FORMULA® TT2 Test System

The FORMULA® TT2 Test System is a universal testing and measuring system designed for comprehensive automated verification of the static parameters of semiconductor devices: field effect and bipolar transistors, diodes, thyristors, voltage regulator diodes, optrons and microassemblies.

The applications of the Test System are quality control of semiconductor devices when conducting tests and studies of newly developed types of semiconductor devices, and during inproduction testing in series production.

The FORMULA® TT2 meets the requirements of the metrological standards for measurements and tests in microelectronics.

Basic technical characteristics and functional capabilities

FORMULA® TT2 Test Systems have been created to carry out highly reliable measurements of the parameters of semiconductor devices. The key technical characteristics of the Test Systems are defined by the following values:

Key technical characteristics
Number of operator posts
Connection scheme
Four-terminal (Kelvin) sensing
Voltage source and measure resources
Range of specified and measured voltage
±2000 V
Number of independent voltage source and measure resources
10; 20; 200; 2000 V
Error in voltage setting and measurement
from ±(0.5% + 10) mV
Current source and measure resources
Range of specified and measured current
±100 А
Number of independent current source and measure resources
5 mA; 200 mA; 10 А; 100 А
Error in current setting and measurement
from ±(1% ± 50) nA
Low current mode
±2 nA...±20 mA with error from ±(0.4% + 400) pA

In manual measurement mode, operators only work with the “Start” button and display panels that show the “Accept” and “Reject” results, with the option to sort devices tested by various suitability groups. After each measurement, the display shows the number of the suitability group, using up to 69 types of grading.

Means for integration with external equipment

The FORMULA® TT2 Test System is equipped with hardware and software for integration with external equipment: probes, test equipment, external devices, handler.
