Explanation of each part

(1) X-Y Display Window The voltage/current parameter can be set on the X-axis Y-axis, and a variety of semiconductor characteristic curves such as Vds-Id characteristics, threshold voltage, and Vds-Vgs saturation characteristics can be displayed. Also several parameters can be set on the Y axis. The scale can be selected from Log or Linear. (2) Y-T Display Window The measured applied waveform is displayed on the time axis like an oscilloscope. It is easy to verify if accurate measurements have been operated because the CS-8000 series can show the pulse width, the measurement point and the abnormal waveform such as an oscillation in real time. All applied waveform data and the data on the X-Y display are saved at the same time. So the measurement result can be re-validated. (3) Measurement Data Display Window This window shows detailed measurement information such as results and conditions, status in text format. The X-Y, Y-T, and measurement data display areas can be toggled on/off and resized depending on the masurement. Also these three areas are linked together.	(4) Configuration Setting Window In this window, the measurement configuration for the device is set. It supports the selection of voltage/current units, wiring changes, etc. in a graphical display. (5) Parameter Setting Window This area is where you set measurement parameters, measurement limits, and switch between Manual/Auto measurements. (6) USB Interface Waveform images, data and setup conditions can be saved to the USB memory directly. (7) Control Panel DRAIN/COLLECTOR・GATE/BASE・vertical/horizontal axis rotary knob, buttons and rotary knobs are located on the front panel for easy manual measurements. The central numeric keypad allows you to enter a numeric value for the parameter.

■HC unit

Because of the HC unit with the high current mode, high current measurements up to 2kA can be performed. The pulse width, measuring period and measuring range can be varied..

Main unit CS-205 CS-210 CS-220 Max.Peak Voltage(Max.PeakCurrent） 500A 1000A 2000A (50V) (50V) (50V) Waveform PULSE Pulse width 10µs～1ms 10µs～1ms (500A range or lower) 10µs～500µs 1000A/2000A Polarity + / -

■ Minimum current resolution 250fA

The use of triaxial and the optimization of the measurement system has reduced leakage and noise in the equipment, so the stable measurement of very small currents canbe performed.

■ Flexible GATE signal output

The gate signal can be sequenced and applied. Hold Time Time variable range 0.000[s]～ 5.000[s] GATE voltage variable range　-40[V] ～ +40[V]

■ Hysteresis measurement

CS-8000 is useful for measuring wideband-gap semiconductors such as SiC and GaN with hysteresis. “Double sweep function” simultaneously displays up sweep and down sweep, allowing for hysteresis observation.

You can adjust the amplitude and time to allow any gate pattern input. Also a preliminary signal enables to be applied to the gate. Devices with hysteresis can be measured under multiple conditions.

■ Configuration for various experiment

The graphical display of the measurement configuration makes easy to set various settings.

The test fixture CS-322 automatically switches the internal matrix switch to match the configuration settings, eliminating the need for a wiring swap. It is also not necessary to switch the connection between HV and HC units manually. Because the internal relay automatically switches through the configuration settings. These functions prevent incorrect wiring during measurement.

■ UI designed for ease of use

The 12.1 inch Touch Screen, front panel buttons and rotary knob provide intuitive operation. The on-screen keyboard on the screen and the numeric keypad on the front panel allow you to enter settings, limit values, and so on. To enable operation by USB mouse/keyboard.

■ Temperature characteristic measurement

Evaluation of temperature characteristics is required for targets used in high and low temperature environments during actual operation. CS-8000 can be used in combination with hotplate and ThermoStream to measure temperature characteristics. The use of ThermoStream requires test fixture and adapters. Automatic measurement is also available with software.

■ Improved on-wafer testing affinity

The output terminals are fitted with noise-resistant triaxial for easy connection to wafer-prober.

■ Safety mechanism

―　Interlock for safe measurement　― An interlock function is linked to the cover of the fixture. During interlock operation, the output is turned off to avoid the electric shock, and the curve tracer keeps safe measurements. Even when you use the prober or temperature chambers, the curve tracer keeps safe measurement in conjunction with external interlock terminal. The LEDs in main unit and test fixture indicate the state of the interlock.

－　Output limit function　－
	Voltage, current, and power limits can be set to prevent damage to the target. In addition, the hardware overcurrent protection function shuts off current when 1.4 times the current flow of the measuring range.

■ System Configuration

HC units and fixtures can be selected to match the voltage and current of the measuring target.
