V
with the HVU source monitor unit.
Its low leakage design allows cur­rent measurements down to 2 PA.

A special high voltage triaxial cable,

connectors, fixture interlock, and a
LED status indicator provide hazard
protection and convenience while
maintaining full system accuracy.

The HVU has the same pulse

capability as the standard SMUs,
including the unique quasi-pulse
mode. Quasi-pulse is an advanced

pulse feature allowing a source to

monitor its slew rate and abruptly

power down when a specific voltage

or current compliance condition is
met. You can very rapidly determine

voltage breakdowns while minimiz-

ing the risk of damage due to exces­sive stress. Or speed up leakage
current measurement times by
monitoring the current automati­cally when the voltage reaches a
specified stop value.

HP 41425A Analog Feedback Unit

To find important parameters that

are specified at a given voltage or

current, such as V;, or h,, connect
the HP 41425A Analog Feedback
Unit between two SMUs. The AFU
modulates the output voltage of one
SMU while monitoring the current
or voltage of the second SMU. ‘I&+­get currents and voltages are found
with blazing speed (12 msec).
The AFU is connected internally,
so no external hookup is
necessary.

You can perform useful measure-

ments which were previously
impractical using lengthy binary

searches. For example, quickly
monitor V,, vs substrate bias or V,,
vs Temperature. Or use the AFU
with a network analyzer to quickly
search for bias conditions during

characterization of a microwave
transistor.

HP 41425A Analog Feedback Unit

The HP 41425A AFU searches for a target current or voltage on one

SMU by controlling (sweeping) the output voltage of another SMU.
It requires one slot and two SMUs. Only one AFU can be used per
HP 4142B mainframe. SMUs may be either the HP 41420A HPSMU or
HP 41421 B MPSMU. The analog search capability of the AFU reduces

the time required for measurements like h,, or V,, which would

otherwise require a more lengthy binary search technique.
