Safety precaut ions
The following safety precautio ns should be observed before using this product and any associated ins tr um enta tion . Altho ugh
some instruments and accessories would normally be used with nonhazardous voltages, there are situations where hazardous
conditions may be present.
This product is intended for use by personnel who recognize shock hazards and are familiar with the safety precautions required
to avoid possible injury. Read and follow all installation, operation, and maintenance inform at ion careful ly before using the
product. Refer to the user documentation for complete product specifications.
If the product is used in a manner not specified, the protection provided by the product warranty may be impaired.
The types of product users are:
Responsible body is the individual or group responsible for the use and maintenance of equipment, for ensuring that the
equipment is operated within its specifications and operating limits, and for ensuring that operators are adequately trained.
Operators use the product for its intended function. They must be trained in electrical safety procedures and proper use of the
instrument. They must be protected from electric shock and contact with hazardous live circuits.
Maintenance personnel perform routine procedures on the product to keep it operating properly, for example, setting the line
voltage or replacing consumable materials. Maintenance procedures are described in the user documentation. The procedures
explicitly state if the operator may perform them. Otherwise, they should be performed only by service personnel.
Service personnel are trained to work on live circuits, perform safe installations, and repair products. Only properly trained
service personnel may perform installation and service procedures.
Keithley products are designed for use with electrical signals that are measurement, control, and data I/O connections, with low
transient overvoltages, and must not be directly connected to mains voltage or to voltage sources with high transient
overvoltages. Measurement Category II (as referenced in IEC 60664) connections require protection for high transient
overvoltages often associated with local AC mains connections. Certain Keithley measuring instruments may be connected to
mains. These instruments will be marked as category II or higher.
Unless explicitly allowed in the specifications, operating manual, and instrument labels, do not connect any instrument to mains.
Exercise extreme caution when a shock hazard is present. Lethal voltage may be present on cable connector jacks or test
fixtures. The American National Standards Institute (ANSI) states that a shock hazard exists when voltage levels greater than
30 V RMS, 42.4 V peak, or 60 VDC are present. A good safety practice is to expect that hazardous voltage is present in any
unknown circuit before measuring.
Operators of this product must be protected from electric shock at all times. The responsible body must ensure that operators
are prevented access and/or insulated from every connection point. In some cases, connections must be exposed to potential
human contact. Product operators in these circumstances must be trained to protect themselves from the risk of electric shock. If
the circuit is capable of operating at or above 1000 V, no conductive part of the circuit may be exposed.
Do not connect switching cards directly to unlimited power circuits. They are intended to be used with impedance-limited
sources. NEVER connect switching cards directly to AC mains. When connecting sources to switching cards, install protective
devices to limit fault current and voltage to the card.
Before operating an instrument, ensure that the line cord is connected to a properly-grounded power receptacle. Inspect the
connecting cables, test leads, and jumpers for possible wear, cracks, or breaks before each use.
When installing equipment where access to the main power cord is restricted, such as rack mounting, a separate main input
power disconnect device must be provided in close proximity to the equipment and within easy reach of the operator.
For maximum safety, do not touch the product, test cables, or any other instruments while power is applied to the circuit under
test. ALWAYS remove power from the entire test system and discharge any capacitors before connecting or disconnecting
cables or jumpers, installing or removing switching cards, or making internal changes, such as installing or removing jumpers.
Do not touch any object that could provide a current path to the common side of the circuit under test or power line (earth)
ground. Always make measurements with dry hands while standing on a dry, insulated surface capable of withstanding the
voltage being measured.
For safety, instruments and accessories must be used in accordance with the operating instructions. If the instruments or
accessories are used in a manner not specified in the operating instructions, the protection provided by the equipment may be
impaired.
Do not exceed the maximum signal levels of the instruments and accessories. Maximum signal levels are defined in the
specifications and operating information and shown on the instrument panels, test fixture panels, and switching cards.
When fuses are used in a product, replace with the same type and rating for continued protection against fire hazard.
Chassis connections must only be used as shield connections for measuring circuits, NOT as protective earth (safety ground)
connections.
If you are using a test fixture, keep the lid closed while power is applied to the device under test. Safe operation requires the use
of a lid interlock.
If a screw is present, connect it to protective earth (safety ground) using the wire recommended in the user documentation.
The symbol on an instrument means caution, risk of hazard. The user must refer to the operating instr u ctio ns loc ated in the
user documentation in all cases where the symbol is mark ed on the instr u ment .
The symbol on an instrument means warning, risk of electric shock. Use standard safety precautions to avoid personal
contact with these voltages.
The symbol on an instrument shows that the surface may be hot. Avoid personal contact to prevent burns.
The symbol indicates a connection terminal to the equipment frame.
If this symbol is on a product, it indicates that mercury is present in the display lamp. Please note that the lamp must be
properly disposed of according to federal, state, and local laws.
The WARNING heading in the user documentation explains hazards that might result in personal injury or death. Always read
the associated information very carefully before performing the indicated procedure.
The CAUTION heading in the user documentation explains h azard s that coul d dama ge the instrument. Such damage may
invalidate the warranty.
The CAUTION heading with the symbol in the user documentation explains hazards that could result in moderate or minor
injury or damage the instrument. Always read the associated information very carefully before performing the indicated
procedure. Damage to the instrument may invalidate the warranty.
Instrumentation and accessories shall not be connected to humans.
Before performing any maintenance, disconnect the line cord and all test cables.
To maintain protection from electric shock and fire, replacement components in mains circuits — including the power
transformer, test leads, and input jacks — must be purchased from Keithley. Standard fuses with applicable national safety
approvals may be used if the rating and type are the same. The detachable mains power cord provided with the instrument may
only be replaced with a similarly rated power cord. Other components that are not safety-related may be purchased from other
suppliers as long as they are equivalent to the original component (note that selected parts should be purchased only through
Keithley to maintain accuracy and functionality of the product). If you are unsure about the applicability of a replacement
component, call a Keithley office for information.
Unless otherwise noted in product-specific literature, Keithley instruments are designed to operate indoors only, in the following
environment: Altitude at or below 2,000 m (6,562 ft); temperature 0 °C to 50 °C (32 °F to 122 °F); and pollution degree 1 or 2.
To clean an instrument, use a cloth dampened with deionized water or mild, water-based cleaner. Clean the exterior of the
instrument only. Do not apply cleaner directly to the instrument or allow liquids to enter or spill on the instrument. Products that
consist of a circuit board with no case or chassis (e.g., a data acquisition board for installation into a computer) should never
require cleaning if handled according to instructions. If the board becomes contaminated and operation is affected, the board
should be returned to the factory for proper cleaning/servicing.

4200A-SCS system o verview
The 4200A-SCS is an automated system that provides I-V, pulsed I-V, and C-V characterization of
semiconductor devices and test structures. Its advanced digital sweep parameter analyzer combines
speed and accuracy for deep sub-micron characterization.
Tests are easily and quickly configured and executed from Clarius. Clarius is an application designed
and developed specifically for characterizing semiconductor devices and materials. Source and
measurement functions for a test are provided by up to eight source-measure units (SMUs). Test
capabilities are extended by support of a variety of external components.
Pulse source and measure tests can be provided by the 4225-PMU Ultra-fast IV pulse-measure card.
Tests requiring pulse source, but no corresponding pulse measurement, can use the 4220-PGU
pulse-only card. One typical configuration with pulse source-measure capability would be a 4200ASCS system that consists of four SMUs, two 4225-PMUs and four 4225-RPMs. This system would
then have four SMUs and four Pulse IV channels (pulse source and measure), with the RPMs
allowing for switching between pulse and SMU test resources. The primary 4200A-SCS components
and typical supported external components are illustrated in the following figure.

Source-measure unit (SMU)
The fundamental instrument module used by the 4200A-SCS is the source-measure unit (SMU). The
basic function of a SMU is to perform one of the following source-measure operations:
• Source voltage and measure current or voltage
• Source current and measure voltage or current
The source of the SMU can be configured to sweep or step voltages or currents, or to output a
constant bias voltage or current.
There are medium-power and high-power source-measure units available. The 2 W medium-power
SMUs are models 4200-SMU and 4201-SMU. The 20 W high-power SMUs are models 4210-SMU
and 4211-SMU. The following table lists the maximum limits of the SMUs.
Source-measure units
Model Maximum voltage Maximum current Maximum power
Preamplifier
A 4200-PA preamplifier adds five low-current source-measure ranges to a SMU. Without a
preamplifier, the 100 nA range (100 fA resolution) is the lowest current source-measure range for a
SMU. With a preampli fier in s talled, t he 10 n A, 1 nA, 100 pA, 10 pA, and 1 pA source-measure ranges
are added.
If preamplifiers are ordered, the 4200A-SCS is shipped from the factory with the preamplifiers
installed on the rear panel of the mainframe. The preamplifiers can be removed from the rear panel
and mounted remotely to reduce the effects of long cables on measurement quality (long cables can
add noise to low current measurements and can cause oscillation with some devices).
An installed preamplifier is matched to the SMU to which it is connected. Therefore, if you disconnect
the preamplifiers to mount them at a remote location, you must ensure that you reconnect each one
to its matching SMU.
Ground unit (GNDU)
The ground unit on the rear panel of the 4200A-SCS provides a convenient method of making ground
connections. This eliminates the need to use a SMU for this purpose.

Capacitance-Voltage Unit (CVU)
The 4210-CVU and 4215-CVU Multi-Frequency Capacitance-V olt age Uni ts are impeda nc e
measurement modules that can be installed in the 420 0A-SCS.
Capacitance-voltage (C-V) measurements are often used to characterize the gate oxide thickness,
oxide defect density, and doping profile of MOSFETs. In these measurements, as the gate voltage
varies, the capacitance of the gate to the drain and source changes. Capacitance measurements are
typically made using an ac technique. The CVUs measure ac impedance by applying a dc bias
voltage and sourcing an ac voltage across the device under test (DUT) and then measuring the
resultant ac current and phase angle.
The 4210-CVU operates from 1 kHz to 10 MHz. The ac test signal (10 mV
dc voltage biased from −30 V to +30 V.
The 4215-CVU operates from 1 kHz to 10 MHz at 1 kHz resolution. The ac test signal (10 mV to
1 V
) can be dc voltage biased from −30 V to +30 V.

Pulse source-measure hardware
The 4220-PGU High Voltage Pulse Generator Unit and 4225-PMU Ultra-Fast Pulse Measure Unit are
high-speed pulse-generator cards for the 4200A-SCS. The 4220-PGU provides pulse output only.
The 4225-PMU provides both pulse output and pulse measurement. The PGU and PMU have similar
pulse output characteristics.
The 4225-PMU can be paired one or two 4225-RPM Remote Preamplifier/Switch Modules. When the
RPM is used as a preamplifier for the PMU, it provides additional low-current measurement ranges.
When the RPM is used as a switch, it switches between the PMU, SMUs, and CVUs.

Locating the system
Locate the 4200A-SCS so that it operates within the following ambient temperature and
humidity limits:
• Temperature: +10 °C to +40 °C
• Relative humidity: 5% to 80%, noncondensing
SMU and preamplifier accuracy specifications are based on operation at 23 °C ±5 °C and between
5% and 60% relative humidity. See the 4200A-SCS datasheet at the tek.com/keithley
factors outside these ranges.
To avoid overheating, operate the instrument only in an area with proper ventilation. Allow at
least eight inches of clearance at the back of the mainframe to assure sufficient airflow and
comply with the following guidelines .
f
or derating
Guidelines to prevent overheating:
• Operate the instrument in a clean, dust-free environment.
• Keep the fan vents and cooling vents from becoming blocked (sides and rear of the instrument).
• Do not position any devices adjacent to the instrument that force air (heated or unheated) into
cooling vents. This additional airflow could compromise accuracy performance.
• When rack mounting the instrument, ensure adequate airflow around the sides, bottom, and back.
• Do not rack mount high-power dissipation equipment adjacent to the 4200A-SCS.
• To ensure proper cooling in rack environments with only convection cooling, place the hottest
equipment (for example, power supply) at the top of the rack. Place precision equipment, such as
the 4200A-SCS, as low as possible in the rack, where temperatures are the coolest. Adding
spacer panels below the instrument helps to ensure adequate airflow.

Basic system connections
This section provides basic system connections to get your 4200A-SCS set up and running.
Connecting to protective earth
The 4200A-SCS must be connected to protective earth (safety ground) using the supplied
green-yellow ground cable. Failure to attach the ground wires to a known protective earth
may result in electric shock.
Connect one lugged end of the supplied grounding cable to the protective earth (safety ground) screw
on the rear of your 4200A-SCS. See the following figure.

Connecting GPIB instruments
You can use the 4200A-SCS to control one or more external instruments using the IEEE-488 gener al
purpose instrument bus (GPIB). An example of typical instruments used in a test system with the
4200A-SCS are a switching system and an external C-V meter.
To avoid electrical interference, use only shielded IEEE-488 connecting cables. The following figure
shows how to connect GPIB instruments to the 4200A-SCS.

Connecting the interlock
The following figure shows the location of the interlock connector on the rear panel of the
4200A-SCS.
To connect the interlock:
1. Connect one end of the supplied 236-326A interlock cable to the interlock connector on the rear
panel of the 4200A-SCS (see the following figure).
Figure 8: Interlock connector on the rear panel of the 4200A-SCS
2. Connect the other end of the interlock cable to a compatible test fixture.
Configuring safety interlock operation
The following figure shows typical interlock connector wiring. A normally open switch should be used
so that an open interlock condition occurs when the switch is open.
Many test fixtures have a safety interlock connected to the instrument lid. When the lid is closed, the
interlock circuit is closed (asserted), and SMU ±200 V ranges are enabled. Conversely, the interlock
circuit is open (deasserted) when the lid is open, and SMU ±200 V ranges are disabled.

Figure 9: Interlock connector wiring
Turning the 4200A-SCS output off does not place the instrument in a safe state (an interlock
is provided for this function). Hazardous voltages may be present on all output and guard
terminals. To prevent electrical shock that could cause injury or death, never make or break
connections to the 4200A-SCS while the instrument is powered on. Turn off the equipment
from the front panel or disconnect the main power cord from the rear of the 4200A-SCS
before handling cables. Putting the equipment into an output-off state does not guarantee
that the outputs are powered off if a hardware o r software fault occurs. Precautions must be
taken to prevent a shock hazard by surroun ding the test device and any unprotected leads
(wiring) with double insulation rated for 250 V, Category O.
Prober connections
Refer to Model 4200A-SCS Prober and External Instrument Control for details on how to enable and
configure prober control for supported probers.

GPIB connections
The built-in IEEE-488 connector allows you to interface the 4200A-SCS to a variety of GPIB-equipped
devices, such as a CV meter or switching system. The unit can also be configured as a GPIB
subordinate and be controlled by an external host computer.
Configuring IEEE-488 controller operation
You can configure the 4200A-SCS to operate either as a GPIB controller or GPIB subordinate. The
4200A-SCS acts as a GPIB controller when Clarius is running. When operating as a controller, the
4200A-SCS reserves primary address 0, making that address unavailable to GPIB subordinate
devices such as GPIB switch matrices, CV meters, and probe stations. Drivers for these and other
instruments, typically integrated into semiconductor test systems, are included with the 4200A-SCS.
These drivers, called user libraries, permit Clarius and the 4200A-SCS to control GPIB subordinate
devices directly.
For instrumentation and equipment that is not supported by the standard user libraries, the open
architecture of the 4200A-SCS allows you to create your own user libraries using the Keithley User
Library Tool (KULT). Refer to Model 4200A-SCS KULT and KULT Extension Programming
(4200A-KULT-907-01) for more information regarding the standard user libraries, KULT, and
controlling external instrumentation.
Configuring IEEE-488 subordinate operation
The 4200A-SCS acts as a GPIB subordinate when the Keithley External Control Interface (KXCI)
software is running. When KXCI is running, the 4200A-SCS can be controlled by an external
computer using a command set nearly identical to the GPIB command set used to control a
Keysight 4145B Semiconductor Parameter Analyzer. For detailed information regarding KXCI, refer to
Model 4200A-SCS KXCI Remote Control Programming.
Preamplifier moun t ing
Exposure to electrical shock could result in personal injury or death. Precautions must be
taken to prevent a shock hazard by surroun ding the test device and any unprotected leads
(wiring) with double insulation that is ra ted for 250 V, Category O. See IEC 61010-1 safety
standards for details. When connecting to the 4200A-SCS SMU outputs, make sure to use
devices and cables that have ratings for th e sourc ed vo ltages. Cables with incorrect ratings
will not properly insulate the external connections to the instrument and may pose a shock
hazard. SMU and preamplifier terminals sho uld be considered hazardous even if the outputs
are programmed to be low voltage.
