Learn how you can get better correlation of results when you
perform multiple measurement types on a single system
Characterizing a semiconductor device, material, or process thoroughly requires
the ability to make three types of measurements: precision DC I-V measurements,
AC impedance measurements (often made with a C-V meter), and ultra-fast or
transient I-V measurements. Until recently, labs might have required three separate
test systems to obtain all three measurement types. In addition to added expense,
using multiple systems makes it difficult to combine different measurement types in
a single application or to correlate the results from different types of measurements
accurately. Learn more.

Tackle multiple test challenges with the
Model 4200-SCS Semiconductor Characterization System
Only the Model 4200-SCS Semiconductor Characterization System can
handle all three measurement types: precision DC I-V, AC impedance, and ultra-
fast I-V or transient I-V. Low current measurement resolution can extend to 0.1fA.
Capacitance measurements range from femtoFarads (fF) to nanoFarads (nF) at
frequencies from 1kHz to 10MHz. And ultra-fast I-V sourcing and measurement
is as easy as making DC measurements, and fast: measure both voltage and
current simultaneously for up to one million samples at 5ns per sample.

Ultra-fast I-V testing of compound semiconductor
devices and materials
Pulsed I-V testing is often performed on devices made from III-V materials, such as GaN,
GaAs, and other compound semiconductor materials. These larger band gap devices are
often used in higher power and RF devices. Pulsed I-V measurements make it possible
to manage or investigate the effects of dispersion during electrical characterization.
Sometimes it is necessary to test devices at higher frequencies in order to simulate the
conditions the actual device will encounter in regular use. Laser diodes and power
MOSFETs are two common compound semiconductor devices that often require pulse I-V
measurements for characterization. Learn more.

Learn how to determine solar cell efficiency using
the latest electrical characterization techniques
Some of the electrical tests commonly performed on solar cells involve measuring
current and capacitance as a function of an applied DC voltage. Electrical
characterization is important in determining how to make the cells as efficient as
possible with minimal losses. Capacitance measurements are sometimes made as
a function of frequency or AC voltage. Some tests require pulsed current-voltage
measurements. These measurements are usually performed at different light
intensities and under different temperature conditions. A variety of important
device parameters can be extracted from the DC and pulsed current-voltage (I-V)
and capacitance-voltage (C-V) measurements, including output current, conversion
efficiency, maximum power output, doping density, resistivity, etc. Learn more.

Plug in to greater capacitance-voltage measurement
capabilities with the Model 4210-CVU
The Model 4210-CVU, the Model 4200-SCS's optional capacitance meter,
can measure capacitance as a function of an applied DC voltage (C-V), a
function of frequency (C-f), a function of time (C-t), or a function of the
AC voltage. The Model 4210-CVU can also measure conductance and
impedance. The Keithley Test Environment Interactive (KTEI) package
combines nine new solar cell test libraries with an expanded C-V frequency
measurement range, which supports testing flat panel LCDs and organic
semiconductors such as organic light-emitting diodes (OLEDs).
