Unmatched Throughput and Flexibility for High Performance I-V Test Systems

TSP technology provides remarkable capabilities when a Series 2600A is integrated as part of a multi-channel I-V test system.

When you need to acquire data on a packaged part quickly, the wizard-based user interface of ACS Basic Edition makes it easy to find and run the test you want, like this common FET curve trace test.

For example, the embedded scripting capability allows test scripts to be run by the instrument. Test scripts are complete test programs based on an easy to use but highly efficient and compact scripting language called Lua <www.lua.org>. Since test scripts can contain any sequence of routines that are executable by conventional programming languages (including decision making algorithms), this feature allows entire tests to be managed by the instrument without sending readings back to a PC for decision making. This eliminates the delays caused by GPIB traffic congestion and greatly improves overall test times.

Also, TSP technology offers “mainframe-less channel expansion.” The TSP-Link channel expansion bus (which uses a 100 Base T Ethernet cable) allows multiple Series 2600A and other TSP instruments to be connected in a master-slave configuration and behave as one integrated system. TSP-Link supports up to 32 units or 64 SMU channels per GPIB or IP address, making it easy to scale a system to fit the particular requirements of an application.

Parallel Test Capability

The Series 2600A takes system level performance to a new height with parallel testing capability. This feature tests multiple devices in parallel to meet the high throughput requirements of production test and advanced semiconductor lab applications.

This parallel testing capability enables each instrument in the system to run its own complete test sequence, creating a fully multi-threaded test environment. Hence, the number of tests that can be running in parallel on a Series 2600A system can be as many as the number of instruments in the system. In contrast, most conventional test systems run a single thread test, usually on the controller

PC instead of the instrument itself. Testing multiple devices at the same time means dramatically improved test throughput and reduced overall cost of test.

When all or some of your test requirements change, your Series 2600A system can be reconfigured via software without rewiring. The internal software can match the different pin layouts of the devices-under-test to the appropriate SMUper-pin configurations.

Tight Timing and Synchronization

Today’s test engineers are challenged with testing increasingly more complex and more sensitive devices that require precise timing and synchronization. Whether you need to synchronize electrical and optical tests for an

optoelectronic component or ensure that the same stress times are applied to the different pins of an advanced semiconductor device, providing precision timing and synchronization between SMU channels (and external instruments) has become a critical requirement.

A high performance trigger model that is hardware driven allows timing at each source-measure step to be tightly controlled. It also synchronizes the operations between SMU channels and/or external instrumentation at hardware speeds of <500ns.

Third-generation SMU Design Ensures Faster Test Times

Based on the proven architecture of earlier Series 2600 instruments, the Series 2600A’s new SMU design enhances test speed in several ways. For example, while earlier designs used a parallel current ranging topology, the Series 2600A uses a patented series ranging topology, which provides faster and smoother range changes and outputs that settle more quickly.

The Series 2600A SMU design supports two modes of operation for use with a variety of loads. In normal mode, the SMU provides high bandwidth performance for maximum throughput. In high capacitance (high-C) mode, the SMU uses a slower bandwidth to provide robust performance with higher capacitive loads.

Each Series 2600A SMU channel offers a highly flexible, four-quadrant source coupled with precision voltage and current meters. Each channel can be configured as a:

• Precision power supply

• True current source

• DMM (DCV, DCI, ohms, and power with 5½-digit resolution)

• Electronic load (with sink mode capability)

• V or I pulse generator (Pulse width: 100µs and longer)

Current arbitrary waveforms maximum output update rates: 12,500 samples/ second.

Voltage arbitrary waveforms maximum output update rates: 20,000 samples/ second.

• V or I waveform generator

All analog-to-digital (A/D) converters in Series 2600A instruments are both high speed and high precision for maximum flexibility. The two A/D converters per channel (one for I, one for V) can run simultaneously, providing precise source-readback without sacrificing test throughput. These A/D converters offer the versatility of programmable integration rates, allowing you to optimize for either high speed (>20,000 rdgs/s at 0.001 NPLC setting) or for high resolution (up to 24 bits at 10 NPLC setting) measurements.

Digital I/O Interface

A back panel port on every Series 2600A instrument provides 14 bits of universal digital I/O to link the instrument to a variety of popular component handlers and/or probe stations. These digital I/O lines are compatible with the triggering technology of Keithley’s earlier Trigger-Link instruments. These lines simplify integrating Series 2600A instruments into systems that employ other electrical, mechanical, optical, or RF equipment.

TSP-Link Trigger Lines

The TSP-Link bus supports dedicated trigger lines that provide synchronous operations between multiple Series 2600A instruments (and other TSP instruments, such as Series 3700 DMM/Switch Systems) without the need for additional trigger connections.

Built-in Contact Check Function

The Contact Check function makes it simple to verify good device-under-test connections quickly and easily before an automated test sequence begins. This eliminates the measurement errors and false product failures associated with contact fatigue, breakage, contamination, loose or broken connections, relay failures, etc.

SUPPLEMENTAL INFORMATION

FRONT PANEL INTERFACE: Two-line vacuum fluorescent display (VFD) with keypad and rotary knob.

Display:

• Show error messages and user defined messages

• Display source and limit settings

• Show current and voltage measurements

• View measurements stored in dedicated reading buffers

Keypad Operations:

• Change host interface settings

• Save and restore instrument setups

• Load and run factor y and user defined test scripts (i.e. sequences) that prompt for input

and send results to the display

• Store measurements into dedicated reading buffers

PROGRAMMING: Embedded Test Script Processor (TSP) accessible from any host interface. Responds

to individual instrument control commands. Responds to high speed test scripts comprised of instrument control commands and Test Script Language (TSL) statements (e.g. branching, looping, math, etc.). Able to execute high speed test scripts stored in memory without host intervention.

Mini mum Memory Available: 16MB (approximately 250,000 lines of TSL code). Test Script Builder: Integrated development environment for building, running, and managing

TSP scripts. Includes an instrument console for communicating with any TSP enabled instrument in an interactive manner. Requires:

• VISA (NI-VISA included on CD)

• Microsoft .NET Framework (included on CD)

• Keithley I/O Layer (included on CD)

• Pentium III 800MHz or faster personal computer

• Microsoft Windows 98, NT, 2000, or XP

Software Interface: TSP Express (embedded), Direct GPIB/V ISA, REA D/WRITE for VB, VC/C++,

LabVIEW, LabWindows/CV I, etc.

REA DING BUFFERS: Dedicated storage area(s) reserved for measurement data. Reading buffers

are arrays of measurement elements. Each element can hold the following items:

• Measurement

• Measurement status

• Timestamp

• Source setting (at the time the measurement was taken)

• Range in formation Two reading buffers are reserved for each SourceMeter channel. Reading buffers can be filled using the front panel STORE key and retrieved using the RECALL key or host interface.

Buffer Size, with timestamp a nd source setting: >60,000 samples. Buffer Size, without timestamp and source setting: >140,000 samples.

SYSTEM EXPANSION: The TSP-Link expansion interface allows TSP enabled instruments to

trigger and communicate with each other. See figure below:

Each SourceMeter instrument has two TSP-Link connectors to facilitate chaining instruments

together.

• Once SourceMeter instruments are interconnected via TSP-Link, a computer can access all of the resources of each SourceMeter instrument via the host interface of any SourceMeter instrument.

• A maximum of 32 TSP-Link nodes can be interconnected. Each SourceMeter instrument consumes one TSP-Link node.

TIMER: Free running 47-bit counter with 1MHz clock input. Reset each time instrument powers

up. Rolls over every 4 years.

Timesta mp: TIMER value automatically saved when each measurement is triggered. Resolution: 1µs. Accuracy: ±100ppm.
